One of the gentlemen at the field I began flying at showed me a small trick that does work. Put 8 rubber bands on, 2 on each side front to rear, and 2 on each side crisscross to each other. Carefully hold the leading edge of the wing on one side of the fuselage, and use the other hand to hold the trailing edge of the wing on the other side of the fuselage. Now, with some moderate effort, push / pull on the wing, and if the bands are not holding sufficiently, you will feel the fuselage "slap" the wing. Add as many in the same pattern until the wing and fuselage "stay connected" while performing this operation. I failed to do this, and like you have seen, the fuselage and wing did separate some, with the wing losing alignment at the end of the manuver. This caused the aileron to jam, causing a spiral that I couldn't get out with opposite rudder. Fortunately, I shut down the throttle before it did it's final spiral loop and caught a dirt facebath. I have used the technique since then, and have not suffered any from it. Also, check the bands out every time you refuel, that can catch you by surprise also. Of course, the best mod is putting the nylon screws in, but you may have to find a unique way to make the front of the wing stay latched into the fuselage. It's not that tough. Good luck.
