I built a DJI F450 Flamewheel Drone with a Naza lite flight controller and want to fly it with the DT7 Radio that I use with my other quad, a P2. I got through the build just fine but after powering the F450, the Naza lite LED will only light up red and it stays red. Also, I can not bind it to my DT7 radio. What am I not doing right? Do I have bad parts? Any help would be greatly appreciated.
