Sketched in 2005 while observing little black ducks trying to steal fish from Pelicans . No aerodynamic relationship there , though .
-
The Poms refer to this as an Anular Intake , which sounds a bit annal . As its Actually Peripheral , like the Cosmos . So Periferal Intake .
As OS 40 FSR-S's are said to require Crankcase Cooling ,the peripheral cooling intake feeds through around it , The primary section 1 inch long ,
1/16 at the front tapering out to 1/8 in. at the rear - 1 inch mark. Which we all know should halve the cooling air speed , giving it twic as long
to do its stuff.
-
Read the Adaminson Typhoon article back in 75 , with its sparless Epox balsa core skin treatment , and also one or two things on High A/R types they persued .
This thing was conceptualized back there then , sketched 30 years later , and being built 40 years on . . . We shall pretend we're developing Patiance ! .
-
Me Netzbands article on drag Vs A/R had a hand in it too. His hypothesis that a 8:1 A/R has half the drag of a 6:1 ( or whatever )
was born out on my previous 72 span 9 chord 60 49 Merco Mewgull , which in wind gained speed in the Horiz. Sq. eights .
Accelerated through the manouvre . And the wings didn't fall off .
though this here is a separate design study , wing spar layouts similar . But the ribs between the 1/4 sheet spars Grain is Vertical.
Thus the ribs are Three Piece . Center , front & rear . Which explains the slightly square appearanece at this stage.
-
This is taken from a different angle.
-
Apparently I took a few earlier , so here they are .
-
The Spar joiners is 1/8 Ply 2 in wide on the inside face .Tapered to 1/16 over the first bay out . Bellcrank Bolt captured in the top One .
weel , that's all . Part from this is where the curves and curls originate , with a degree of elasticity eencorperated .
Spans 68 Avg. Chord with near full span flaps 7 in . Spinners 2 1/4 . Dunno when itll be finished , but maybe first .
Back to the dungeon to sort out the controls and undercarriage .
Will be a first with the du bro plastic hinges for me, so lectures on fitting reguired .
Moulds for the top decks , canopy & gear leg fairings soon .
will pre dope /sand the wing sheeting , and maybe some white 2 pot for finish .

Its in this ' Capetown ' spec that the features are evolved from . The peripheral Intake about the spinner being evident in the picture.

Matt,
You have a really nice project started. H^^
The Percival "Mew Gull," an interesting aircraft to model.
All the 30 Racers are great aircraft to model. I can honestly say I've built a few of the 30's racers.
Certainly interesting and destined to be an eye catcher.
That Mew Gull had some interesting schemes.
Good luck!
Charles

Thanks for the kind comments . I can see why super glues popular , waiting 12 Hrs plus , per stage , gets the goat up . >:(
-
Thats the cooling duct to the case , a good 1/16th in. Its sitting ' going off ' with the aryldite , at the moment . pinned & gaped even . :P
-
Thats last nights effort , the vane / spacers . Dialed in this morning & another ' delay ' while it kicks off . >:(
The peripheral ducts I suppose the moe demanding part to set up right. apart from all the others . LL~
This is looking forward ( from the Cockpit :##) overbanked in a turn . :-\ ;D

Heres the vane / spacers . and the results of carelessness with the hacksaw . :-X

It gets Complicated ! as theres THREE series of Percival Mewgulls . ( separate designs ) and Henshaws G-AEXF was a E2H and went through
continual progressive development . Edgar Percivals late one G_AFAA was a E3H , which was another complete redraw .
This one im doing is Henshaws in ' Cape Town ' record spec . elasticated !
(https://capechallenge.files.wordpress.com/2010/01/image008.jpg)
My previous 72 span one was 38 Kings Cup spec , ish .

(http://www.controlline.org.uk/userupload/613/0002.jpg)
Though Comparable , aerodynamically the one being built is a different ballpark .
Was astounded with this at the two lap glide , and that the wings didn't fall off ,
even in a 20 mph wind . Unmuffled Merco 49 on 15 or 20% nitro on a 12 x 6 wood ,
would four stroke around effortlessly , tho 70Ft lines are as short as youd want .
(http://www.controlline.org.uk/userupload/613/0001.jpg)
That's a Bedford , not a Chev. >:(
Flying it here ,reserves on the shore to seaward of those lakes , pines down the beach line . youd get the onshore breeze over the pines ,
and the ground breeze left to right along down to the right . So wind sheer at about 50 Ft. alt. and a big rock of
the tips through the downwind loop of the overhead eight . Though id didn't drag me down the field or go loose
on the lines .

