I'm happy with a 12.25x3.75 APC and the stock muffler on a scaled up PBF.

12x4 APC works great too. Havent tried an ultra thrust, i hear they add a lot to the top end but you loose some throtle responce, might depend on what prop you use. The mouse can you can tune to your needs. Leave it just a bit long and your throttle responce will be good.

Default 11.5 x 4 APC

I fly my H9 Pizazz/ gms .47 with a 11.5 x4.

Hovers all day long...and climbs out with comfortable authority.

I didn't quite get the RPM's I like out of the 12x4...even though it pulls nice....throttle response and top end suffered a bit.

Hope that helps!
