Is this a Bad Servo?
Danny, I have an AW 260 with JR 8611a all the way around (except throttle). I have two Fromeco 4800 mah batteries going into a SmartFly Super Regulator then into a SmartFly powerexpander.
Sunday afternoon the throttle went to the fail-safe position so I immediately landed. Upon ranging checking, everything was okay. A few minutes later I decided to try to fly again but the elevators and rudder acted like low voltage.
Back at the shop I checked the output voltage of an aileron slot on the powerexpander and it was very low - 5.00 instead of 6.0 as it was supposed to be. Again when moving the sticks, the elevators and rudder servos acted like low voltage and when I measure the voltage in an open rudder slot found that the voltage dropped to around 3.3!! I had a spare super regulator and replaced the original and checked the voltage again. Ah ha, found the same low voltage at the rudder servo slot when activating the rudder!!
The elevators didn't exhibit this behaviour. So, could it be a bad rudder servo?
Thanks for your reply.