The Perrcival Mew Gull looks like a stunt model that was later blown up to full size - not the other way around. You are off to a great start! H^^
-
Cheers , the Orange Crate & Eclipse articals were devoured before drawing the green one , thats a 23 % airfoil .
The new ones thicker with long flaps , to chase the elusive " Five Foot square " tho Id considered this layout 75 .
Michealangelo and Orvil Wright can take some of the blame too . . . ;)

Got the Bellcrank in , which is one of those hurdles on these things .
Only SNAG was the washer recessing itself and pushrod binding , so threw another washer in . As the center on leadouts / Rib leadout cut out line
gave me a whole 1/8 center from the ply plate , which is a notch more than I usually allow , then end up having to put a trench for the pushrod . >:(
Washed it all in acetone & assembled with grease & lubed with a few drops of Moreys . Kink in pushrod is at edge of ply when rods fully forward ,
so rod & leadout don't occupy the same space / time continuum . or place . All free and easy and No Slack . Which is a good start .
-
Its from 2 m.m. steel .
About as minimal as I go , so if it freeflights across and gets arrested by the lines , it wont fold up ( we hope ) with say a 1450 gramme plane in a 20 mph wind .
we hope .
Leadouts are double .018 7 strand laystrate . Pushrods 3 / 32 ends . Likely lapped , bound & soldered . as the aft ends a bit light , so far .
-
1/8 brass tube & brass washers for leadout & pushrod bearings .
Uses a 5 / 32 mounting bolt . I will ad another 1/8 ply plate over the spar ( outside ) so it cant weave around and come loose .
Gives it a bit of cantilever support , we thinks .
-
Picture of where the Airfoils at . though ive used 1/2 for the flaps & Id drawn 3/8 . Makes the t.e. 1/8 thicker , as ive just figured out .
Nice quarter grain flaps are stiff light & torsionally good anyway , and a bit late to ' adjust ' that . Works in o.k. but didn't check before cutting .
Most Likely for the better , as less drag & stiffer . Perhaps . ( 1/8 deeper at hinge than the lines on the fuse there . )
-
That's what I love about your planes, Matt. You don't hold back on ANYTHING! 'looking forward to seeing more.

notta lot done last week on this.

The Porcipine , back onto it . pre Doped the sheeting with two coats Sig Nitrate & blocked flat with 220 wt.
That's Dope in the Coffe Jar . The REAL coffe jar is bigger now . and on the shelf .
-
A few details if the pictures legible .
Sci Fi , man. Might have to sit back to get it in FOCUS .
Inside the wing , sheeted. The little dots are beads of excess glue , titebond .
Was Conveniant doing the rear sheeting first . The Structures similar to the Beringer FLAT SPAR set up.
Spars are 1/4 sheet. you get two from one four inch sheet . The 1/16 TE sheetings FLAT . The inner faces
are synomonous at the joint - SO did the top sheeting first . Doing the bottom sheeting I found you could
get a finger thru from the front under , to get the joint nice .
Glue on the t.e. & ribs & front of sheet , Fitted & pined ( tacked ) forward . Worked up firm to spar
then te tacked and a block used to push down sheet at ribs to ensure ( I hope ) a decent fit .
Went over it again after pining after the glue had firmed up away , with the finger tip then a block ' seating ' the fit .
-
Wong Picture , ACTUALLY the beads are on THIS one. Both are looking aft , the t.e. is 1/4 x 1/2 .
The twirly thing across is double .018 laystrate leadouts . The Camera lens is IN the open front at the l.e.
Far Out.
-
Threw a couple of 7/16 nuts with 5 g. lead inside & pva , for tipweight . just Over an ounce total , bar glue & keeper .
Nice shiney new nuts that came with new bolts for the flywheel for the 4.1 Ford six . Finally found a use forem .
-
Will show the leadout guides as it shows the shallow angle thru / along the under spar , and the ' tip block ' shape to catch the t.e. & l.e. sheeting .
Would be easyer to use Beringers ' wrapped l.e. & eliminate the 1/4 sheet l.e. whichis so soft moulded sheet'd be stonger . AND an easyer fit .
-
A Bit TRICKEY to get adujustable leadout slots through at that shallow angle that don't catch the wind , & the bolt'd have to be vertical ?
unless some cunning sod has figured it out ? tell me more !
that's a 3/32 brass tube ( with the cable thru. ( drooping @ the right ) ) . epoxied with a 1/4 x 1/16 ply keeper across under spar
-
JUST one more, seeing we're at it.
Tip Blocks & Spars over a a 1/16 lite ply former after the end rib @ centerline . ( cr. of airfoil )
The spars are planed to alow a easyer curve over the last few ribs . the whole thing narrows dow towards the ends .
( tips ) so the spar dpth also tapers going out , when planed & bloked ( sanded ) to the curve & flush with Aft Sheeting .
Ive used 3/32 sheeting for the l.e. A bead to the front edge and glued to the L.E. ( its drying now )The glue to Fr Ribs &
the sheet to spar faces , crve the sheet down & pin & let cure .
Unbenching PVA type glued structure prematurely ( a week in winter a few hours in summer ! ) can lettem get askew ./
This dithering about building lets the assemblies stress relieve and harden up at least. Usually knocking a plane up in a week or two
then flying its only feasible in summer . winter a pva'ed Combat wing Would go ' all soft ' if flown at the weekend after building in the damp .
-
More toil & trevail .you can see the flanks of the spar shaved in to match the sheeting.knock off the ridge curved and presto. An Airfoil .
-
Some Resemblance to an aeroplane .
-
Looks a bit like a Nobler . >:D LL~ :##
-
Infernal BLOTTING PAPER WOOD .
-
Not to Worry . ??? With Titebond it removed o.k. ,Shaved the top of the L.E. down flush with rib ( which is easier fit than trying to get a exact fit BETWEEN a L.E. & Spar )
Set up to go with with this Flat / Parrallel ( fore & aft ) Spar trip might be to shave front & rear of spar Before Fitting , maybe ' down a wire ' the sheet depth. Though might pay to leave four or five even spaced flats across , as you can put a straight edge across , with say a 1/2 block & mark that line down the L.E. & T.E. ,
Spliting this ( halving ) gets an exact centerline .
Both these would simplify the set upquare Ribs , Fit the L.E. & T.E. , Taper ( finish ) L.E. thn cut inside a template across to spar. Aft is straight line .
only Problem is youd be better with knife that cut round corners ! .
Heres the Sheeting Refitted with tape holding down & aft over Ea rib .
-
Damped the outer face of the 2 mm sheet and gave a bit of a curl across it , before nailing it down.
Heres ' the end ' , with its wonderous curves and intersections.
-
Done a bit more on it , Elevators at the moment .
-
Morris ? Elev Horn .
-
Tapered 5/16 cedar let in for horn ears , Trim the ribs , and true before sheeting . reinf. for hinges in there ( 3 a side )
Id put the ribs on the LE as rectangles , found ' square ' of the bench , for the TE centerline , then marked the ' Vee ' of the ribs ,
the sheeting / taper is steeper as it goes out , so one needs to keep ones eye in , as it goes . To keep the symetry with NoTwist.
The Orange Crate & Eclipse ( Adaminson ) were referances for development, with the peripheral cooling subduing ( we hope ) the FSR runaway .
-
The Weight , Bare Airframe with motor & spinners about 39 Oz at the moment .

