Knife Edge Switch
I depends on how much elevator and in which direction you need. If it pulls toward the landing gear that is sorta normal. Try a flat turn just using rudder. If it also tends to drop the nose then you can program in some up elevator with the rudder. After programming in some up elevator in my DP 330L to get it to knife edge in a straight line I tried a flat turn. It doesn't tend to drop the nose any more. We tried the same thing on a Sig Sukoi and it didn't work as well. You'll have to try it. FWIW. I needed 2% more on one side of the rudder than the other.
