I present a little off-road experiment of mine. It's a large-scale model of the Soviet Ural 375D heavy-duty military truck, a truck I've had the pleasure of driving last year. The model's look is somewhat compromised but it achieved the primary goals, which included stress-testing the planetary wheel hubs, the new differential and my 4-speed remotely-controlled sequential transmission. I'm happy to report that none of these components failed and the truck, which weighs 3.94 kg, is able to drive over a 6 cm tall book or climb inclines slightly above 15°. It's not a perfect model, and it's truly sluggish, but oh well.

Functions:

• remotely controlled drive and steering
• remotely controlled 4-speed transmission (with the lowest speed disabled so I could use a PF Servo as shifter)
• remotely controlled pneumatical locking of differentials in all three axles
• 6x6 drive
• suspension: live axles #1 and #3, pendular axle #2 (for improved chassis rigidity and to maintain ground clearance)
• switch-operated rear winch
• opening hood with a V8 piston engine running at constant speed and opening doors
• and a tiny detail that I really wanted to get done: a see-through grille

This is amazing   It's also nice to see that the new parts handle all the torque from 4 hard-coupled L motors so well.

Wow! This looks incredble!

Overall a great build.  As with others, nice to see the new elements functioning well.  Thxs for sharing....

But I really like the above comment.  A while back we had a thread that asked something along the lines "when do you know a MOC or build is completed?"   I like this approach to building.  Since there is an infinite amount of tinkering that can be done, perhaps it best to begin with a few goals in mind, and when those goals are achieved .... move on.  If the goals are super-duper lofty, then perhaps endless tinkering is needed since it is required in the goals.  But if the goals are finite, succinct, and well-defined once those are achieved and don't know why one would not move on.  

 

Thanks for sharing and the honest appraisal; it's refreshing. It's also got some peak lego truck trialing era vibes about it, but with modern upgrades.
