I found a Harbor Freight Neptune set for #09 27.175MHz with battery floating in the middle of a lake. I don't have the transmitter for it, but I'd like to get it working. I could buy a transmitter for freq #09 or I could convert the boat to work with my Specktrum DX6. The part that baffles me most is the Neptune has two motors, I don't know about speed controllers that work with two motor. Any suggestions?
