Heli-Max Black Hawk Electric RC Helicopter Lot 2 Transmitters 2 LiPo batteries. I have both boxes and all the spare parts are still in the bags. One battery will not charge and the other works just fine. Both chargers work as well as both radios. 1 heli is 100% functional and the other has a gear drive issue for the tail rotor and would be good for spare parts. I bought these with intentions of getting back into the hobby, but time and work keep me from doing so.
