Er .

So, this ones the cause of the addled brain cells .

The 4 x 36 in sheet of 3/8 weighed 128 grammes , and still weighs that shaped .  with the cedar l.e. & t.e. . At least it shouldnt flex . 
This is the Super Nova one , its not so bad ,

That Supernova wing is LONG! I don't think the PDF that I have mentions the span. Just that you have to splice it if building from 36" balsa.

I've been "collecting" old Racer plans from the net but don't remember the "wing". What is it? Do you have a scan? I like the fuselage lines.

Hymph . Mutter . forgot the camera ( as this computors the public library ones ) .

Yea , the Span is 45 inches , 4 1/4 root chord , tip chord 1 3/16 .
Got the wing shaved and sanded to primary airfoil. Like to let it ease in and finish over a week or two , to ' stress relieve .
As in if you did one side of one side shaped and finished itd pull itself out of shape as you did the next .

Ive a drawing for a twin boom 60's place / harworth ETA 15 T/R . that I put the picture from ' the Rallies ' aside ,
and havnt been able to find for MONTHS .  >:(Looking in the old mags of ' engine tests ' I found two pictures from 63 of the plane
when it was just the ' NOVA ' same get up , bar front deck like a pan & wrap around windshield to similar but contured rear X section.

Ive put 1/16 ply one tips foor the streamline ' bullets ' / Gotta find a few things yet , Do a Bellcrank , but its pretty simple .

Dug this out looking for the Harworth One. They did a series ( this is Third at that Nats ( pic of finalists ) . ) I havnt a scanner ,
buttle photo a few blow ups of their 1/2 A and others . Be a bit frightening ina B . My first one ' glued into the groove ' so you
had to jerk the controls to get it to jump , say overtakeing - but was just built & flown . No medling with c.g. or suchlike .
Think it mustve been the RV so likely noseheavyish .


Dunno if these are  materialiseing , so will put the link here .

Wonders never cease ! link if you click on the picture will get it 50000 times the size . 

this ones a mystery . " 1965 FAI class racer by Gerry Hand of Ireland "
Must be a parrallel universe .

Bears more than a passing resemblance to Don Burkes GRMZYPH...

I don't remember where I got that photo... maybe some ACLN issue??? EDIT: Nope, it was "Classic FAI Newsletter 3" http://aerosports.net.au/LS/Classic_FAI_Teamrace_Site/Newsletters.html
I have another one of that model from John O'Sullivan (Irishman now in Canada), taken at 1965 Irish Nats.
I thought it resembles the 1963 Zolotoverch & Kobets model.

Racing 50s to early 70's style 2.5cc models seems to have some following in at least Australia, NZ and UK....
Plans for models of that time are available at "the usual free plans sites", and the thread I started in the C/L section on rcgroups - and of course many individuals who have them on paper.

some of the most classic and beautiful lines of c/l

Who needs plans, I still got the planes lol.

MM

Pictures, we want pictures {-)

flooged these from rc wo , Er . . .





To  keeps the peasants from revolting !  

Parent Kelly Machine . Some Say to be ' the best ' looking FAI  T / R built .
One thing here the blokes with honda engines in their Nortons get better economy m so real ( period ) engines need 10 cc tanks to give range parity .

Another Devious Scheme , Burning the Midnight Oil .

XFW aeromudle mag .

Dolgner , USA , 1962

Horton .

Lump on 2nd from lefts C Case Corner , V clever , we thought . at the time . Many Full Size aircraft , the cowling ' wraps 'the Cam Covers .

Nova Tip

Phil Staples N.Z. Record Holder ' B ' , ST 21/29 ABC FI . Not a City Slicker .

Don sent me a pdf of the GRMZPH ' B ' that ive recently had printed , Print shop said he would hold the scan for me, hasn't sent it yet .Will check .
Spoke to Mr Staples by phone in Wanganui several years ago . Ive been scribbling on a picture to ascertain dimensions . Should see if He is still with us.Im sure he said the span was 21 & tailplane 16 forty years ago !. Remember the paint wraps in a bead at the flat tips , so theyre
' boundary layer ' like a golf ball . 
Theres one other F'wing picture somewhere ( Horton , wonder if he's related TO Horten ?  ). Will do the Nova / supernova ones one day ,
One is ETA 3.2 cc in Supernova In ' B ' Finals at British Nats .
Fell free to ' borrow ' the printed pictures / plans .

Current state of play .

ok , fitting the BOOMS , 10 mm Dia. carbon tube , cut the 40 in length in half for accuracy of alignment . A Tip .
If you play Paul Robeson and put it on the bench , It comes out exactly aligned First time .  

 What a Surprise .

Next Morning .

This Saturday Morning , Mk III ETA 15 in the Boomer . Dual carbon 2 off 2 x 10 Dia booms .
That wings STIFF being built from a slightly HARD sheet of 3/8 .

The Mk IIIs a reed valve , the Mk III case has flanges to mate to a exhaust duct , to seperate the cooling & Exhaust ducts .
Anyone got any ETA parts of  K&B 15 Schnurle ( 1972 / 74 ) pieces or ' B ' stamped motor spare .

If its not there , it doesnt weigh anything . 

Seeing Classic A & B here ban Flying Wings , and B requires Two Wheels - we'll (  ) cover a few other options. Perhaps . Calculateing of the Combat G-15 & five minutes on 110 cc on 10% Nitro , a G-15 should give 30 laps on 30 cc. Or a G-15/19 for , as the wheels removable I can always upset the serius Speed Flyers with it ! .

