Landing gear plate came off pretty much undamaged after only a slighly hard landing. Not enough glue. Re-inforced and epoxied back together. Flies great with 4250 motor and 4s 3300. 4250 is about 6mm to long but it still fits inside cowl. Very stable airplane. For the money a very good deal for an aerobatic sport plane. if you are big into 3d you might want to want to look for something else.
