I can't believe that you would even try to fly the plane without taking time to make sure to use thread lock on all of the set screws on the plane. If you would have done that you would have noticed a missing set screw. They have two holes on there gear, but only use one screw. I took the time to file a flat spot on the gear and installed another set screw in the empty hole and have not had one single problem with my gear. I have dealt with Horizon many times and they have been super. I feel it is your responsibility to make sure the plane is safe to fly. You are the pilot in command and the responsibility is in your hands.
