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 h
