I am pretty new at this hobby and still need some help, I just put together a mini 3d with a O.S. 25 fp motor and was wondering where to start for a prop? How will different props and pitches affect the performance?
I have some 8x4 and 8x6 APC props and I think I bought some 9x4 and 9x6 master airscrew props wwould one of these work or do I need someting else?
