I grabbed one of these at Fry's, will get another. $10 each, 5.5" long treaded tank. 2.4GHz RC, IR shoting/detection, turret rotates, lights & sound: https://www.frys.com/product/9259299
That's 3 motors and a lot of hardware goodness! Says 8 tanks can play simultaneously. Good as-is for playing (Christmas gifts?) or hacking into an autonomous robot platform. I'll probably slap some Wifi FPV cameras on a pair. You DID buy some of those for $5 when I said to, not the current $12? :) https://www.gearbest.com/rc-quadcopter-parts/pp_212594.html?wid=2
Think these are the same ones:
"When you make a thing, a thing that is new, it is so complicated making it that it is bound to be ugly. But those that make it after you, they don’t have to worry about making it. And they can make it pretty, and so everybody can like it when others make it after you."
- Pablo Picasso
