This radio is used in the world of r/c boating . Futaba is a great radio and easy to control. I have been using Futaba radio since 1982 and have had great operation and performance. This is the first time I have used AMain Hobbies and received great service from them. The radio system arrived a day earlier , that allowed me more time to install and test out. Thank you, Bob Muller
