You may not believe this, but the ONLY time THINK I have had one of my Futaba R149DP's go to failsafe instantly was once when I had low voltage on my battery. And that was weird, the engine servo was the ONLY servo that went to failsafe . It would bounce back and forth from idle(failsafe setting) to wherever I had the throttle set. It was almost like a warning or something. But on approach with the plane within a hundred feet I had full throttle control again. I have never felt complete loss of control though, if Im getting hit I have never felt it with PCM, but I have felt it on the same channel at the same field with a ppm rx (Channel 53).

Does anyone know for SURE if what I am saying is true, will a Futaba 149DP put the throttle only to FS in case of low voltage to the rx?? I know it happened but I could be wrong as to the cause.. ??
