A control system for a radio controlled model includes an onboard speed controller, an onboard receiver, and a separate transmitter unit having a throttle/brake trigger or other manually moveable member that an operator can move from a neutral position over a range of speed setpoint positions and a range of braking setpoint positions in order to input speed and braking setpoint information. At least one of the speed controller, the receiver, and the transmitter unit is programmed or otherwise arranged to produce a nonlinear speed controller response such that (i) the speed controller responds to an incremental increase in speed setpoint position of the moveable member near the neutral position with a smaller incremental increase in drive circuit duty ratio than when the speed controller responds to such an incremental increase in speed setpoint position near a MAXIMUM speed setpoint position (i.e., less throttle sensitivity near neutral), and (ii) the speed controller responds to an incremental increase in braking setpoint position of the moveable member near the neutral position with a greater incremental increase in brake circuit duty ratio than when the speed controller responds to such an incremental increase in braking setpoint position near a MAXIMUM braking setpoint position (i.e., more brake sensitivity near neutral).
