suzonka, You can peel the lower wing out without damaging the air frame. You can hot glue the stir sticks in without damaging the air frame. Try it. I keep bipes for different reasons, including the joy of bipe flight. But you might want to try a mono mod. I prefer the mono with stir sticks. Primarily because it keeps the keel of the plane in play. On a standard mono mod the upper wing flies, and drags the rest of the plane along. With the stir sticks you can force the energy back into the airframe. your call, Tim
