Hello everyone, been busy with school but have still built many MOCs, some taken apart so fast after completion I never even took pictures :grin: but I have taken pictures/video of some, I'll start with this crawler I built recently. An xl motor on each axle geared down 1:3, Rok Lox 1.9 tires, 4 link suspension with LOTS of flex, low center of gravity, lightweight and long wheelbase all add up to an amazing machine :thumbup: :thumbup: its so lightweight it cant get enough grip to climb steep angles, unless its a surface like fabric, hence the crawling capabilities shown here: there is another video on my channel of the 'prototype' before my changes/improvements.

Took some links off for a new dragster idea with pneumatic suspension. Enjoy!

That's a very capable crawler, Max!  I like those RC4WD Rok Lox 1.9 Comp Tires on the Lego 44772 wheels.  Your cat is very relaxed during your testing of the prototype:

Nice, please make a video at outside. I would like to see how it acts on rocks. Keep out good work!

WOW!  Amazing performance.
Maybe it is time I put my RC motors away and start using my XL motors again.
It looks wide, but that makes it stable.
