mini Smart Robot Tank Car Chassis Kit Rubber Track Crawler Arduino 130 Motor

Great buy on a experimental Tank Chassis with motors! Works great with Arduino, Microbit, and ESP12E motor boards. I made upper body parts on 3D printer and found this item very usefull.

I was going to use this with a half track I was building. The track repeatedly fell off and get stuck and stripped the gear box.

This is my favorite small tank chassis design because of the great spring-loaded suspension, able to go over bumps. Other models, such as the small German panzer tank and the 8.5" narrow golden olive-colored tank, only have fixed wheels and don't have the good suspension. I haven't tested the treads out yet. This is my favorite seller so far, because of the great price, and because of the Amazon Prime delivery. Others take so long to come from China.
