In this video we do some outdoor testing of our Robak 2 and upgrade a few components including drive cups, differentials, tires, driveshafts and steering arms and then we finish off testing a few different motor/esc combinations with different pinion gears to find what works best.

The drive combo we ended up with was:
Motor: https://rcprinter.com/products/13-5t-540-brushless-sensored-motor-surpass-hobby-rocket-v3
ESC: https://rcprinter.com/products/10bl120-hobbbywing-120a-sensored-brushless-esc
Pinion: 17 teeth
Battery: 2S LIPO 80C 5000mah
