Jimbo - I read this thread, because I am just now finishing a Goldwing 30cc Yak 55M. There have been what I would call "normal" and "minor"ARF-issues with mine, but not anything to write letter about. Purchased from TBM. Quality of covering and paint is 10+, IMO, parts fit VERY good, alignments right on the money (normal stab tweaking to match wings). Hinge blocks at every hinge point drilled, but, alas, EVERY one of them was not on center of hinge line, so replaced all with Radio SOuth Pro Hinges (flat CA type) since mine is e-power.

I know the 30cc lineup is later in their experience, and I think the Pitts you have was when they were learning. I'm glad you're keeping it after all the work - my bet is that it will fly very nicely and reward you for the efforts.

I'm not chiming in to debate or derail your thread - I just wanted to point out what I've found with their 30cc bird.
