FOR SURFACE USE ONLY     The new SR4S remote control is the basis for every model fan who prefers to operate a joystick rather than reach for the steering wheel and is also the successor to our incredibly popular "SR2S" 2-channel stick remote control. The lighter and slimmer design ensures that your hands won't get tired even on longer trips. In addition, the 6V (4* AA) operating voltage reduces the functional weight by 40%!
 

Equipped with the following standard functions:

• Servo Reverse (the direction of rotation/switching of the individual channels can be changed using this function)
• Trim-Function for throttle and steering (setting the throttle neutral position and straight-ahead running)
• ST. D/R Function for setting the servo travel limit (steering servo only)

There are also channels 3 & 4 for free assignment, which can be operated via 2 toggle switches.
