If you are talking about the .40 sized ARF (not the Wagstaff) the wings are glued together. I've got a .46 FX in mine and it flies great.

Do you have realflight? The plane flies very similarly to the one on the simulator. FWIW I went from my trainer (Avistar) to the GP Extra ARF (after lots of sim time) without a hitch. I've been flying it for over a year now (about 90 flights) with no problems.

It goes where you point it, but it is a very smooth plane. Go with the recommended throws and it will not snap out of loops etc. If you increase the elevator throws you need to be careful.

Good luck!
