If you're looking for speed or higher voltage options, consider a 1:50 gear ratio for better results. To create the freewheels, I've modified the original Lego axles and glued them in place using CA adhesive. In this current design, I'm utilizing a Wemos D1 Mini Wifi board and my own DIY motor driver to control the tank via the free RCWController app. Alternatively, you can also use an RC receiver and brushed ESC to drive the motors for a more traditional setup.
