Binding Procedure:
1. Put the binding harness into connector location marked BIND.  Next apply power to the receiver.  Receiver LED should illuminate it means bind is accomplished
2. To set fail-safe throttle and control surface positions, (minimum throttle and all control surfaces set to neutral is suggested). Press and hold the bind button of transmitter (LED will illuminate), Turn on the transmitter.
3. Receiver LED will change from rapid flashing to slow flashing and a few seconds later when bind is accomplished the LED of receiver will illuminate solid. All fail-safes should be programed correctly now.
4. Remove binding harness from the BIND channel.  Restart the receiver by cycling it power off and turn on and connect battery into BIND channel is recommended. All channels should function properly now.  You may test fail-safe by holding sticks in corner, cycle transmitter on and off.  Surfaces and throttle should return to your preset fail-safe positions.

Only one bind procedure is required on a new receiver.  Repetitive binding provides no extra security.  Always remember to remove the binding harness after successful bind is completed.


LED Indication:

  • Solid illuminated Red LED is indicates good signal.  If flashing, 1 flash indicates 1 signal loss, 2 = 2 signal losses and etc....
  • The Orange LED on main receiver should flash one time when power is first applied.  It will flash several times when binding harness is connected.  It should stay illuminated if main receiver losses signal but the Satellite is still working.

1x REDCON CM621 Receiver

Customer Reviews

Great, and very compact receivers, at a great price!! Review by Doug Johnston
Small, light weight, good range, great pin-out setup. Bought two and tried them out on some foam planes. They bound well, and worked well. Range check good, could fly planes at far edge of sight with no problems. I liked them so well that I ordered 4 more. As stated, they are DSM2 only, but not a problem for my particular radio.
