A three blade prop will balance both mass and yaw forces. A two blade
won't. There will always be a yawing vibration with a 2 blade whenever
there is significant angle of attack. (Downgoing blade sees a different
AoA to Upgoing one)
End result is that in general 3 bladers are smoother than 2 blades.
imho electric is cheaoer than hydraulic but not as fast so electric is
no good for aerobatics.
