Prop Question
 

Cam anyone recommend a good prop for a .46 engine on a pipe? need more thrust than speed right now it a 10x6 on it now.

APC 11.5X4 - fast spin-up
APC 12.25X3.75 - Maximum Thrust

Thanks for the reply cvfd59... I'll give them a try..

I have run both and personally like the throttle response of the 11.5x4. The 12.25x3.75 is a heavy prop.

Depending on how strong your .46 is you might want to try a 12x4. I have not tried this prop, but have read on RCU where some people get better response out of it than the 12.25x3.75.

Thanks for the info cvfd59..

If you want high thrust, but also to retain a reasonably good speed, get a Bolly, or an APC 11x6, or an 11.5x6.
It will get 13,500-14,500 RPM and will make enough thrust to pull a 6 lb. plane vertically.
Speed will be close to a 10x6 at higher rpm.

You may need to lengthen the pipe/header, to get it into tune.

If the pipe is tuned to a APC 10x6,I would use a APC11x4.You want a prop that will turn the same rpm'sas the 10 x6
