Which engine would be faster?
 

I'm finishing up another delta and have 2 engines to choose from, a GMS .32 and a OS .46FX. I have always used the .32 on my deltas but would the .46FX be faster? My experience tells me the bigger engine is not always the fastest because of RPM. I thought I should run it by some of you speed freeks and see what you guys think.

Thanks,
David

.32SX but they are discontinued now.... I'm not sure of the GMS .32 but I've had good luck with other size GMS motors.

Which make the plane balance better?

Not enough information to actually answer the question.

How large is the aircraft ? Wing area? Expected weight?

Since you have used the GMS in the past, what props were tried and what were the resulting RPM numbers?

I know that the 46FX properly set up and with the correct prop is quite capable for sport speed applications - that part of the puzzle I can provide.

He has another thread with the plane on it, very nice delta...
