First the TYPHOON .
OS max 80 . ( 1970 ) the needle roller big end Series one one . Was Unrun . A tank through on the deck .
30 % oil no nitro .
On ' The Launch ' the cowl jumped ship . As the Magnet Glue didnt hold . And Id forgot I'd meant to put a ' security rubber band ' on .
Way rich & uncowled . 6 sec. laps . So cruised ' bedding things in ' .
-----------------
Second was a heathier setting . Squares & triangles & things . and I think a few hourglasses . maybe .
A Outside Triangle , the ' Down 120 Turn , Got a ' reaction ' where it turned in . And picked up ( power ) . :-[
Nevertheless it flew itself out before the end of the leg , for the next turn . Has 1 1/4 or 1 1/2 assymetry .
Will get a ' Rabe Rudder ' I should think . And ' Lost Zone ' on the Elevator Horn . Also .
Was ungrovier low , But Exits corners well , and clean . Not OVERLY responsive , seeing its NOT Nose Heavy . :-[ ( I wonder why )
Theres a 1 Oz. ex seat belt steel spacer , in front of the prop . which fitted the 5/16 Fox prop Extn nut pretty good .
SO , we're not displeased with this thing . Over all . Shows Promise . ;)

Just one on the SPITFIRE . A Mk X P.R. with the invasion stripes .
Left the cowl off , as many say start uncowled . Particularly when its a blank firewall with the cooling exit up through
past the engine & out the 8 mm bore Exhaust pipes . We shall have to see if this is satisfactory , or delusional . :(
Dud ring seating , a burst on a prime & it was fine . Fueled it was reticent . So a borrowed electric finger & 6 turns on the
fine Toon Needle had it whirling the 13 x 5 1/2 T F prop . :P After a fassion. A bit dry overhead .
A few clover leaves & squares . Sloopy horizontal eight , consecutive round and square things & the odd triangle
and hourglass . Again on 65 ft of .018 . Inside wing end on upright , can see its underside inverted .
As it has diheadral youd expect to .
a little more pull than the Typhoon , but both not arm wrestlers .
Motor, a last series ST 60 , is a bit doggy , but will investigate its innards . ST 51 intake . 3 window P.D.P. motor . Was strong enough no sweat ,
The intakes ( just ) bored to 0.313 odd . Gets the tank lower for vertical C G cognesant with leadouts in top of wing. at the C/S ,
Exit under the tip . so are horizontal or perpendicular or square or somesuch . as it were .
---------------------------------------------------------------------------------------------------
Fairly Groovey . Almost a SV 11 airfoil. WITHOUT the Sheeting. so 1/8 in. or so thinner .
No adverse affecys noted . The Plank Wing Spit. ( same fuselage ) not necesarilly superior .
Which I had been bothering me. As THAT wing was built ( Likely go on the Long Mk XIV Fuselage )
So my scale ( ish ) eliptical wing has produced no discernable downside. Far as I can tell . thus Far .
Pleasnt to fly and the pilots not as nervous . Perhaps the Typhoon was nearer hair trigger .
------------------------------------------------------------------------------------------------------
Next task is to assemble a better ST 60 . No Mods Considered yet . Bar some good solid .016 lines in various lengths for both .
Not Scarey on the 65s , which the Patternmaster & Folkerts are decidedly crowded on .
A good paintjob covers a multitude of sins. But dont stand closer than ten foot, thanks . :-X

Looking real good! Glad you got some flights in

Hi Matt Very Nice models and good to see you got off to a great start and they flew well off the board.

Er Um . Is TWENTY EIGHT THOU Correct for the Ring Gap . :-\ ( Another was 22 . %#*@ Remote Control Blokes . >:( )
New one is .006 and other near new piston & ring is 5 1/2 or a tight six . Delving into their innards last knight .
So Two Good plus a near new Two Ring motor , and two candidates for overhaul or A B C Conversion .Of the ST 60 .
My Supposedly Marvelous Wierd Hopper Tank in the Typhoon was still somewhat fueled . Thus dosnt entirely empty .
Points to good economy onthe biggish 3 blade C.F. prop , and the need for a new tank .
Will try a Eather ish Tapered Type , as need intake clearance forward . And 25 deep rather than 50 .
Fed Well in the Air . Maybe I should just revise the chamber feed holes . Perhaps . Takea look anyway .
Reasemble the Goodest Used Internals in the same case as Id fitted new bearings . One must NOT take things for granted . Like Ring Gap . :-[ :-X
