Hi
I recently rebuilt my tricopter, which is an aluminium version of David Windestal's Tricopter, with a KK2.1 control board, a 20a Q-brain ESC, a turnigy 2200mah 3s battery, some dt750, 10x4.7 GWS props, and other accesories. I have done some calculations, and i should be getting about 6 mins flight time, but im only getting about 2-2:30 mins off a full battery.
The batteries are old and have had a few cycles, I dont know whether it would affect the flight time though. I have thought about getting new batteries, although i dont know whether i should get the same batteries again, or get higher capacity ones, or get some 4 cell batteries.
Any help would be appreciated as I really would like to get some decent flying done and to hopefully add FPV before not too long.
