If your engine turns counter-clockwise, you want your collet to tighten clockwise. If it's coming loose, there's something else going on. Have you considered a square drive?

Hi Peter, Welcome to the forum.

If the flex shaft is coming loose I imagine it an issue with how much you are tightening the collet or a problem with the cable itself. Use the correct sized wrenches (not shifting spanners etc) to get a good grip on it. Also be sure the flex is clean and dry where it enters the collet. Where did the cable come from? Realistically I cannot say I have had issue with cables coming loose and I have motors making more power than a Bonzi BX4.

It sounds like a problem I had. I lost a few new cables with the props at a race. I finally narrowed it down (almost too late) to a bad collet insert. It was just loose enough no matter how much I tightened it with the wrenches it would throw the cables. The collet would grind down the cable just enough to set the cable free under load.