Will have to Floor the Cut Out to improve the Torsional Ridgidity .
Despite the 1/2 x 1/8 spruce runners at the sills , the area lozenges when you twist the Aft Fuse .
-
Rear under is 3.0 hard @ 45 Deg. along edges , with sheet sanded to 2.7 underside .
Tapered the first inch , it mates into the lower wing spar to integrate the Thingo's .
Id put a offcut of 1/2 over the joint with a 1/2 Sq. Oak a metre long pulled & taped to the wing out there ,
so that the joint was Clamped Overnight ( using P.V.A. Glue ) . Wing resting on empty water bottles & Weighted at Root to Neutralise the pull,
rather than risk it shifting / missaligning .
-
One for the Road . Cowl , Wheel Fairing Buck , Tail Skid/ Fairing , and ' one or two ' other things to Go . Weights 39.5 At the Moment .
Figure I will adjust Lines , Weight and Length , if leadout Posn. is problematical . The last one ( jolly green Giant ) was Fine , & NEEDED 70 Ft.
Figuring 65 to 67 of .016 solids as Base .

BIT LATE IN THE DAY for Design Changes , the Nose Flanks needed to be at more of an angle in , going down .
Veed the formers at the sides , an inch down at the L.E. 1/16 in.,
3 / 32 Behind engine to thrustline , & 1 /16 down to the nose ring . :P :o
Been IRRITATED by this for most of the week , Flash Pictures a day ago of front made it compulsary , to get the cowl to Fair In properly .
Worked Out Nicely , was a bit stressfull till a fait acompli .
-
Gets it so over the cylinderhead The cowls not four foot wide . ;)
-
Underside of rear lower deck , Masking on centersection to avoid gouging up sheeting whilst refining contours .
Fitting hard leading edges to Tailplane . That and fuse sides were cut pre 08 or 05 even ! The latter I think . :o
-
Decided a splitter at the head was min. requirement. Id dithered about & made a cylinder shroud , so it ended up in it .
-
BAH , one or two pieces .
-
The Asphixiation TEST . Cut back corners get even distribution across the head .

Thus.
Requires at least three or more deep breaths between tests to clear the lungs . These turkeys that gut drag ciggarettes must be feral .

Matt,
You have enough aspect ratio there you could sell some and still be fine.
Kidding! I'm kidding.
You did a great job! H^^

-
Very Good .
Was tempted to leave the outer @ 36 in. and add a notch to the inner tip for about 74 span & 10 : 1 A. R. , :-\
figured the spars'd hack it , but designed at 64 for the ST .46 or 68 for the 40 FSR , its 68 1/2 , but we cant be picky .
Couldnt see the point in having it to long just for the hell of it , but I did think about it . :P S?P
Heres the Undercarrage I DIDNT Use .
-
A Bit of Blacksmithing . 16 G. Galv. of some building material maybe .
a bit of dressing got them down to 11 G. From 14 . The U/C ' flex ' for shock absorbings better than previous set up . ???
Probably as the heat freed the entrapment on the torsion bar , maybe . Should just hack our moto-x tracks , as well as the tarmac .
What Tarmac :P :( .
-
There is Something Afoot ! . ;)
Hard Solder , Plenty Strong . and should break away if theres an earthquake , leaving the airframe intact. Thats my Theory . Hopefully wont test it .
-
6 3/4 before we run out of air .Level .

