hey, i am building a Great planes piper cub 40 ARF... There is quite a bit of play in the wing joiner/wing joiner slot, is this ok? or, what should i do?
Actually, that's fine. I have seen some tight fits that I had to sand a bit, to allow the wing halves to align correctly. You won't have that problem.
Follow the directions, make sure you know in advance how to align the wing halves and clamp them in place, and - as jrf says - fill the void completely with epoxy. Wipe off what drips out with a towel soaked in alcohol, clamp the wing halves in place (remember, you practiced earlier) and wait the required time for the epoxy to set up. You will have a strong, correctly aligned wing.
Good luck,
Dave Olson
