Another fpv tiny tank designed for lego tracks (x939) and 360 servos.

Wheels are designed to be directly screwed on to modified mg90 servos. For the free wheel a standard 3x8x4mm ball bearing can be inserted for reduced friction or use just a screw.

The top and bottom halves are designed to be magnetically connected with 7x4mm rod magnets but could also be connected with printed rods if you prefer.

Additional top servo for shovels or camera arms, includes a design file that allows a camera with 24mm holes to be screwed directly on the shovel arm.
