Hi all, I've started on the elevators and horizontal stab using piper plans via northland, I have almost finished the elevator with control horns and had a look at the plans for the horizontal stab and I have two drawings, 40643 with no control horns and 12769 with the stab shorter to have control horns on the elevator, the question is which one is the right one for a super cub ? or am I missing something?

Super cub uses the shorter one with the squared off end.

The J-3 that I trained in is set up with the non balanced elevator, that is what I believe you are calling control horns. I just finished up all my tail pieces except for the hinges. Have fun.

I haven't noticed on the plans ,but do the PA18's have weight in the elevators,,mass balance or are they just a control balance (horn)

No weight, just airflow balance.

The early Super Cub (90hp) had non-balanced elevators like the J3, PA11 and PA12. Bigger engines brought along wider, balanced tail feathers.
