A friend has a Kenpro KR-400 rotor that has stripped a gear. I have tried to find a source of parts for Kenpro or for the KR-400 on the internet, but I have not been successful. Does anyone know of a parts source for these rotors, or does someone have a U.S. telephone number for the company? Are these the same as Yaesu rotors? Thank you. 73, Jan Ditzian KX2A kx2a@arrl.net
