I took it to the field it flew great, DATA log said esc temp 150 that with 6s 12 tooth pinion the small one in the e5 kit that's canopy on over 5 minutes , could of flown longer battery over 3.89 per cell in batteries, ikon set up on gov. 1800, 1900, 2000 flew on 1900 most of the day 3d, setup on ikon. Flew fantastic its fast, loops great, roll are perfect like its on rails, did inverted power out was fantastic lot of power. Temp gauge at field was just under 100 and humidity 98%. The batteries are new I did not want to push too hard, batteries were just warm. I think everything is good, gear mesh is very smooth, I will set the gov. up a little more its under 80% in data I think its should be 85% but I didn't fly on 2000 rpm. that might help. I was having so much fun with it. I have stock gearing in the tail, so speeding up will help with tail, 540 were a little slow. I may just set idle 3 at 2300 like to get more flight time on her. Today has her first real flying. I very pleased with it. Great day when you go home with everything is in one piece.
