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.

As a one-time Lark owner, I agree that it would be difficult to
assemble the tail improperly. However the trim tab is very powerful
and the two solid wires which operate it are easily damaged. More
likely is the child yanking the trim lever back and forth.
