HI GUYS, I am new to elecric been in gas for 40 years or so . Question . I am told to use the same battery for the receiver & the engine told that the connection to the speed controller has to be seperated somehow as it can start up on one when you switch on the radio . So really i need to know about the wiring of the whole set up for the radio & the speed conroller. is it normal to have the eng/Radio on the same battery . scared the radio would quit before the engine & hence a crash ??? Thanks for anyones help / HURRI
