1) Attach bind plug to Rx (heli)
2) Turn on the Rx (heli)
--> Light blinking means bind mode.
3) Move sticks & switches to fail-safe positions (Transmitter)
4) Hold the bind button while turning on the transmitter.
--> Tx & Rx should bind after a few seconds. Light on Rx will be solid.
5) Remove the bind plug (heli)
Power off and back on if you want.
