Bought a Walkera QR X350 Pro, recently. BNF version. Bought a Walkera 703A RX, and the Devo7 TX. Can not, get it to bind!! Have watched video after video,on building and binding! None of the video's are quit right! But, I have pulled bits and pieces from each one, and tried different things. Unplug the power, remove the bind plug, power up again! Pull the bind plug out, while the power is still plugged in. Turn on TX, power up the quad. Power up the quad, turn on the TX. Bound and rebound about eight or ten times! No connection between RX and TX! Anybody got any suggestions?? Really frustrated!! Thanks!
