I have often wondered why the swash and head linkage was not a better fail safe design. There is a lot riding on those connections.

I was thinking about a double link design with double servos stacked.

One thing is that I never use glue on any moving mechanical parts on my helicopters. NEVER. To me, all parts are replacement only.

I didn't put glue on any mechanical moving parts. Just where the servo extension plugged into the servo. I thought it might provide a small measure of safety. Apparently I was wrong

Mine fall down, went BOOM!!

I kinda of agree with the ball link thing. But another option that happened on a raptor 50 once wrecked it repaired and didn't notice anything wrong with blade grips, but on first spool up one of the plastic blade grips failed and flung a blade luckly it went away from everyone. and the remaining out of balance head folded the rest of the heli pretty good. So I would say something on head gave way weather it was a link or a ball. Most likely cause would be something came loose.

The rotorhead was from an Align LE. Full metal and completely gone through from the previous crash. The grips are still good. I am almost sure it was either a ball link popping off or the elevator servo came unplugged. Either way the damage was pretty extensive. I am in the process of putting it back together. Everything ball link related is getting replaced. I do however need to find a better way of securing the servo extensions.

when ever i put a servo ext. on I use a piece of heat shrink on it to lock it all together.
