I recently installed my 10G radio in a backup plane that i had a Spektrum system in. When i turn on the radio, two of the Hitec-high torque servos vibrate like crazy until I move the stick, then settle down. If I move the stick again same thing happens. This only occurs on two servos, so I pulled the two out and plugged back into the spektrum system, no shaking and servos move fine. Any thoughts as to why this only occurs on with Airtroncis system????
