Finally got the plane up. All was fine except 27 units of up elevator.
The front of the counterbalance was totally below the stabilizer.
We put some shim under the rear of the wing, a 1/16th"
It had no real affect on the trim adjustment.
Then we put in 1/4" of shim - no effect.

Plane balances fine and this is the only problem with it.
What is causing the need for so much trim?
This is my first plane with a counterbalanced elevator.

Thanks for the help,
