minn flyer has it right. I've used kit supplied horns for years and they have until the last 3 or 4 years been fine. But as stated above the cheaper kit makers have tried to maximize profits two ways. Cheaper hardware and repeat kit sales to replace the crashes caused by the cheap hardware. When I obliterate another model I always salvage the hardware if it is an older model and didn't cause the crash. My crashes are very seldom caused by a hardware failure except for the nut that holds the control sticks on the radio.
