RE: Engine upgrade for Super Skybolt ARF?
[quote] No prop issues but 15" is the largest safe diameter with the standard landing gear so a 15x8 is the best choice. Also, the Saito has an 8x1.25mm metric crankshaft so you'll need a new spinner nut.
Ordered the 125 today, what size spinner nut did you use (short, long etc...). thanx for the help..
