While reading the l-o-n-g thread on the "Horizon FPV Antennas" I got to thinking about something. It was stated results on mods that were very different could be power from the controller. If you put four, new regular batteries in the controller you have 6 volts. When you use rechargeable batteries you only get 4.8 volts. So for you electronic engineers out there could that make a difference?
