Video: Futaba Team Driver Ryan Lutz on Throttle Expo

Ryan's radio is the 4PKS-R and one of his favorite "go-to-" feature is Throttle Exponential. Ryan navigates to the feature in seconds with the use of the jog dial, then proceeds to show how easy it is to adjust settings with the + and -- buttons. Positive settings increase the speed and strength of response. And as Ryan points out, going negative helps slow and smooth response -- a huge handling advantage in for nitro drivers on a loose track.
