Actually , got about ten of these suckers . The SuperTiger G-15 FI ( front induction ) Methanol Burning glow plug engine .
The most powerfull ( 0.6 hp @ 21.000 , 0.15 cu.in. displacement ) Hp per Litre engine produced.For Years
About 240 Hp per Litre . thats on Methanol / Castor Oil . about 4:1 ratio .
World speed record was about 145 mph in the .15 cu. in , - 2.5c.c. class around 74 .
'We' modified my new one to Miebach specs , same as the fastest at the F.A.I. worlf free flight championships , gives around 23.000 rpm .
'We' carefully ran it in .As it was ' a bit windy ' that school holidays , 'We' waited to fly it in the elliptical taped airfoil dogfight thingo ,
under ' unusual ' barometric conditions . The wind of the tasman coming over Auckland Harbour at a steady 60 knots = Gusting over that
somewhat . Lauched on the 52 ft steel raceing lines from the shelter of the macrocapra hedge , the funneling affect , and peculiar
aerodynamics spiting the thing out into holes in the air , pressures and centrifugal effects had it doing in the vicinity of 1.2 sec. lap ,
which equates to 180 m.p.h.
'One ' was obliged to maintain a firm grip on the control aperatus .
lines near to breaking strain ,going across downwind
Ordinarilly it would tow the sucker along at about 100 mph with streamer ( towed, for dogfighting ) or 105 plus later when ' NITRO ' became
redilly available in N.Z. and we added ' a dareing ' 10 % nitro to the fuel .
These things gave you a fine consideration of Time / distane as far as moveing things went . and taught you to keep the fingers well clear of the propellor
( Hand started , belt prop with index finger ) 'Misscalculations would stop the engine nstantaeneously from the 20.000 rpm plus, leaveing a imprint of the stopped propellor in the turf .Hose out & restart .Combat bout was 4 minute . 80 cc fuel , later 110 for the 10 % Nitro content increased fuel consumption .
The fatigue on the big end led to it throwing the area between the two lube holes , whilst slipsteaming itself at about 120 mph in a race plane.
The departed 'piece' fed itself through the ypass , mauling the piston skirt , then mutilated the head and scoured the sleeve . in approximately 0.3 sec before the remainder of the big end unhooked . And there was a sudden silence . :shock:
Fudge .
The Brothers engine was one of these .
sorry , thats the Glow. see Comp lever version below . Id sent off for this , was sent the Latest Version just out of the F.I. as the RV ' wasnt available at the moment , we hope youll be HAPPY with THIS ' ( shades of Ferrarri , who sent a old geeer in Aus. a 250 LM instead of the 250 GTO he had ordered )
A ' Diesel ' raceing motor . peak power about 18.000 rpm . Fuel Castr (oil) Ether & Kerosene . ( Kero Quality matters ) and Ign. improver ( D.I.I. )
A Fibreglass propellor . starting proceedure , from cold ) was , Flick. Clunk.Flick,Culunk. flick, Yang yang Yang .Observeing the digit the laceration ( clunk ) would eject blood sycronous with the pulse .A ' Finger stall ' or wrapping the two first fingers in tape , is ' the usual practise ' .
Got one of them ( given ) & a new case & spares , traded a FI diesel for another and given a third
( with the crank gone - can get new , $ 27 .0
pity C'do cranks arnt $ 27 :? )
THESE latter ones will be better for dog fights. Theyre a bit sturdier ( observe )
Theres a box or three more . New 21/46es , V-60s ( these dominated the world Champs for Aerobatic ( F2B for over a decade . And rowdey 21/29 5cc raceing glows and 21 /35 Dogfight deriveatives .Some late commie copies of the sextes ( 10 cc aerobatic jobs ) with aerspace metalurgy , machineing and fits .
Why dont ' WE ' do a COMMANDO like That ?
And all told a hundred odd f the darn suckers . Then theres a grands worth of the est timber in the country
and designs for god knows what thats ' a it advanced ' for the T.V. dinner set to grasp , these days .
Mr. Jaures Garofali, founder of Super Tigre engines
Thats a 2.2 horsepower 10 cc 21.000 rpm engine in his hand . He invented Aluminum ( silicone ) piston , Brass liner Chromed ( A.B.C. configuration )
Enabling those rpms and speeds of 200 mph plus , in 1970 .