Them and a bit of a whittle in the wee small hours .
Tidy that Ex ole , & carve the trouser plugs. Upper Leg Fairings , Er , . & one or two things . . . . to go . H^^

Matt,
You have great creative building talant.
Really nice project. H^^

Looks a bit ' acid trip ' ish .
-
So tried a blue ' life saving ' bottle of water .
-
Chop a hole in the base , feed in the plug , force in a stick under it , a rotate untill grilled .
the neck seems thicker , so windshield end front , tickuly for fighter windshields .
Watch you dont hole or scorch it . Blue came out almost usable first go .
-
Spot the differance .
-
Beautiful airplane Matt! I really like the unusual planform and can't wait to hear how it performs. Please keep the pics coming!

Bin Elsewhere .took a bit of cleaning. tried the boiling in anti freeze . Dont look to bad now . Utes Brakes are near done.
-
Right , Casting plaster ( from building supplies center ) moulds for trousers . Not ideal , but quick sets , wont disolve , and goes Chink when tapped .
-
Double 3/4 Oz. cloth , set crossweave ( 2nd layer 45 Deg. to first .
White gunk is rustolem . Better to polish the buck & wax - ignore
bubbles in mould ? . Scrapes off - anyway . Er. . release agent . :o
-
ETXC .
-
>:( thought I might have to try 3 piece , as per F.S. , the fits a bit loose on upper leg , so will try moulding & fitting a ' front ' fairing ,
and afix rear sides to that . Its got to have some give, mainly fore & aft . As I didnt want the legs to rip out on our motocross tracks .
( almost no hard circles here ) .
-
Double 2 Oz. cloth with rienforcement to edges . Fits a bit close but thats how it was done . ABS'd be easier , vacum molded .
-
Ditto .Bolts a temporary fixture, axle likely 5/32 brass tube , fairing about 2 mm thick there , If I make it 1 mm thicker .
-
Shoulve really made my own 1/8 horns , as dinaye want other than ridgid control system , As id like to seee how it handle ' sailing weather '.
reinforced the 3/32 suckers with the offcuts , aft & inner . Hard Solder ( 60 /40 ) . to shorten torsion length . The Green Sucker Id bent 3/32
arms with loop & brass tube for pushrods , Giving em a good twist , the 3 in or so in the front of the flap came free in the aryldite , giving
back off ' as per Beringer . as they were little ' Beringer ' flaps was of no account , thats hoe He set them up .
Incedently was Drg. in old Aeromodellor with flap configurations ( Experimental in 50s ) with short small one on center T.E., As per Mr B ,
almostish .These are longer . :## Full span nearly so would appreciate if they were not wobbly .
Put wet & dry paper Fwd. of arm & tended to keep vertical - wing down . Also had moist paper towel & cooled it half'n' half , or better .
TIME with iron on it seemed to be the relevant factor , to incinerating the airframe . Always have a bucket of water on standby .
Unless your electric . %^@
-
Undecarrage Fairings . take 5762 ! . Well , three .Anyway . >:(
-
The Usual two layers of 2 Oz. cloth . Actually there two side & one front or two , so theres overlaps . Layed up in the plaster mould .
A strip of cardboard pva'd on the top of the front mould gets the rebate for the rear to overlay flush . Plaster will scrape / sand off . After theyve hardened up a few days .
Still undecided on finish . Could get it silver at a few Oz. penalty overall . Tho just Tissue & dope on these ( fairings) would match the rest .
plus $ 40 for can of quality U pol silver . %^@ , though it'd show off the lines- a sanded thin under the outer tip shows the ribs - Which'd look HORRIBLE silver . So Clear's the Go . :P
-
No Problem with the Wheel Pants , only 10.864 attepts . So Far .
Reversed the upper saddle to clear the rear fairing / so it drops lower . So cut of upper on wing so I dont incinerate the sod .
-
Expect another 10 pages on these , before I get them finished . >:(

Gave up at 7 am after doing a C.S.C. muffler copy , two tanks , and . . . a few other things , and hit the sack . Had thought Id fly it Saturday . Got clear cote on ,
Eastwood paints diamond clear ( pitcher of a wheel on it ) seems nitro proof and clear gloss . Belting the slightly to wide tank into the nose of the MC72 wasnt a good idea .
Not to deranged from it , surprised I could hook it out , with a alen key twisted under it , using the vice grips . So a narrower tank ( 48 mm ) for that , & maybe one for the s6 ,
and off to the wide open spaces next weekend . Canopy to fix and cowl fixing to make , likely a dog leg ( z bend )wire lever trap , fwd to release , scewed to bulkhead ,
traps ply duct floor ( roof ) .
Looks likeitllbe 60 Oz. :( Still , probly help it in gusts & should carry it o.k. Id hoped for 55 , to get right inside of things in the turns ( corners ) .

