Russian MB-LT Army Surplus Logging Machine

This section is for builds that are not strictly Tamiya or Heng Long. For instance, replacing the electronics from a WSN or Matorro, or even a scratch-build.

I've always enjoyed watching these You Tube videos of ex-army tracked vehicles ploughing through the Siberian wasteland. Nothing seems to stop them. The MB-LT and it's variants seem to be favourites for logging and supply vehicles so seeing as I can't buy one I am having a go at making one.

No armaments, and a modified rear hull should give it that Mad Max look, and if I can make it amphibious so much the better. It should be an interesting project if nothing else! :/

LOL, trust you to find something obscure. How about turning it into a mad max machine, or a moon buggy to compliment one of your past builds ;)

I will be happy if it runs reliably! lol. Hopefully it will, I will use it as a mud plugging off road machine. :wave:

I am leaning towards nylon gearboxes as they will be immune to water getting on the gears and corroding them, but I may have to go the low ratio route. I can solve that problem when I get to it... 8O

Progress so far, it will be cut in half and the front and rear printed separately, I loaded the whole thing into Cura and it would take more than 5 days to print it. 8O 8O 8O

It's coming along, hours and hours of printing!

Wow, well done Rob :clap:

Looks like you have plenty of room for the electronics, but that sloping front looks like you're going to have fun fitting those gearboxes :think:

Fear not my friend, the gearboxes are a perfect fit, even the high/low ones, it's all in the design. :thumbup:

That was a funny video. This vehicle seems a bit heavy for civilian tasks... It may not have any armament but it sure does destroy everything on its way. This will be a fun RC machine, no need to fear something breaking.

The plan is to make it as strong as possible, designing it so that there are as few parts as possible. It's all done apart from needing a pair of short shaft gearboxes. I reduced the parts list to:

Rear hull
Front hull
Front upper hull
Roadwheels x 12
Idler x 2
Idler spacers x 2
Sprocket x2
Suspension arms x 12
Stainless suspension springs (bought them in 100mm lengths and cut 12)
Suspension spring mounts x 2
Panzer III/IV tracks.

It's all held together with stainless hex bolts, stainless washers and nuts, so can be dismantled if it ever needs maintenance. It also now has smaller sprockets. Once the Festive postal chaos is out of the way I can order some gearboxes, and get it completed. :thumbup:

Still progressing, need a pair of short shaft gearboxes to get it up and running, but before I can fit them I need to dismantle the whole thing and paint it. The best/easiest/fastest trick I know for 3D printed parts is plastic bumper paint. In the UK Halfords do it for less than £7 a can, and it is amazing for smoothing surfaces.

This truck is 3D printed and sprayed firstly with the bumper paint, and then a gloss coat. It's as hard as nails, I've rolled it down quarry cliff faces over rocks and hardly scratched it. It's silky smooth high gloss.

Looking damn good so far, we need more "late soviet" items to go with my TOPOL truck :D

Would be curious to do a test of just how strong the body is with the bumper paint/gloss though as I see alot of people take care of RC models as if they are super fragile wine glasses

The shell on the MB is 2-3mm thick, so it's as strong as it can be. I had to print the front and rear separately but they are glued and bolted together to make it all one solid lower hull. :thumbup:

Great looking build Rob, the crawler is very good looking too :clap:

Will this have the same electronics as your other builds with sound etc?

Sure, I rarely use RX18's nowadays, so I will find a TK22/24 with suitable sounds and run it with that. Of course, until I actually fire it up I have no idea if it will run nicely, though everything lines up and rotates smoothly, so it should do. The odd thing is that these don't have return rollers, my only concern is whether the plastic tracks will flex sideways on the upper run and detrack it. There is only one way to find out? :D

Just to prove it actually runs, though it needs decent gearboxes as these are scrap plastic ones and one of the final drive shafts is slipping like crazy.
