Super tigre G90 speed prop?
 

Hi all
Hoping for a bit of help on this one, Ive put a G90 on a spad bulldawg, i'm not sure what prop to use, Ive tried the 13-6 and it seemed ok, Ive also tried a 13-10 but that seemed like it was a bit too much on the engine,
hopefully all you speed gurus can point me in the right direction.
regards
James

What is a spad bull dog? I would try an 11/11apc

RE: Super tigre G90 speed prop?
 

you could also try a 12 X 8 like I use on my F4 phantom or even a 12 X 9.. these props would also put it in the right power band..

I havent tached the motor for ages but when it was breaking in on a rich setting she was pulling 12,400 which isnt to bad:)

I 2nd the 12x9 or a 11x10 maybe??

12+8 or 9 is good for that engine.

on a bulldog I'd use the 12-9 and make a MCP for it, the stock exhaust REALLY limits tht engine. on my G90 I got a 1750 rpm boost on a 15-4 by using a MCP.

i have a g90 on a f5 tiger and im using a 13x8,,i have a mig 21 also with a g90 and im running a 12x8 on it. i have had good luck out of those size props on these g90s....i think the 12x8 is the all around prop for that engine.,,,you could also try a 12x9......i tryed a 12.5x10 but that was just to hard on the engine..
