The preflight check of your model is a very important step that needs to be done. You can read about the crash of Suitcase's USL 120 in the crash forum under " Another US 12O Lite Bites the Dust" I was flying it over the runway and started turning right to enter a downwind for a righthand pattern to land. As the plane turned 90 deg to the runway it started heading nose down very quick. I pulled up elevator and it didn't respond. It went into some trees accross from the field. When we looked at it later the screw that held the servo arm on the servo was loose and the arm was off the splines. This model has the elev and rudder servos mounted in the tail and the elevator servo is mounted on the left side of the fuselage. This plane had a g-26 and it did vibrate so one little loose screw cause a crash. So don't forget to check even the smallest things because it will bite you when you lest expect it.
