I placed a bigger engine in my PW Extra and was having the same problem with it that I am having with the WH Edge. Today, I put a bigger propeller on my PW Extra and the problem has decreased considerably. I am going to order a new propeller for my WH and see if it fixes it. I really don't want to do anything to the engine/thrust angle.

ORIGINAL: Are you also saying that an AFT CG makes the left thrust moment of the engine more pronounced?
I did not do a thorough analysis, I just noticed that it was easier to make it go where I wanted with some added weight on the nose.
I flew the plane in an IMAC contest last October and did not do very well. Later that week I noticed that the 4 oz. weight I had added to the plane was gone, had fallen off, so I replaced it and tried flying my sequences again. It made a big difference, but I don't remember left or right, just that it mattered.
