Now I am looking in RC-Switch which I think is for RC toys.  I read the following tutorial:How Radio Controlled Toys Work - Jff Tyson 2021mar30
https://science.howstuffworks.com/rc-toy.htm, and found that a full function remote control the following commands: (1) Forward, (2) Reverse, (3) Forward and Left, (4) Forward and Right, (5) Reverse and Left, (6) Reverse and Right.  I might also need to added more functions such as (7) start, (8) stop, (9) speed (very slow to very fast, perhaps in 10 steps.
