Hi guys!
here is my new project: the lamborghini cheetah, which was designed by MTI and made by Lamborghini for the US army but ... the hummer was a better choice ...

there is no good drawing of it on the net except one of tamiya.
So I used this one which I modified to be more like the real one, and enlarged to have a scale of 1 / 6.7, which corresponds to the size of the 2.2 Dick Cepeck Mud country tires and rims from rc4wd and the width of my frame!

the total length is 71cm (27.95"), the width is 29.5cm (11.6"), the wheelbase is 40cm (15.75") and the height is 26cm (10.24")
The frame comes from the remains of 2 buggys that I used for my zil 135, frame that I lengthened by 15cm (5.9") for the correct wheelbase!

The Rambo-Lambo!!!

It's amazing how everyone forgot about these. The HMMVW was a better choice, but i do kinda wonder how these would have done with IEDs and the uparmoring

Looks like a great start!

Excellent pick for build! Real-life story of this unique car is very interesting.. what happened to it, where is it now and why does Hummer resemble this so much..

I have original Tamiya Cheetah, let me know if you need some detail pictures of it.

Thanks guys, i really appreciate that kind words!

it's said that the lambo have a major default, an erratic handling due to the rear position of it's big chrysler v8!
thus, the trunk being filled by this engine, it is less practical to accommodate military equipment than with the humvee with it's front engine...

some progress

I made a high-tech mold ::D: to thermoform the headlights with styrene of .010" thick

next step, primer painting and putty, then final hood painting

I tried to search chassis pictures of it, but only found good pics of the LM002... Maybe there are some similarities in the construction style? But engine in the back is a big difference though :laughing: still I put the links to the pics I found.

And maybe you already saw all those but thought I'd put them just in case, they have a bit of detail even if you don't really see the chassis..

Fantastic. And well done on the headlights.

Thanks a lot ShopGTR!

Thanks a lot for the pics Frederik, i appreciate that!

The main problem with the cheetah is that it doesn't have shock springs or leaves, it's a torsion bar per wheel... with classic hydraulic shocks to calm the rebounds!
The frame is therefore different from that of the LM002!

The other problem with this cheetah is the tires! there're no rc tires that look like the special Mickey Thompson "run flat" tires!

Lots of detail pictures here!

Very nice shapes on that hood! About the chassis pictures, I understand now there are like only one two examples of this so that? I understand now why good pics are so hard to find!

I just randomly came across this 3D printed tire on tamiyaclub, you said you were searching for appropriate tires, maybe you can get in touch with that guy to either get the files and someone at SBG can print them? Or get him to do them for you.

While I continue reading the thread, it looks like the molded tires are a better option, since 3D printed ones are not very stretchable.

Hi guys :beerchug:

some progress

the rear of the body, made with 2mm styrene!
the rear where there are the red headlights is slightly rounded so I had to stick reinforcements inside to force the styrene to remain rounded

P1010073.jpg
P1010074.jpg
P1010075.jpg
P1010076.jpg

the front has been painted with primer and just needs to be sanded before painting ...
P1010077.jpg
P1010078.jpg

body sides are 1.5mm aluminum sheet with "U" brace
P1010079.jpg
P1010080.jpg
P1010081.jpg
P1010082.jpg
P1010083.jpg

the support of the rear of the body is also made of 1.5mm aluminum sheet
P1010084.jpg

next step, finish the underside of the rear part of the body and make the front and rear fire walls!
then the interior, then the roll bar, then the primer, then the details, then ...

Thanks Dagabba, 3 layers of filler and primer have removed the latest asperities!
Thank you for your research Frederik, I appreciate. Yes, I think 3D printing with flexible filament doesn't allow tires to be flexible enough and will lack grip ... I searched the internet to see if I could make a mold and use liquid latex but making the mold with the right structure of tire already seems very complicated and the liquid latex will not withstand abrasion on rocks and will also lack grip ... not easy to make tires like for example the super sticky compound of rc4wd!
