I have recently finished building a Great Planes 40 size Ultimate Biplane. I test flew it earlier today and I am lucky to still have it in one piece. After rolling into a right bank, the plane rolls left and pops up when I apply elevator. I don't know what it does when in a left bank and elevator is applied, I didn't get that far. I think that the elevators aren't aligned, but I really don't know. Any suggestions would be helpful.

Thanks

It sounds like your elevators aren't moving the same amount. It could also be a twisted wing, too much elevator travel, accidental mixing of the rudder or ailerons with the elevator or it cold be tail heavy.

What engine are you powering this bipe with???

check engine thrust alignment, you need 3 degrees of right thrust for an Ultimate in my experience
