The Robbe Race 3 PSW transmitter was introduced in 1979. Based on the Futaba brown box FP-T2F with same steering wheel and throttle mechanism, on first view the colour of case was changed now for black. A major change was replacing AM with newer FM technology, also narrowband operation was used now. New features were a small rotary knob at the top of the case for using different level of progressive steering and the addition of a 3rd channel. Maybe not that much neaded for car use but a welcome addition for race boats where you could use adjustable trim flaps now.
Still no servo reverse or dual rate functions with this transmitter, these were introduced with the Super Race PSW 4 years later.
