objective

design and build a tracked rc vehicle using mostly 3d printed parts.

prototype

a new law regulating the use of larger rc quadcopters is looming over rc pilots in switzerland. this made me think about how i could reuse larger brushless motors in the future since i have many heavy models that will require some sort of pilot certification nonsense. so i decided to disassemble almost all larger than 250 g drones.
the motors are not really made to drive rc vehicles unless an appropriate gearbox is used. so i designed a tracked rc vehicle that is driven by two brushless motors and a gearbox having a gear ratio of 32:1. This should produce enough torque to drive the model.

the following pictures show the partially assembled vehicle:

here’s a video of the finished vehicle:
