Ah, missed that you had a chassis already. I’ve got only got limited experience with Tamiya. A tt01 long ago. Didn’t really get the appeal it has to some.
If chassis is complete then sounds like you’d just need the electronics. Motor, esc, servo and receiver. Choices are wide open.
You might consider looking into used. You can find some great deals on complete vehicles, unusually missed controller. Touring car guys seem to change vehicles years. The new model comes out, old gets sold. I’ve bought a number over past few years with no problems.
