Hey guys


I have a DD with a 46 AX. What prop should I use? I tried a 8.75x8.5 and the tach said it was at 13,800 on the ground. I thought it would be higher. I know its not the best engine but it is what I have. Any suggestions?

That does not sound correct at all. that prop should be well over 15,000.

You should be able to turn a 10x7 at over 14,000, give that a try.

Thanks, I originally had the engine on my Twist with an 11x5 and it would really rev up. I will put the prop back on see what the rpms were.

I would see what that engine can do with a 8x8 prop. If it can't turn 16,500 or better, might as well save that AX .46 for 3D profile type planes. A piped .32 makes a nice combo on a DD.