Well , She's ' flewed ' . Threw it up , once , up Musswellbrook .
think the Fuel ( methanols ) off , as none of three needled right , and prviously in the twin it wasnt needling well . 4/4 might mean something .
IF I could get some , for this weekend ! ?
ANYWAY , seemed o.k. so threw into reverse wingover , did in & out loops and a few appaling squares , dryed of and cut , after trying to get it to.
Id meant to use the full line spacing at handle 7&throw a Oz. of lead under the tailplane , beforehand . Tank Full c.g.'d be on the L.E.
Wheels are to rear for grass , but we knew that . Had in the bigger intake , now fitted the smaller ( no Muf Pres . ) & in the MC 72 ,
before I figured the fuel might be shot .
Sat out well on 65 ft .018 laystrate , so will go to 70 ft odd . Canopy was just taped on . the Paint had a week to gas off , so was just under
55 Oz. , which is a relief . Nothing like spending months going overweight , so a waste of time , >:( So its at what Id hoped for there .
Might even sneak a coat of paint on , one day . Silver or white . :-\
only real issue is nosing over on launch , so do I fit a noseskid - like a old T/R one . ? seems the easiest fix . The Conc. Resivoir in N.Z. would
probly be o.k. , Ludnams got the best manicured cirxcle around here , So , We Will See . Busy on a few other things for a bit , but will tryn find
some fuel .
-
o.k.got a r o g with a push from Geoff Goodworth .
the needle worked , at least on the H40S in the MC 72 .
Leaned out through flight in the Mew Gull ,
65 ft. of .014 single strand , new , on it .
seemed to handle the variable light bumps & wnd directions well.
Fuel was big improvement
Grooves in level & rounds .
seems a good four stroke run will be right , we hope .
But a decent radius & drop out of the turn.in squares .
even inside & out , hanging a loop on one line , without going feral , dunno if id go much past one , unless she's slower .
you hit the wake there and a few other places, expected as its about 23% wing thickness .Blunt Airfoil with steepish fall off back of the spar .
good line tension . one lap glide .
sort out the leaning and the pilots neckand brain cells and itll be marvellous .
gassed off so is at 55 Oz . No power shortage .66 1/2 ft .018 7 strand steel laystrate on it today .
Hoping the horns are strong enough to hold station in bad air . Improve the cowl catch wire . ( refine )
Think theres enough room for a clunck tank , er wot . maybelighter .
responsive so needs a steady hand unless your into zigging & zagging :P
30 G tyre Wt.under inboard tailplane ( on Fuse. )
soldered & lubed the axles .
may try a flight with the cowl off,to see if its too sopphisticated to work. n1

Matt,
How about a picture of the plane at the field ready to fly? ;D
Thanks, Jerry

Down the field today , with my ' team race ' pitman , of the Metkemeyer Launch .
A wee shove gets it moving , before it trips up . Ex PVA squeeze bottle ( mustve mixedem up ) had coagulated the filter ,
EDIT : ( seems Im told armourall isnt what It Used to Be , and Silicones up your Filter - I was told . The squirt in the last batch mustve been the new stuff, doesnt ' anti foam ' either )
explains the runs, 2nd flight today we used a 12 x 5 top Flite wood prop , bit too 4 stroke , so the tension was down @ 70 Ft. on the .018s , the airbourne pitchers are from .
so I'll cut a set of 14 thou. solids , or two .
& maybe some .016s for if theres a breeze .
-
Pilots brain at half mast , but got repeat hourglasses , a few Sq. eights and a few clovers out of it .

Wandering off of water a tree can get you familiar with venomous Brown Snakes .
Had one for a guest awakeining one morning . a bit teritorial but didnt like me lunging at it while i was still asleep .
' Oh , a Lizards Tail dissapearing into the Grass .
Sunning itself at lunchtime , it wasnt a Lizard .
FS or FX 46 in the other beast .

;D these ones are from Greg Via Email and posted by fumbling and stern glares, pushing buttons and persivarance . The previous arfe from my cell ph camera in the harsh light of day . Miday even .

The Pitmans better at Metkemeyer Lauches than his cellphone is at pitchers , were told . But theyre better than nothing, you doubters and scoffers mw~ . :-\
-
The Spelinks a bit off to , but If I got iot wright someoned hack in changing it as I go. At TIMES .
was goana edit em , but the pixies are a bit out of it , and itd look a bit furry . So youll take what your given and like it. Or Else - No More Gruel , you little scoundrels . ??? :-X

Sheesh , he can count past three . Im told theres lots of pixles , too . Just as well it stayed going. Right up there . %^@

As my computor technieque consists of pushing buttons and things untill something vaugely hoped for happens , and its 23:52 Hrs , Talking Loudly to it at the moment might not go down to well , here . So this is it for now. Folks .

