    ● improving the antenna gain on the receiver end is better than increasing the output power (except in rf-noisy areas). More tx power causes more issues with rf noise on your plane. 500mw is plenty of power! ● try to achieve as much separation of the vtx and r/c receiver as possible to lower the rf ...
