Agreed, if you're carrying up trim to fly level, that translates to a pull to canopy in KE.
What's different is you mentioned a pull to the wheels when applying more rudder to maintain altitude. I find this strange (but then aerodynamics is full of surprises) as most designs have more ruder area above the thrustline than below. This means more drag above thrustline (resulting in a pull to canopy) and roll coupling (due to asymmetric "pitch" of the rudder acting like an asymmetric elevator ) causing a slight tendency to roll to inverted with application of rudder which is often confused with a pull to canopy.

I said :Jim, when I fly my electric I probably use rudder 90% of the time.I can tork roll it pretty well.The problem with my plane is when I use rudder in KE it pitch to the belly I did mix in a bit of down elevator to counter act but this plane is flimsy,when doing some rolling circle I can c the tail is twisted about 15 degre. Its ez all I have to do is had a bit of up elev when passing thrue KE,but I cant seem to get that in my head...hehe.Maybe I should try this with my UCD instead it would probably be "facile" hehe

I made a mistake here,the foam plane pitches to the canopy...hehe

I design and cratch built a plane back in 99 that doesn't need any mixing while using rudder,you can do a flat turn without using ail.I think its the shape I use for the rudder that causes that .Here is a pic of the plane U cant really c the rudder to get an idea .I'll go take a pic of the rudder and post it.

in a bit
