i don't know the first thing about this dragonfly . it is the 4 channel model..
anyway for some reason the tail motor quit working,but if i put small battery to it ,it will spin so i think the motor is ok? is there some other thing that would keep the tail motor from working? all the connections are plugged in ok. oh, i can't find an OFF switch on the heli. so i plug and unplug the battery for on and off.
