RE: Broken bell crank.
Yeah, the servo saver built into the bell crank I think over time will loosen up even after tightening it back up. I threadlocked the adjustable silver "screw" so it will stay in place. It's also important not to over tighten it, you will have to leave some slack for the saver to do its job.
i looked at the bell cranks again, opps i guess the left bell crank can't be used on the right due to it having only one arm instead of two on the right.
