RE: Dragonfly 22D i Need Help
The 9.6V NiMH battery is very weak and has very short flight time. I charged the battery for 2 hrs as instructed on the manual and hovered in the air for 10 seconds. After doing that for about 4 times, the battery didn't have enough power left to lift the helicopter. I was trying to trim the heli. A 11.1V Li-ion battery can extend the flight time.
