Well . . . ; its a Ginny , ( here ) and Miss Dara ( next ) actually . 

Super Tigre 15 and Eta 15 .

Wings are 1/4 & Fuse is 1/2 .Bout the 6th Ginny & third Miss Dara ive built , or will be the b3rd & first ! of them Ive Flown .

1/4" is too thin for the wing, use 3/8" and carve a nice airfoil.

You can paint 1/2oz fiberglass on with superpoxy after you fill the wood.

Cheers ,

5 hours  >:(with plane  , sanding block , 60 Wt.   , 80 & 100 , the Wings are shaped Fuse's just the rear top .
Two thick coats of Sig Nitrate . The Ginnys 165 grammes , wots shown .

Cheers , Im Doing a Shoestring 74 , for the OS 21 M for open here , so I'll have to fly it in RAT , whichll put to thick a line on it .
The 21 Mount pattern fits the Uctam 15 D , OS 25 FSR , G21    Maybe the H29R OS , almost . ETC .  so maybe it'll work .

N.Z. has OPEN ( 3.5 cc Good Year ) but here in Aus. its .15 .

Ive got a bit of the Glass Clooth , will be a First Time .  .
Dont think they have the superpoxy here , so intend to try EPIGLASS .
This is a Marine Product . The Paters Boats were Epiglass Finished .
Used AEROLITE structurally , though Alf Pinkers 40 Ft. Dual 350 Chev offshore  race boat / cruiser used Aryldite .
Dozens of One Gallon CANS of it . 
Kim Webys Chinese Gooseberry ( Kiwi Fruit ! ) Aeotearoa Teal Green & White suckers finshed with Epiglass two pack paint .
Reconed it took days to rub back , as its fairly hard .Maybe the Shoestrig'll get this ,I want to use the Gulf Oil Orange & Blue on that .

Wondering About using Carbon Vail on that , as potentially itd should go to fast to do loops !
Ive used good 5/16 wood for that wing , will taper it to 3/16 at the tips . ( theseare 1/4 all thru ) .
Have to find some Carbon Monofillament , so ' a trip to town ' is in the pipeline for supplies .

Ive Used the Hustead & Roy ' SPEED ' airfoil , as it seems to go o.k. 

My Fast G-15 is 50 Ft. Down in the Mangawhai Tip . ( note for horders & archeoligists .   )

running a RVD in the Ginny or a G20G with a Radu Head . ETA 15 for the Dara . so don't expect anything to exciting .
Ive put this on so other mugs can elicit the spirit of improviseation & press on Rewardless .
Often Solutions Jump Out as you progress - as necessary. One tends to get mentally bogged down in a mired of concepts .
' Pull your Finger out ' as the R.A.F. opined - and youre on youre way .

Got some fresh Aryldite from the building supplies . Now $ 61 for 200 Mls. Was $ 20 in N.Z. in 96 .  
Raided there SKIP . a pile of 5 & 6 in dressed short planks , a few rough sawn , and a thick 2 x 10 with a brokwen corner ,
For HITTING THINGS on . a Timber Anvill even . this is all Dunage / Scrap .

pressing on .The Nuts .

Ive used 2mm steel ( from the adjacent debri there  ) as Ive Found the 1.6 gutter Iron bends & the nuts misalign when overwound .
The soldering Iron didn't blow up . Aryldited to 1 / 16 lite ply doublers .

Plan 'B' .

this dates from 75 or 6 , from ' Galaxie Hobbie Supplies ' who bludged it off me . Must Copie & return to young Richard .

& C.

Did a quick clamp first on the Dara , And it held STRAIGHT when I had evolved the more refined assembly .

Wouldve been up the creek without those boards- so don't kick providence in the teeth .

Hope she gets finished and does what you want her to do.

She's all Tissue / epoxy coated , bar tailplane & elevators ,

Ram Air C'Case cooling & Cold Air Induction . can tape em up and see if theres a iota of differance .

passes the time , anyway . And the cheek cowl can earn its living .

