Fail Safe

[Wade Akle]

Lance, if the switch fails there is no power to the receiver. How can it go to fail safe?

  It's painful to hear your story.  Happened to me before too.  I lost a plane due to a switch that appeared fine on the ground but didn't have enough "clickage" to maintain it in flight.  Another due to a broken wire inside the insulation.  With the system on, Roll the wires between your fingers and look for a defective wire in the power path.
  Sorry,

    Need some insight...
    Using a JR10 radio and PCM receiver. Plane in a vertical climb at full power. Lost power pretty high in the sky, plane did a tail slide and flipped to a straight down line. No response. Noticed that the engine was not stopped but idling. It took between 6-10 sec of a straight down line until it disintegrated on the runway.
    Immediately thought 'fail safe' which was set to idle and neutral controls. 
    Battery and switch checks did not show any obvious problem. 
    Interference is unlikely due to the long elapsed time w/o any response as well as a subsequent Frequency sweep check which did not show any spurrious signals on our frequencies. 
    Transmitter voltage well above 10. 

    Any ideas on how to isolate the cause? or just junk the receiver and even the transmitter as our previous experience with repairs on intermittent problems are not encouraging.
