[NSRCA-discussion] Radio Issue

[Eddie Batchelor P.D.]

Very interesting that you post this.
I recently had almost the same issue with my JR9303 and 770PCM Rx. Radio went into hold and crashed the plane( 2 horizontal rolls turned into endless rolls until it crashed .
new plane and upon take off had some down trim due to DEPS growing as the plane warmed up. elevator trim did nothing and finally I got on the stick -still nothing - then all of a sudden it pitched straight up.

called tony and sent him TX and both 770 Rx's. all he could find was tx power was down about 20%.  I don't know if that low power output cold cause the hold situation or not. Haven't put it back ina plane yet :-)

any help would be appreciated.

  Hi Everyone,

          I have a serious problem with my radio and I was wondering if anyone has any experience with this.


          I have a JR 10X that has performed flawlessly for 8 years.  It is 72mhz with a top JR receiver. Today while flying it went into failsafe mode twice.  It only faded for a split second and then came back. It never lost battery power, so I reasoned that it 's not the battery, voltage reg or switch. I assume it must be the transmitter, receiver or antennae.  I can put another receiver in it, but the only way to test is to put the plane in the air.

          How would I know if it is the transmitter?  BTW, range checking on the ground with the motor running turned up nothing. 


  TIA, Steve
