Do not try to fly this thing without opening up the wings and fixing the landing gear blocks. Apparently they were attached with spit. Went to the field and the first one gave up just taxing on grass. Fixed it and went back thinking it was a fluke and the other one was OK. WRONG! This one gave up on takeoff and cartwheeled the plane doing some damage. Do yourself a favor and fix these blocks before attempting any flight. You can cut the cover and reach inside without having to cut any wood to access them.
