Max speed 178 kph, not bad. Power almost 950W max. Average 400W, the outrunner weights 70g and rated only 450W.
Currrent is alarming 68A peak, average 29A. My 45A ESC is quite hot after flight as ventilation is not good inside fuselage. May need a 75A ESC. Fullymax 35c battery is quite good to keep voltage above 3.4V-3.6V each cell.
Previous flight I accidentally use the wrong blade 45x41 for 4s and the ESC cut intermittently. Luckily the ESC I used has a separated BEC. Otherwise the BEC will shut down as well.
