The motors I am using are DC gear motors. I have been controlling these types of motors with a wired PWM circuit. Radio control is just something I haven't learned about. Figuring out where to install such components would be very helpful at this stage of my build.
Thank You,

So if I'm reading you right, that's eight motors total? 4 Sabertooths would do the trick. Each dual motor control has six DIP switches to turn mix on/off for for/rev/steering - controlling two chs, with it off the 2chs operate individually of each other. Another switch for lipo cutoff or not, another is acceleration ramping, ect, I can't remember them all off the top of my head, but the instructions & wiring layouts are listed on the site for each device.
The 2x12 (for example) means 2 motor controllers with a max amperage each of 12A.
Yours lights or sound on/off could be controlled easily enough with either the Battle switch or a Pico switch, also listed on the Dimension Engineering website. Detailed manuals for each device right on the website.
Plug & play with very little set up.
I like the 2x12 I'm using for the swing on the JD850, very smooth! The only trouble I have on occasion is sometimes the swing creeps left or right b/c exact neutral sometimes changes, usually happens when I push the controller to its 12A rating, like when I lift the tracks with boom then swing, a more effective way of steering than making the tracks work against each other.
