I have a Lanier Laser200 with a Fuji 64 (non ei) that range tests awesome without the motor running. Start her up, and with ant. collapsed it will twitch while standing next to it, walk away and it freaks out. Extend ant. and it only gets slightly better. My throttle linkage is a 2-26 wire with plastic ball ends on each end, so no metal contact with the throttle. My ground wire to the coil runs close to the throttle linkage though, could this be a concern? I also rattled the crystal out of the receiver while breaking in the motor, could it have damaged the crystal? The radio (Hitec Optic 6) works perfect with my 3 other planes. I have a powermaster dual battery system installed,and I bypassed it and still had concern. Any suggestions help, thank you all. Mike.
