Planes will fly with broken hinges, covering patched with scotch tape or electrical tape, loose muffler screws, missing tail wheels, knicks in the prop, missing spinners, stickey retracts, and short antenna wires. Practice flying this way and you're flying junk and are looking for trouble. And if you are looking for trouble you are dead centain to find it. Get in the habbit of not flying until proper repairs can be made. Model airplanes thought to be in good condition can and do give enough problems from time to time to give anyone all the thrills needed on a seconds notice. Don't add to the percentages.
