BFB buggy upgrades with differential

Because a plastic gears in original project can not withstand a lot of load from the 540 motor, I have made some modification for a chassis and insert the Feiyue differential. And now the buggy is standing full power but a suspension arms needed to reprint from SBS instead ABS.
See my video with test run:

This modification still uses the original plastic gearbox, which I made from PETG, and its connect to diff by Feiyue driveshaft. Also I used Feiyue driveshafts for a rear wheels and edited a rear hub model, because the wheel axle too short for two bearings.
