Checked my angles today; based upon the assumption the stab is at zero, and it appears to be so, the top wing is near zero with one side at a minimal twist in one direction and the other side a minimal twist in the other direction, probably due to the wing struts. I can easily take care of that. The bottom wing is about two and a half degrees negative!! The front of the wing must be raised about .60" to reach the zero angle. I suspect the wing dowel holes were not off location after all and didn't need to be elongated...it's the saddle that needed the alteration. This is ARF #36 for me and of all those before it, no matter how badly they had been, this is the first one that needed a wing angle correction. As you say, the belly pan will need extensive re-work and the struts and associated screw holes will also need alteration. I noticed Tower Hobbies no longer lists this model on their web site. Hmmmmm.
While I'm at it, I'll check the engine vertical thrust angle and its alignment to the stab. That should be interesting, considering...
