Greg, did you try complaining to the company? A warped wing is totally unacceptable. I have an old plane I built years ago that a warp crept into, and I'm surprised that it flies quite well, but I wouldn't accept an ARF that way.

Yes, the wheels look small for grass; I plan to substitute 2 3/4 inchers. I'm used to wire LG, but I may bend my own slightly shorter gear. It looks longer than necessary, and even more so with bigger wheels.

I'll check for pushrod binding; thanks.

Jim
