Supertigre G21/.35 for a stunt engine????
« on: April 24, 2017, 08:11:32 AM »
      Any comments re using this engine to power a Stunt airplane?

                                                                          Tia.

   If it's the baffle piston version, it will work quite well. If it's the flat top piston, that is the combat engine, as far as I know. You might want to search that here. I have seen and heard several .40s and they did a great job.

Bob Baron used a ST G.21 .35 in his PA-8, which was published in AAM. One of the earliest examples of running a 2-2-2 with a 4" pitch prop.

But I wouldn't do it. It'd be like driving a Prius to the NATS and leaving the Bentley at home. LL~ Steve

Any combat/high performance single bypass engine with great flow and larger crankcase volume will have the same problem on a profile plane, which is flame out when you hit down elevator.

MM


         Have you ever looked at a combat model airplane? They seem to all have their engines mounted in a profile plan form. I have timed and watched MANY combat matches, and have never once seen any of them flame out on a down elevator input. I have used Fox .35 combat specials of balloon bust and sport models and have done the full pattern with them and have never had a flame out. I have run Fox .15,.19,.35s, OS .35s, .35FP .40FP, LA.40 and .46, McCoy .19 and .35,  all mounted in side winder fashion and have never had a flame out. Must be sumpin that you're doin' wrong.

Bob Baron's G21/35 setup worked well.  It seemed like the low-reving 2-4-2 guys didn't like his style one little bit. 
He also shunned the lavish fixation to score a few more appearance points and flew models that were neat but to not garish.
Maybe the stunt community's reaction to Bob was more of a factor than the success of his technology.

The rash of Nats wins with the K&B 45, ST 46 and G21/35 must have been a bitter pill for Fox 35 Stunt purists.

Not at all. I was merely suggesting that a Bentley would be swell transport to the NATS, which is always 2,500 miles away. It's the wheels of choice of all the big Rap Stars, you know.  ;) Steve

OOPS.



And HE called BENTLEY ' the Worlds Fastest lorry ' .  :-\

Anyway , unsilenced , a 21/35 with the supplied small ( 1/8 in. ) venturie , in a nobler Sized Sucker ,
growls round the schedule , with a exotic exhaust note , unobtainable from lesser engines .  S?P S?P

I agree with Howard, but if the st is a ferrari, then the Fox .35 must be a fiat........ LL~
