I am a new owner of a P3P and have been enjoying this upgrade over my P1. My firmware is 1.6.4 and 1.5.7 on the RC. I'm finding that at flying around an altitude of 300' I seem to be losing my RC connection around 2000' out, give or take. When I look through the forums and see 1+ miles out of a stock setup I'm wondering if there is an issue with mine. I'm aware that interference can play a big part in this but I'm disappointed that I seem to be losing connection at a short distance. Any insights would be greatly appreciated!
