Mini FPV Tank

This is small fpv tank, inspired by https://www.thingiverse.com/thing:2896083 and https://www.thingiverse.com/thing:3013262. I created this mainly to practice at fusion 360.

The tank uses lego x939 treads, 9g servos, a 4ch frsky receiver, and a typical small all-in-one fpv camera. It's powered by a 600mah 1s lipo stepped up to 6v with a boost converter. There is also an arduino pro mini that reads in the receiver signals and controls the servos. While not entirely necessary since you can directly hook up the receiver and servos, it does let me control an rgb led, add a deadzone to avoid servo jittering when idle (by just floating the pins), and monitor the battery voltage.

The drive wheels have cutouts for gluing in cut-down servo horns. The idler wheels attach to the chassis with ball bearings and M3 bolts. The body cover directly snaps on to the chassis, and the turret attaches to the body cover via M2 nylon bolts (or just superglue). The lipo battery stays in place with a fric
