Range testing of my Black Widow copter with a 25mW 5.8G ImmersionRC transmitter, ImmersionRC Duo v3 diversity receiver, and CL/SPW and 4-turn helix antennas. The test was aborted because I didn't want to cross the Autobahn, and the wind was getting really annoying at altitude.
This is also the first video where I attempted to combine gimbal-stabilized GoPro footage with the ground recording of my FPV feed. The sync isn't perfect, something is wrong with the framerates on the videos - I got it as close as I could, though.