Till Post Sunday then , 

Well .This is after the second race & a dogfight !. as I thought for a moment . U/C out and youll notice our new single bladed prop . one ' bullet hole ' ( 1/8 in. ) in the outer wing ,
slight gouge underneath the fuse .
the Aryldite / tissue finish ( reinforcing ) held up well . freebees Inc. a can of silver lacquer . that & the Black I have look like itll be a N.Z. colour scheme .  Temporary N.ers on it. There .

Looks Like RAY didn't get there . a fair ? turnout. 1/2 a dozen teams . We came 2nd . . . . last . on Heat Times . 7.49 I think . Had about three test hops ; roped Geoff potter into pilotage
which he said He enjoyed , and reported it Grooves  and behaves , bar wheels a little aft and a bit light on takeoff . Just as well I threw 10 grammes of lead in the outer tip < so Wt.s are - 10g.

Problems were a harsh Vibration - likely from the drilled prop - taipan 7x6 Glass nylon . and Comp backing off . So motor swap saw prop fouling . Phil Pool donated a APC 7x5  ( mono blade there  )
test run and we were underway into the call   for the race . First saw foul starts and restarts ,and a bit off exercise chasing the landings ,   then the front tank mount parted . Lacking rubber bands
luckily a strip torn off the flannel rag had it airborne through to the finish @ 7.49 . 

Next Race with the hot motor & a good start things looked good until at lap. 20 Geoff took on Steve in a Dogfight , for a few loops and a belly landing . 
a ' click ' He'd felt Earlier proved to be the pushrod washer . The notch & copper wire / washer retainer didn't . Rear Horn washer had departed too . . .
Mustve been the brain fade in the shed .
Bit of a gouge under & a 1/8 ( bullet  ) hole in the wing ( from the Landing Gear Wire - which tore out ) means she's in for paint & prep. Next . We Wont Rush This .


Was on the pace ( 27 sec. for Ten Laps ) straight off - and handled well . Still havnt been on the handle on one . Loops were sub. 45 degree , so looks like itd troop around on 60s for clowning .
Thought the low aspect ratio would get it mushing about . Glide wasn't marvellous .Over a lap out at shut off gets it short of the pitman .
 though I figure the 75cc tanks half the drag of the aeroplane . Rebateing it on any ' next ' ones if that big .

Not a Total Disaster , give it 2 / 10 . Geoffs pleased with the flight , so it'll do me. Still in 99/100 piece & cleaned , will ruback and spray a 21st century Black with Silver Kiwi colours Paint Job ,
And tidy up a few details . A bolt   through the belcrank arm to a 16G pushrod will sort that . Told Diesels Don't Tolerate soldered pushrod fixings . Was 3/32 wire . a bit heavy .

No harm done , but a ' shake down ' rather than a 10000 Pt.  effort , so far . Nice warm sunny day in the thriveing metropolous , will stall the return to the Siberian Climate . & see the seaside .
Largest There .

another.

etc

Wellyou are getting there.  At least you tried.

You can see where it tore out , and gouged it further back . Then where it  mustve hit . Bellied in in the bottom of a loop , sans pushrod - Trailing giving various elevator settings .

The Arylidite Epoxied H'wt. tissue maybe what held the show together .

Current state of the play . Id done the T.E. ' knife edge ' and it'd go all wobbly . So replaced with 5 x 1.5 bass .
The cut through the fuse went quite clean , Decided to leave as ' one length ' ( no join ) . Aryldide wiped &
masking tape over while it set seems to have it reasonably faired in . Have block sanded prior to epoxy,
Id pva'd it on , first . Your Rustoleum Primer , at this stage .
Gotta do a decent , removeable, undercarrage mount . Got some 3/16 mag alloy from choped Merc. engine covers
for the retaining plate . Pushrod & tank to do yet . Bolt thru the bellcrank now , loop & bush in pushrod end .

I had one of the Eta's with Steve Helmick when we were kids.....we never finished the team racer but we had the engine!
