We fly ours with a considerably lighter FP 20 and 9x4 APC prop. I shrunk a slight twist out of the wing. It is dead on now and needed no other trimming other than removing some tailweight I had installed. Easily the best flying profile we have on hand. Wings dead level at all attitudes.

With a heavier engine hanging off the side it's possible the overall tip weight might be too much but I'd look for a wing warp first. Very easy to shrink back out with a heat gun. Just don't get the seams hot enought to pull away.
