Actually, the wing may fold before the rubber bands let go. He says "reinforced", but I don't see anything, except what looks like a stock wing with a stock lite-ply spar and cheap chinese wood ARF construction underneath. The rudders look like they might flutter off, but you could probably survive that. You may NEED rudder control, though, to guide the wreckage down after the wings pop off, being that the ailerons are attached to the wing and will leave when the wing does.
