I have just been given an Aeronaut Race 400 . 7.2 volt,motor with attached ESC. This comes with just a Tamiya connection for the Accu and a JR connection to the Receiver, no switch. It was intended for Electro flight but I wonder if any of you know how to set it up and the swicth on procedure? I do not want to fit a battery without knowing how to switch it off!
