RE: Picco P-zero 0.8cc
The cyclic torque (accel - decel) from compression and firing isgenerally greater with diesel. But if you are only turning 10k on thediesel, any size prop will be strong enough. Just don't be surprised ifit fails. Be careful about inspecting the props after landings and the prop arc while it's running.
The APC 4.1x4.1 I have has a nice strong root. It's not an E prop.