Wong Won . n~ Others found themselves through the maze , now. Silently too . almost .

It Seems to be hideing up by the top of that pylon there , on that one . I MIGHT get the RIGHT ONE 007 ON , This Time .at the 2nd or third attempt. LL~
We Escaped ' instruction ' as other conspirators are tied up over the way , at the moment . ;)

Here's one I've had a chance to edit.
It's the first time I've used my phone for pics other than just happy snaps. The hardest part is framing when the screen is reflecting the sun back into your face. Still I managed to keep the plane pretty much in centre.
-
WOW!
Great photo, great plane and nice flying.
Be nice to see the model painted and detailed.

Yes . . . Well , it may actually happen , Not Sure WHICH Christmass , but ' By Christmass ' might be appropriate . :-\
Anyway , Dragged it down the big smoke , and after No Rest headed of @ 7 a.m. . Left the Batteries charging on the bench .
Fortunately someone was kind enough to lend me a glow driver .
Definately been overproping it . First Fight was on the 12 x 5 - leaned off as it went ;
ive used a 3/32 K&S toob for the vent , 1/8 over it outside the tank. Filling the sucker , or to be more concise ,
Pressure on it from the syringe , to force fuel to the needle - if BOTH pipes are open uniflow & vent/ no cap ,
the uni vent will blow fuel for some seconds. Id think 1 or two Sec on a open vent more correct .
Looks like another tank is required there . Maybe 1/8 uni tube with a 1/2 in long 3/32 tube ' regulator ' at the outer end ? ! >:(
Put a Magnum 40 FSR clone in , the cranks 5 deg ' narrower ' ea way THAN THE FSR-S ' stunt ' crank timing !
Sleeve is considerably higher timed than the ringed FSR .
Enya 3 Plug cold cutting %^@ hope theyre not pirate clones ? Running in a good healthy 4 stroke with a 11 x 5 Top Flite Ancient wood .
Tripped on roll out . One U.S. propellor ( Un Servicable ;)) >:(
Threw a Ex Windsor ' Somewhat ' wittled 13 now a 12 x 6 ?? with much of the blade ' gone ' - By File . ^#!*^ leaned off again .
HOWEVER . . . .
-
Got a reasonable flight outa the MC 72 , with 15G tail wt. Id decide , to get it to balance ' about the spar ' , as it did .
dunno if the 40S Max is gunna be to gutless & Thirsty , Might bung the bypass / boost on a Iron FP OS and see if thats the trick .
Lighter Still . With a 11 x 5 master or thinned Zinger , it was ' in the groove ' with the open Ex 71 Torp 40 , PREVIOUSLY .
The MEWGULL ! Id Cut in to pull the pushrod in on the Elevator Horn . Being a ' shoe horn ' FIT , it didnt want to UN , despite fileing,
muttering glaring and subdued brutality . Eventually got it off , the in the prepared inner bushed hole , Rewashered & Re bound & Soldered .
1/16 Ply Epoxied , let in Flush , as its all ' stressed skin ' in my humble outlook .Tossed the previous tail Wt. to start @ Sq. 1 .
Ratio is about 2 : 3 now rather than the previous near 1:1 , more usefull on an AFT. C.G. ,
As the Concept was Fwd C.G. it is , armspan wont make the tips :-X , buts about the front of the spar , maybe 1 1/16 Aft of L.E at C/S . %^@
As Intended ( Similar to my goof of a jap. Hara Noblerish device that steered like a tractor , for those uninthe know , they turn tight for furrows .
SO , When the speed was roghly o.k. and the pilot ' almost there ( or THERE at times ) it was in the groove & turned fine .
Definately been overproping it , bouncey and needles good on the 11x5 rather than twelves ive been trying - after having seen Mr Hunts ( pictures )
of his wide blade 11 x 6 three blade . ( Must Make a note of the intakes ( asign the shipo a LOGBOOK ! ) and find the big ones ! ) Fond my ' missing ' line
clips up in a cnr. the other day . after 2 or 3 MONTHS concern . :( :P :-[
Back on the 70 ft .018s for now . Need ' a hand ' or more spare to cut some New .016 solids . And Get some ' 14 inch reels ' as was the Kiwi Wont in the 70's .
:P
Crick in the neck has O'Head 8s to ' out of site , far from out of mind ' just now , So Priority is The TANK & do a few props for the spinner , & maybe a Nose Skid LL~ T/R style , :-\
Lined up a few .45s , tho looks like maybe the 40'll 4-2 , the OS dsoes ' the switch ' on the deck , fine . same angle ' cut in ' inverted & upright . Havnt pursued the Magnum 40 there
but maybe it will , Might do a few 11 x 4 s too , need the centers pulled in for the spinner cut outs , or V c V ,
May have it out Tomarra with the great cinamatographist LL~ LL~ Thy Bro . ( Thinks He is ' The Director ' anyway . ??? )

