Power is what I'm looking for here. And the goal for this plane is 3D. The motor needs power and torque. I'd like to be able to hover and climb out (not just sort of be able to almost climb out). So odds are, the 46 size motors are out. A 50ish size motor is probably more what I want. Sounds like a 12X4 prop is the way to go. Thanks for the advise so far.
