not to distract from your thread cajungent but since we are on the same subject. I have a superstar EP that I converted to nitro from electric. I installed the nitro engine with the same exact down/right thrust as the electric motor...now, the plane is constantly climbing and I am having to give down elevator to make it fly level when I trim it out and land the elevator is down a good bit at center and it should not be that way. after talking to a few people at the flying club they determined that since it is now nitro powered and flying at much higher speeds I need to reduce the wing incedence ( raise the back of the wing slightly) could this also be accomplished by removing the down thrust?
