Hello, do you have any tips on lining up the one-way holder on top of the clutch, so it turns concentric with the starter shaft? I had my heli assembled with the starter shaft spinning freely, only to find out there is drag on the starter shaft when I put the crankshaft in some positions.

Is there a particular engine you recommend for this airframe?
