Many thanks for your response!

One thing really worries me. You said "If you build it crooked it'll never fly right". There is actually an issue already. The kids epoxied the wing halves together (in this kit, the wings came prebuilt and pre-covered) in such a way that they are not exactly aligned. One is at maybe 1/16th or 1/32 of an inch angle compared to the other; that is the front edge of the right half is raised and the back edge is lower by that much. This is a fairly big model, I'd say the wing is about 4' long, so we're hoping that that 1/16 or 1/32" of twist won't make much difference. There's no way to undo it now, so if it is absolutely not going to fly right it would be helpful to know that now before we spend more 10's of hours on this kit. We can chalk it up as a learning experience (be much more careful!) and try again. We can use the transmitter, engine, etc. on a new kit, I assume, if this one is already destroyed.

Thanks again!
