Ive been noticing that most reccomend a smaller diameter higher pitch prop for 3D and vice versa for percison. Can someone explain this to me? I thought the complete opposite would be true. Engine size I am talking about is 50cc. I was looking at a 23x8 until I saw on Troybuilt site that 22x10 is reccomended for 3D and 23X8 for percisaion.
Confused... Are we trying to keep down on torque?
