RE: Best/Fastest Plane for a Moki 2.10 !?!?
ORIGINAL: ckombo
It has to all depend on max thrust. The greater the force the greater the speed. That is just basic physics. I read online where a user measured the thrust from 10 different propellers on his .46 and found a 12x4 to ''pull'' the hardest...I agree that there is a balance between size and pitch obviously, but I dont understand how a shorter but higher pitch prop is always better...
You do accelerate as long as thrust is greater then drag. The 12x4 may "pull" the hardest on the ground but so does first gear in your car. However, it is not good for speed as already mentioned. A shorter prop but higher pitch is NOT always better. It has to match your airframe and what you want it to do.
