Default TRX-4 6x6

So last year I bought the TRX-4, ran it in one TTC this year and won another TRX-4 kit... I love having more than one axle but making the TRX-4 run 3 axles was a bit more of a challenge...
Past 4 weeks I was on bed rest from surgery, I won the kit 3 days before I went in. Once I was able to sit up and move a little bit I started building.
I didn't take many pics because I wasn't sure if it would actually work, I couldn't find anything on a 6x6 using TRX-4 guts.
I've made 6x6 and 8x8 with Axial but they are simple.
I also just recently got a 3d printer, I was going to make another MAN-KAT 1 but I made the 8x8 outta wood so I figured I would try a different body for this one. I went with a ZIL 131, mostly because I just liked the styling

I found if you extend the shaft they spin the same way, so I have 2 outputs for the rear and a carrier bearing up top

This one just shows the mock up of bolting a couple pieces or frame on place to extent... I later cut the extra TRX-4 frame and brazed it in place

Then testing the body height, had to trim some outta the floor boards to clear the transmission

Played a lot with a site called tinkercad so I could bring in the 3d files and manipulate them, adding things like the fuel tanks and resizing.

I finally decided on putting the ESC up front here, hood is held down with magnets

And the receiver under a magnetic lid back here.


And not sure how to make a video link work so there is a small and albeit crappy video of testing the drive line and shifters then the battery died

Still a lot more work to go, but it's a start.

Nice build. How did you make the extra output shaft on the trans?

50mm x5mm drive shaft piece from in my shed of random bits, not sure what kit it originally came out of. but it had a screw piece on the end as if it had a slipper clutch assembly at one point
