RE: Balsa USA Super Cub Build
selwyn,
The elevator servo access will be under a aluminum cover, the plans call them parts E and F, basically they are scale covers similar to the full scale Super Cub for access to the elevator jackshaft. Apparently the elevator on the full scale can be raised and lower on the ground to correct inflight trim problems. In my case the right side will be slightly larger to cover the access hole. The elevator is non-adjustable on the model. I hope this answers your question.
