Turbo Timber flight times on the Graphene 4S 2200 cells.

Iíve flown my Turbo Timber with 3S 2200 45C Admirals, 1500 4S CHNL 100 C cells and Turnigy Graphene 2200 75 C 4S cells. The performance on 4S is the most desirable but endurance is not as good as 3S. The Graphene was tested and started out at 90 percent charged. Flying consisted of 5 max power climbs to 300 ft. 5 inside loops. 15 aileron rolls and 5 takeoffs and landings. This took a little less than 5 minutes using the DX9 power on timer. Total flight time was about 7 minutes because of power off glide times. Capacity of the Graphene 4S pack started out at 90 percent and at the end of 5 minutes was measured at 31 percent remaining. So 90-31= 59 Percent in 5 minutes or 59/5=11.8 percent/minute. If flying were to stop at 15 percent remaining then a total of 90-15= 75 percent would be used. This would take about 75 %/ 11.8 %/min X = 6.35 minutes. A 3200 4S 40 C pack has been recommended by Horizon and will be tested for similar endurance time.
