Ok, so this is my DJI Phantom. That is, without the carbon fiber utility tray and extra battery mounted underneath: The specs are as following: 1x DJI Phantom 1x set of balanced Carbon fiber props 1x Carbon fiber Utility mount 1x QuadFrame Gimbal 1x ImmersionRC 5.8GHz 600mW Video TX 2x 2200mah batteries, one inside fuselage, one underneath mounted to utility mount. 1x set of ImmersionRC Spironet antenna 5.8ghz 1x FatShark Predator V2 goggles w. standard camera. 1x Futaba T8J Controller w. transmitter. Total weight including two 2200mah batteries: 1350 grams. My questions: 1. I get about 6 minutes of flight time. If I exceed this, it will come crashing down. Does this sound about right to you guys? 6 min flight time I mean for a 1350 gram DJI on 4400mah power? 2. Max range with standard 250mW Video TX was 730m in open air. With my new 600mW Video TX, the range is extended by one a mere 50 meters. Logically, the range ought to have been doubled. Is this because I am not using an external receiver for my FatShark goggles, and just using the built-in one? Is the built-in video receiver in the FatShark Predator V2 simply too weak, even though the video TX on the Phantom is strong? Appreciating any input. Sincerely, Alveprinsen.
