When I turn on my transmitter I get two beeps, I fully maxed out (clockwise) the bottom pot on the back for range. Im not trying to fly vertically long distance but horizontally long range.At a height of 100 ft or so and a horizontal distance of 1000 to 1200 my wifi cuts out with no obstructions. I ordered the stage 2 antenna kit from fpvlr.com and I hope I can then fly out (not up) 3000 ft or better.
