Kamaz Inspired Dakar Build - The Tekin K55
 

Earlier this year we finished the first Dakar rally truck build based off an M1079 concept, dubbed the M-55.

DAKAR Rally Modified Stewart & Stevenson M1079

The build was so much fun that we decided to follow it up with another. This one will be based off the Team Kamaz Master 4326 Redbull trucks. Just like last time, here's the concept for the Tekin K-55 Rally Truck.

To change things up a bit, I decided it was appropriate to go 2.2s and run RC4WD ZXL 5.2" military tires as the real Kamaz run 52" tires. The build sheet is almost identical to the M-55:

First order of business, duplicating the frame setup from the M-55 truck so I reprinted the center drop skid and battery tray pieces out of Makeshaper ABS.

Once everything was drilled out and test fitted, I started driling holes in the fresh cut frame rails and mounting all the pieces up.

Axle assembly was smooth sailing, Vanquish Products Currie F9s are a joy to assemble. All Vanquish parts and some Fast Eddy bearings to finish them off. Decided to go all grey underneath on this one since the truck is dark schemed.

Bomber trailing arms for the front and rear.

Axles mounted to the chassis with Incision Bomber stainless upper links. Servo bracket for on axle mounting.

Thanks! The last one was a lot of fun and drives like a champ, looking forward to making some real progress on this one starting next week!

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

Great stuff!!! Does the 3D printed stuff hold up to "moderate" abuse? What is the scale speed for the other truck build, about 8 mph? Throw a trailer hitch on the back, build a trailer and pull your Bomber along. Baller status. "thumbsup" Then the cost of building something like this, is it tipping the scales towards $2000-$2500 mark?

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

Thanks!

The other truck does about 14mph flat out, plenty fast for how big it is. The parts all hold up pretty well, I've jumped it, hit plenty of rocks and rolled it a few times. The cab will probably crack in a few spots if it were rolled over on hard ground a bunch of times at speed, luckily a little acetone and some touch up paint takes care of most small cracks.

Funny you mention a trailer, we are almost done with one for the 6x6 we built last year. Parts for it on the printer currently!

As for cost, I don't even know where to begin. Just the off the shelf parts used total somewhere north of $15-1600, then batteries, radio, receiver and all the time invested...Not even sure I can put a dollar amount on these!

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

Oh how I feel ya on the time. A little over 1-1/2 years to make mine test worthy, add another ~20 hrs or so for the body I'm going to do. Trailer fit the Bomber, or do you need to yank a 1.9 or 1.5 rig for it to look correct?

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

It's a bit out of scale. I plan to pull around the Vaterra Kalahari, it's just about proper size next to these big trucks.

tried to pm you
box is full

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

It's cleared out now. "thumbsup"

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

Some of the RC4WD goodies for the K-55. Mil-Spec ZXL tires and King shocks!

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

Its gonna be cooler than the last! 4200kv for real? Running 2s maybe?

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

Yep, 2S! I might have to try 2300kV on 4S though and gear it down.

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

You know the ESC would love you for it. I normally shoot for around 35k motor speed for a nice and peppy system.

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

These things are INCREDIBLE.
just saw the first one this months RC Car Action.
My jaw dropped so hard I think it hit the toilet seat.

AMAZING work here fellas!!!

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

Gotdayumit Ty!
I wish I had your free time.
....And a 3D printer. ��

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

is this for sale yet?????

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

NEVER!

Thanks! Hope to have some updates soon! Been pretty busy the last few weeks.

Thank you! They are fun projects, hopefully we will start having some cabs available for people to build their own versions.

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

Progress! Not a ton, but it's some. Got the transmission assembled and mounted in the truck yesterday and built the drive shafts. Decided to go 2300kV this time around and run 4S. Just need to drill the holes for the battery trays and then it's on to the shock hoops!

Re: Kamaz Inspired Dakar Build - The Tekin K55
 

Still working on this beast! We are printing out the panels for the cab right now, so hopefully in a few days we will have something that resembles a truck to show! Today I got the front bumper brackets cleaned up and mount on the bumper, then mounted the whole assembly to the frame rails.

https://scalebuildersguild.com/forum...0&d=1554926807

Cab hinge for some tilty action just like the real ones! Also mocked up the front shock hoops.

https://scalebuildersguild.com/forum...1&d=1554926807

Wheelbase stretched out to 437mm. The previous truck was 393mm. This truck will be quite a bit longer and wider than the first one!

https://scalebuildersguild.com/forum...3&d=1554926807

Mocked up rear shock hoops. Took some thinking and two revisions to get them to sit here since we flipped the transmission. I had to notch the gear cover for the right side hoop to fit where it needs to be. Since this truck is so much longer than the M-55, we will need a short carrier shaft off the transfer case to keep our driveshafts an acceptable length. Plan to use another transfer case output shaft, a super short WB-HD driveshaft and some printed plastic magic.

Still got TONS to do, but parts are coming off the printer pretty quickly (knock on wood) so it will start taking shape very soon!