When the Hole in the Boat became a Water Sout , He Drilled a Hole to let the Water OUT . ;) Bunged Acces Cuttouts . 2 Posn Horn , she wont be going back on the outer unless I take 3 Oz off the Nose . %^@

DOWN the FIELD yeterday / Sat. Kuringai , acyually . 11 x 5 master Id Bought for the MC 72 on it ,
First Flight GOOD , leaned of a little toward end . F'ed up O'Head *s COMPLETELY , will have to pantomime the schedule , to get ' the moves '
right . as Im so rusty with winter & a long lay off . Slight wing low inverted at times , more discenable with speed .UNUSUAL as o.k. upright .
After Several stern glares at the FLAP Alignment , I gave the treatment to the ELEVATORS ( one rests near the rear windcreen , and getting it
in & out can get a brush ) Volia , inner was down maybe 2 mm . Funny its effect was inverted & tension at crossovers . REALIGNED Equal to R .
Checked the feul Filter . Oh Dear . Id dragged out old fuel , I think 5% , as I couldnt be bothered using / wished to reserve my few pints of methanol .
Armour A./ in It I recall . and half the cats breakfast & a field of oats plus a copper mine , by appearances . Blurry Pitcher .
looks like that indeed . ' will not respond ' >:( maybe tamara . maybe another PLUG will do it . ;)
-
cleaned filter & it was LEANEr & leaned through run , on the second flight . HB~> HB~> HB~> Got a Good ' Wheel Run ' landing though ,
so the undercarrage is not totally useless . just needs a nose skid . LL~ as nose in dirts inevitable at the stop. It seems .
-
Thus it is inevitable I will try Mr Zambelli's head chamber mod . Otherwise not going bad for the highest ( 8.625 = 8 5/8 ) Aspect Ratio F2B Thing
known to mankind . :) LL~
Using the @ 70 ft. .018 laystrate .
Stays out there .
Pilot needs P.T. Commando Course & osteopath / CHIROPRACTOR. nOT A bL^%#* AMATURE , EITHER .
-
Mild Day , Mild Wind .
-
Mark Batty's Yatsenko take apart which he leaves assembled , for local operation . Put In 4 or 6 flights .
-
A chap who shall remain nameless as he wasnt observing to give his expert appraisal of the Flight of the Mewgull , other than Bl**dy Loud .
We will blame Bob Hunt for this , as its a copy of his C.S.C. woodville W.C. one . Wich had a few similar if politer remarks, in ' the press '.
Harsher rasp with the magnum than the OS . Looks like a more socially acceptable alternative will have to be provided .
Rojett 60/61?? in there . Jeff Reeves actually. just im not good with names , and that sounded batter. But I remembered .put in 2 or 4 flights .
Looks Like a New Tank & set up a ' stunt ' head per ' Zambelli ' is first on my agenda . Maybe rub it back & paint white / scale tripe before
fuel renders it impractiCaL .
-
Latest Plot to even the output / power supply . Stripped & cleaned it . PARTICULARLY the Gudgeon/ wrist pin .
Reversed the case & Rod. $ 30 engine from California . Bearings were notchy / gritty as hell from sitting .
Just WD 40 and the ' mustve been dryed oil ' is all smooth & free . Wrist Pin got GROT removed or it wouldve been ??? as froze in piston & verge of corosion .
Care with Circlips / long nose pliers And SEEING THEYRE SEATED sees theyre seated fully home . So they stay home - rather than screw the bore .
IS Magnum 45 FSR abc , crank timing near 45 / 45 on this one . V near . Will have to drill THIS front housing for OS intake / NVA , as per .40 .
New Fuel Tank is high priority too. Think the 1/16 bore - 3/32 tube is somehow tripe , or the tins to thin . also will do the tounge muffler for a pressure nipple .
and see if its a ' acceptable ' noise level on THIS motor , before I figure to configure somat else THERE . :(
-
In Case you cant read that photo , if you cant read THIS photo , youll have to take it on faith it says FOURTY FIVE , or 45 actually ! . S?P
Hoping ( thats hope , not hop ) it'll be happier on the 12 in props , maybe a 12-5 tho ive 12-4s. Exhaust timings near 140 , rather than the 40s 150 , and the blowdowns less too .
-
Latest atanks on Tempt .
2 mm holes driled in baffle , then whacked with a centerpuch , over a hole in a stick , to flange the flow holes . Thenem Filed Even .
Tis about 150 cc , 6 Oz. , 1 in. thick . Fits in easier & LIGHTER which is a bonus .
Test the tank & 45 set up tomarra . S?P
-
Well , after sh*t runs with the Magum 40 , the 45 cutting & the OS leaning out ! . >:(
-
We got ta whittling .
-
Think most people'll recognise THAT . After drilling bearers 1/2 Fwd for the shorter injun , decided to LEAVE existing mount capeability too , so plates have Four Holes
Ea . Ea. side , & 8 nuts altogether !
This suckers a few ounces lighter than the Magnums / FSRs .
Reworked cowl etc to fit , and gotta bitta weight out .
First coat of F'Glass cloth looked magnificent . Second looked decidedly dodgey , and took cowl Wt. to 2.3 Oz. MORE than before . So looks like a lighter one
is on the cards to replace it . >:(
Wether the opening out around the motor did it ? the ' Smoke test ' ( Choke gasp ) has much smoother flow now .
a silly shot of the peripheral ( aROUND THE SPINNER ) INLET DUCTING .

