My first flight was about 5 min in duration, after a few poor launches it was flying. Very slow but flying, trying to get the trims set was a real handfull and did not want to fly unless full throttle. Even at full throttle it was still very slow in the air. The videos I have seen were nothing like the performance I got out of the stock set up. I was rather dissapoinited with this RTF's performance to say the least.[&o]
