Did the H external antenna mod earlier today. Completed function check, short test flight. No range testing as I don't plan on going thousands of feet out anyway. I just thought it looked awesome and it should improve control connectivity having the antennas outside the fuselage. Only problem is the 2db 2.4Ghz antennas are 6 inches...way too long and they definitely are in the camera view when panning, so I'm waiting on the stub version of the same antennas to arrive. I'm pretty certain they wont interfere with installing Realsense or IPS module. Took less than an hour to complete. Warranty voided.
