Fixed Joint is not so fixed??

See http://www.splatsosoft.com/unity/

Hold the 'u' key down for a second or two and the heli will rise. Let it fall and hit the deck. Notice that the skids are bouncing around. I'd like them to stay put, how do I fix this? The tail is also attached with a Fixed joint and when the heli gets moving quickly sometimes it starts bouncing also.

Thanks!

Instead of using fixed joints, have you tried making the skids and tail children of the helicopter body?

 

Ah OK, I was using too many rigid bodies. I set the skids and the tail to only use colliders and parenting now and it works great.

Thanks!

 

Yeah, fixed joints suck. instead, use a hinge joint with very small limits, like 0 and 0.0001. If you want to add a realistic "slightly shaky connection" factor, you can set the limit to something like 0.01 instead.
