Controls not connected seems obvious cause.


I looked at the local Lark after work today and I think it would be tough to swing the Horizontal/Elevator halves into place and pin them together without having the controls connected. Like any attempt at a fool-proof system I'm sure it is possible though. That doesn't discount the possibility of a problem somewhere else in the control system.
