TUG OF WAR! Lego Technic 42129 Mercedes-Benz Zetros Trial Truck vs 42099, 9398, 42114, 42099 6x6 4K!

Tug of war featuring the new Lego Technic 42129 Mercedes-Benz Zetros Trial Truck vs 42099, 42099 6x6, 9398 and the 42114!

This took longer than planned due to the 42129 drivetrain issues! Racing Brick did a video on the beam issue which comes loose and the 12 to 28 diff gears start to skip!
Not only that but the diff gear has quite a bit of play in it due to the locking differential so I had to place two 3 beams behind the differential to keep it from wobbling which also causes the gears to skip!
After that issue was completely fixed I noticed the driveshaft on the right hand side pops out of the differential gears so I had to make a 3.2 axle by cutting a 4 axle down!
After all that the drivetrain can take maximum torque without skipping at all as you’ll see in the video!
Please do not put your standard model 42129 through too much stress as you will break the diff gear teeth!
Anyway thanks for Watching and reading!
