Hi Guys,

I;ve just bought a sullivan dynatron starter. First time i used it on a conventional ccw engine the ali starter cone cup unwound itself and promptly flew off. I've refitted it several times and tightened the locking nut down but still it unwinds. Whats the point of having all this starting power if it cannot be transfered to the engine!?! I'm only using 12v and trying to start a webra 91AAR heli engine.

Does anybody have any tips to make the conventional retaining method more secure?
