3 Channel Wheel Radio Question

[TOA57Y_27]

Just wanted to know if there are any 3 channel wheel radios with a 3 stage switch for the thrid channel for shifting. It would be goin in a race truck so no turn table servo is needed. Thanks guys

The Spektrum DX3R can be set up that way, and many older JR radios (R-1, XR3 (not the i model)) as well. The Z-1/KO Helios will also do it.
