You never told us, that I saw, what engine you were going to use. The bigger the engine, the more you need engine sidethrust.

Wing sheeting? I'd say no. Especially at this point. There is more involved than just slapping on some sheeting. It has to start and stop somewhere. Then it needs to be blended in at the leading edge. Then you may need cap strips to make it look right. Then the trailing edge is too thin. Then the ailerons, if used, don't fit right again. All this needs to be planned in earlier for best fit. My .02 anyway.
