This is version (3) it uses n-20 drive motors and Futaba s3400 servos. for batteries I recommend these 3s models https://palmbeachbots.com/collections/batteries-chargers/products/copy-of-galaxy-3s-11-1v-lipoly-pack. This was designed in Fusion 360 and all of the non electrical parts/bolts were3d printed and tested before I ordered the armor panels from Send Cut Send. Just FYI the top panels are cut from polycarbonate, the armor panels are laser cut AR500. This robot didn't win much at Robot Rukus (in Orlando FL) but it's real tough! no one broke into the inner compartment, no one got close to my batteries!!! I think it's a great starter bot, great to learn how to drive!