Got to put a flight on it Monday . ( yesterday ) Fitted 45 grammes tailweight ! :-[ under the elevators , to get the C.G. to 2 in. behind the L.E. at the Root .
Blowing a trifle , 15 to 18 . some were saying 30 . A smoothie cut loose & went in , and only four flights in the O.T. / Classic comp . Mk 1 T bird shuddering
and way open in the o.h. 8s , and definately four round things , somewhere , which mayve been a clover . Only Flight to approach all the manouvres .
My trundling round with a few consecutive insides & outsides , to see if it wound up . NO . After a wing down on the launch , it snapped out quick ,
and inner 30 deg down , then the wind mustve hit the outer & knocked it flat , on the first outside recovery from inverted . The second getting a bit of hight ,
er trying to , the wind held er downish , hit full up . After 1/4 loop , visulised pices of Mewgull bouncing skyward spectacularly %^@
Just as well I held full control in - whistled round and cleaered by a few feet . maybe .
A few nice triangles , a few times . The super Tigres pulling nicely , if a bit rich . a .210 intake , muffler pressure , and a 12 x 5 rev up Wood .
Its got ' the turn ' now , with the C.G. back somewhere more sensable , the motors steady , bit of a bump on landing , trying to get er down
before right upwind , as shes a bit of a floater . felt very light on the glide , with the headwind , cut just before downwind , somewhat touchy
or was it the pilot overcontroling .
All set for further endevours anyway .And two puple cushions , for suports whilst sanding P-51s etc .

Gees , Ive missed , I Threw a FP 40 in it , after slotting the engine lugs . Left the Tail Wt. on ! 12 x 4 Nylon tornado . ST NVA .
Now , This Motor has always ' run away ' . I couldnt give it away . Series one FP , the Iron swage case job . Id picked up a later FP 35
And Read Leonard Newmans , and others , stuff on FPs . So wasnt expecting satisfactory results .
Surprise Surprise , it behaved itself . Flew good in gusty air at S A T , Blown In once or twice but flew itself out with minimal footwork .
Yjey Called of the Comp. I think only one or two other got Airbourne . Before mutual consent caused abandonment . After Id dialed in a few things .
More Go and 10 G tyre wt out there for a bit of drag to hold the tip .
Did a new lighter cowl to fit the ST too , nowll get trimmed internally for the FP 40 OS . which is lighter again than the 21/46 . still the 25 G lead
at the rear hinge line . will have to ' internalise ' this . once finalised . post clear coat . :-\
Not to Worry . Gave it a good scrub . Should put a few numbers / letters o it , in tissue , the green wing & fin tips , and get the 2 pot poly on
With the AIRBRUSH .
I think in hindsite the P-51 got a double dose . Live & Learn .
Figured a final deatail on the upper leg fairings . Not a lot differant to original , just grain lengthwise rather than vertical , so max resistance is to leg swing.
Finally got these recordings got ' in the public domain ' . so There you are .
Hairworthy . %^@ Couple of flights on it , Here

2 .nd I try'n spin the wheels up ( to free em of a bit ) didnt bind till I soldered the Axles - Dagg / flashing - shaft to washer . Knife Blde in 7 spin has freed em , at the 50Th Attempt . >:(
This isnt entirely succesfull .
thinking its the Magnum 45 in it .
-
Well , ive ' resurected the thing . New Fuse , + 1 1/2 inches aft . Did the Fuse. for the Staler 51 RE . but since fitted for FP 40 . Dunno if this was a mistake . :(
Redone the spare cowl for the FP . Heads inside . Stalker head would protrude plus would need a cut out for muffler air exit . So the logic was ' keep it clean ' rather the orifficated .
Will see if some pictures ' go on ' .
one of the Full Sized , anyway .
(https://images-na.ssl-images-amazon.com/images/I/81zNVv3fCgL._AC_SL1500_.jpg)
Getting inclined to do another ' green ' one , for ,maybe the Merco 61 . THAT original was with a Merco 49 . Darn Good. Hot Ship . Pointy Spinner .
V differant to fly to this ' High drag ' version . Ive increaed the flaop chord to loose the thick T E . Had to reskin, again , the top of the elevators .
ANYWAY , ready for tissue covering . Tank Bay , cowl etc etc all done . Hopeing it wont ' trip up ' on the small wheels. Now . But figure dragging some carpet to the field might get it running free . If needed .
Would be o.k. on tarmac. Dunno if the new Nats Site has the Stunt Circles tarmaced or just the T/R & Combat . VD~ S?P

We'll take the clamps off , to fly it .
