MIXMASTER,

I have had that problem with my Showtime. I have laterally balanced it. I have adjusted the elevators so they are equal throughout their range of motion. Before I did this, they were not equal at all, and I thought I had found the source of the problem. Still, however, when using normal high rates or when trying to harrier, it has a tendency to roll to the right. It only does this when I put in a significant amount of elevator, so I don't want to mix in a permanent amount of rudder or aileron to offset it. Normal flying around is unaffected. I tried using small left rudder inputs to counter-act this tendency and found that it would start to snap to the left when I did that.

Now, if I come in low and pull full up on 3D rates and stand it on its tail, it does not roll at all.

Any advice anyone?
