With landing gear hanging down, it seems almost impossible to create a 0 up/down balance. The net effect of this is that once you put the plane in a knife edge, you not only have to keep feeding it rudder, but also a slight amount of aileron, because it keeps wanting to right itself. Combine this with a little elevator to actually get the plane to fly where you want it, and I have my hands full.

What plane are you talking about here? From your description it sounds like your model has a high profile rudder or perhaps a large counter balance on top. That will cause the plane to roll in KE, wheels or no wheels. If its a tall rudder or large volume on top, when applying rudder it will tend drop the opposite wing. Right rudder will drop the left wing and vise versa. Although dropping the opposite wing would roll the plane on its back, not right itself. As far as coupling goes, when it pulls to the wheels and elevator is needed that is different. I have one that goes to the wheels on rudder and havn't solved that as of yet. For me, it was best to mix it out on my radio. Slave the elevator to the rudder if your radio is capable. Its also a speed sensitive situation. Best bet is to fly straight and level and apply rudder. However the plane reacts it will duplicate that in KE. Good luck, Joe
