PCM lock out servo mvt

[Wayne Galligan]

Ed,

I had a similar experience with the Futaba PCM reciever.  Only it took the rudder over hard and fried the servo.   Reciever worked fine and was even checked out at Radio South.    
I think the PCM receiver is supposed to hold the last know signal but for how long is a good question.

  Need some opinions on a JR system.  Thanx in advance

  Jr 10SX with a 955PCM rcvr.  The other day I turned off the transmitter and left the plane on for some reason.  I have the Failsafe set only to throttle to high idle.  All other failsafe channels are turned off.

  For no reason, the elevator servo went to full up deflection.  Once I turned the radio back on it corrected.  No one else on my freq.

  Today, while cleaning up, the plane was again left on, transmitter off.  For no reason L Ail full deflection up(nothing else) which returned to normal as I turned on the transmitter.

  Range check is well within range, and actually very good.

  Does anybody have any ideas to explain the above.  Am almost scared to fly now.

  Ed
