Hi im trying to make a plane that doesnt have ESC , but has on/off and elevator and tail channels into an ESC on left stick and the elevator and tail on the right , now , The way I fiqure it, I already have a four channel receiver and an ESC that came with it , all I need is the radio . So , is it possible to order a four channel radio with a specified frequency , so I can match the receivers freq I already have ? Thanks for responding ,
