Re: Russian ChTz T-800 1/16th scale Bulldozer model

Here's a view of the drive motors and how they are mounted. The grub screws were used just for holding the sprockets in the correct position while the roll-pins were drilled and driven in. You can...

Re: Russian ChTz T-800 1/16th scale Bulldozer model

The big T-800 dozer finally succumbs to field testing ripping loose rock. Appears a stone became entangled in between the bottom rock-guard rails and the RH rear sprocket while screwing the tractor....

Re: Russian ChTz T-800 1/16th scale Bulldozer model

Here's a link to the final field test for the big dozer. I think we were pretty well pushing it to its limits here. We wound the track speed back up a bit but it was a little too aggressive in rock...

Re: Russian ChTz T-800 1/16th scale Bulldozer model

Here's a couple of build pics.

One shows the frame detail. The other shows the completed sub-assemblies ready for final assembly. Of course it's been pre-assembled a hundred times prior, it was...

Thumbs up Re: Russian ChTz T-800 1/16th scale Bulldozer model

Glad to read of your success. I like the smooth action of electric actuators all the same. Like Scranton, PA and R.G. Letourneau, I'm going all-electric.

Re: Russian ChTz T-800 1/16th scale Bulldozer model

Thanks for the interest guys.

I made another vid. This was the 3rd field test so some differences are noticeable in relation to the 4th field test and walk-around.

Re: Russian ChTz T-800 1/16th scale Bulldozer model

Re: Russian ChTz T-800 1/16th scale Bulldozer model

This is a 1-16th scale model of the Russian ChTZ T-800 (T.75.01) bulldozer with tilt-blade and ripper. First, a little history. The 1:1 machine sits in between the D11N and D11T or just under the...

Russian ChTz T-800 1/16th scale Bulldozer model

I've completed the dozer. Here are the field test videos. #1 is a walk-around and #2 is 17 minutes filmed at a coal mine. Quite fitting since this machine was designed ripping and mass-dozing work.
