Fail Safe

[Tony Stillman]

Jerry:

The problem with Raiko's system was a bad Synthesised RF module that came with the tx.  I suggested that he get a standard module for it, and it is working just fine now.

  Wade,might try to contact Raiko Potter about his experiences. Lost two planes in a row -same radio, and all checked ok-.His went to full throttle both times -that was what his fail safe was set to. Don't know why but it was. Nothing found on radio checks-different switches/wiring in the planes. 
  Same Xmitter/Rx.,after checks, in my backup plane at Pensacola went to fail safe, but Lamar got him out of it by resetting in flight. Nothing found wrong--But has not had further problems with a borrowed Xmitter. Nothing found wrong with original Xmitter.
  Go figure--

    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.
