I've heard of that idea but never really paid careful attention to it before. Now that I'm looking for it, I see in the Wylam SE5a drawing (also shown on the forum link someone provided earlier) that the vertical fin is indeed off-set to the right!
That's the thing about going scale. If you're going to go scale, you have to go ALL the way!

Makes me think that maybe I DO have to somehow get more right thrust. BTW, something else that I haven't checked is whether there may be some slight degree of left offset on the model's vertical fin that could be adding to the problem. If there is, I can't change this now, but I could add in a click or two of right rudder.
