I've got a new GP Fokker DR1 and am mounting a OS.91FS. The amount of right thrust that is built in to the firewall appears excessive to me. When I called tech support at GP they did not have any data on what should be the norm for this plane. How do I go about measuring the "correct" amount of right thrust (and down thrust)? What is the effect of each? Does the fact that this is a tri wing aircraft effect this calculation as well?

Happy Flying!
