Making Lego Car WIN Tug-of-War

How to win a rope pulling contest with Lego? I find out by improving a Lego car step by step and testing each version against the last. Things to consider: tire grip, weight, gear ratio, 4-wheel-drive, tow height, weight distribution, length, propellers. Enjoy! Tug-of-war rules: only Lego or Lego-compatible parts allowed weight limit: 500 grams tow height: no limit propellers: allowed The Lego wheel in the final version is 32020c01. It won a friction test https://youtu.be/cDpcdVf39kA https://www.bricklink.com/v2/catalog/catalogitem.page?P=32020c01 Non-Lego parts used in this video: CaDA Battery Box https://www.aliexpress.com/item/1005009447959720.html