Back to the Twin Boom 60's ' Wharfdale ' device. Id put the magazine with the photo ' back in the stack ' , and have given up looking for it after six months of periodic
searches .
Basically a replica ( we're trying , anyway ) of the original pommy one . Though inevitably we're getting a bit carried away with the cooling & exhaust  ducting .

The Ply theres the TOP of the Exhaust Outlet ' separator ' though you could turn the picture over . The Slot allows air up to the crankcase chamber .
Hopefully ' Feeds ' it up , if I figure where to put oulets to extract it to create pressure differential so its efficent .

i have a NIB K&B schnurle for sale

F Wing Tips.

in the Finishing.

And as mightve been ascertained from the prvious background ,  The Supernova Crutch .

A Side .

The F Wing .set up . The INTAKE there is purely to the Crank Case for Cooling .

Two appaling ( quality ) pictures of the 63 ' Nova ' ( pre supernova )

Na Na Na Na Nah na nahh .

Crank Case air outlet will be biufricated by the rudder, sort of a Stockton / Jehlick ' Jefe ' derivative .
The Dual Wing Fins might do the anti vortex trick , with a bit of luck .

Theres a picture in a old aeromuddler of a Eric Burden looking brat with a profile twin boom sea vixen catapult launch glider .
The bungy chords like youd use for a R/C glider and its reported to do 110 or 130 MPH . Stand CLEAR ! .

ST 15 RVD .

GRMZPF plan, reduced scale.

burning the midnight oil this week .

Rubber Band Powered . 

This Morning after an hours farting around .

Cowl Hold Down & Tank , Elevator sewn hinge , Wheel , Doping , F Glass inside top & Lower Nose todo before to morrow ! . 

Yea , found in winter pva combat wings built that week loosened up if flown that weekend in damp weather . Needed a week to harden up .  

Fibreglassed the underside or fuse & nose at 8 pm .And slapped a few more coats  of dope on later to keep the fuel out .

Finished it at 4 am ! Had ( another ) coffee , walked up to the car with the Twin Boom & Goodyear , put em in , turned round , And DAWN had Sprung !.
Two Hour Drive so at the field at 7 : 30 , hoped for an hours rest . But Someone else was there by 8 , most by 8:30 .

Left it in the sun to Harden up ! .

Mr Combat Had his American Fibreglass K&B SR Rat Racers , & a Gillott Rossi G/Y , as did Steve .

Pontificated about rotateing a backplate and carving a hole or two for the needle, crankey little suckers need a finger guard , though mostly its when you inadvertantly belt the END of the APC 7x6 .  

Elevator ended up about 3/8 UP & DOWN ,( actually 1/2 Down ) Had variously contemplated a few loops - a bit of inverted - on a full tank  . BUT She Grooves well , V Steady .
snapping the handle about didnt get it jumping , so stuck to level flight .

Quite Quick and steadyer than the DARA which pilots had complimented . Heres hoping ( hopeing ) a  long and usefull life .
Left the Top of the Fuse. Off both flights .No Sleep       so line of least resistance , after lunch .

Bounces like skippy ( the Kangaroo ) on landings - so needs leg teaking fore or aft .

Will rub back / flat off , maybe paint the fuse fins & booms . Leave the wings clear. My double heavy thread elevator hinge may be a bit overboard , so may redoo with the light hi - teck stuff ( thread ).
But MAYBE the turbulator effect and extra thickness is WHY its sateady as a rock ! .

I suppose theres one wauy to find out , Do It . 

Picture or two , doing a rework in a few areas due to the haste of the completion . Did I say it flew well.Cowless ! . 

Plugging a few holes butchered in the top deck , Set up the ETA MkIII reed valve ( Ayrldited the reed housing into the nylon backplate , LIGHTLY . As that was not biting on the thread  )

The Mk III and the Elite have the collector ring flange , that matches the hole in the duct , theyre machined circular there . Mk I & II the cylinder screw lugs raise ' through the floor ' ,
And the Floors NOT getting butchered to clear em , so only a choice of two. The Elite Comp. backs off , itll go ( back ) in the Goodyear with a Comp. Lock bar , which wont ffit this .
So its gotta be the Mk III .

now you know .

It is different from when I played with F2C.

Ive gouged out the goop on the booms , filler . as Id accidently used Talc & Epoxy , rather than the micro baloons , perhaps  .
Didnt save thousands of pounds  , its around 20 Oz. Came out a lot easier than anticipated , after months of contemplation , .
Big model knife , chisel for ends . 20 minute job . Although at that hour chronology maybe suspect .

Revised top set up , narrower now , using the P51 race canopy , angled . Nice Teardrop Contours topside .

And Frou .

The air from the intake visable there , top of three  , goes through the case bay , lowers'll be Fins , and Head .
Will have to get a groovey snapshot of the boomers outlets ,  .

To compliment the blurrey ones a few dozen up , Ive just found a real live photograph of the pre ' Super Nova ' NOVA , with the pan & seperate rather than fuse conture Canopy .

Turner / Hughes FAI "Mistress" ( 1864 I think ) .or a centurie later .



tho thisis labled as 68 , Has Same Number , I guess its the very same aeroplane .





Their other model is Zolotov Kobets ( or however you pronounce it ) more pictures there .

Amazing what a bit of red paint will do .


Out in the sun to long .
