I had the same problem with the TF Corsair. Just like full scale, I go around the plane each flight with an Allen key and check all the screws. After many years of service the wing bolts stripped out the wing inserts so I replaced them with brass threaded inserts. Now the screws stay in place better and have more holding power. I posted a photo of this on the TF Corsair ARF thread.
