Did some testing this afternoon with the new Futaba receiver and put together a quick video of the first range test. I look forward to testing how far I can really go. I'm getting about seven and a half minutes hard flying. Was thinking about dual battery but I think that would just overload the motors. 7 mins is plenty of time. Video goes for just over 2 mins actual flight was 4 mins. I put in intervals of distance from google earth.
