RE: APC Props?
well, i don't know about apc being able to spin at higher rpm. I have an ASP .46 on my venus and I put an 11x6 MA on and then an 11x6 APC. I was getting ~1500 more rpm with the MA. I know that may seem like a big difference, but I could clearly hear the engine rpm revving higher with the MA and the tach confirmed it. I'll definately be repeating this though. I do notice the APC weighing much more than the MA prop, which I would think would lend itself to spinning more slowly.
