VOLKSWAGEN Touareg 2.5 Dakar - Chassis
About this creation
Here it is - the chassis for my truck trial version of the notorious Dakar rally winner in 1/9 scale and R/C

Front 3/4 view



A look at the 285bhp twin-turbo 2.5 litre diesel inline five cylinder engine



The spare wheels - useful for coping with Dakar's treacherous terrain, the chains can be unhooked one at a time, or together (as shown)





The underside - look closely and you'll see that the differentials are connected to the driveshaft by a worm gear, giving no backlash (or a chewed gear :s). Combined gear ratio is 20/16 x 1/24 = 0.05208 - torquey :D. So torquey in fact, in a test with fresh batteries, the chassis drove up a 1 in 3 hill (30 degree inclined slope) at which point the rims began to slip on the tyres (probably due to the weight) before the engine gave out.



The suspension - two shock absorbers per wheel, the chassis can survive a drop of over 14 inches without anything breaking!

Front 1x stiff spring + 1x medium spring per wheel
Rear 2x soft spring per wheel





The bare, stripped out interior - the least a man can get.



Cheeky side exhaust



Battery box and PF XL Motor



IR reciever sits nicely on the passenger side of the dash

These beasties go well in the Dakar! You've represented it well here. Excellent drive train and it must be built extremely tough to survive a 14+ inch drop! Very Awesome :-)

Quoting lloyd meli i think yourcrazy for giving up on this that is crazy, this has soo much potential
I'm revisiting it soon in 1/11 scale, I promise it will be better

don't give up in building trial trucks just because the first few didn't work, it took me ages to get the first one to work. try to keep it simple until you think you can improve then keep leveling up, you WILL get better the more you try.

Quoting space potato 4 if you want this to be a trial truck i think the problem is the worm screws, they waste to much torque so that is when you look at professional trial trucks there drivetrains don't use worm screws and i would never use them. but the chassis looks strong and i'm sure it was a fun project to have worked on. shame it won't be finished, maybe you could revisit it someday.
Yeah I know, I did some research afterwards and realised how inneficient they were, the scale wasn't right anyway, but I don't think my talents lie in the truck trials

Well, you think this is a disappointment, but I think At least you broke through at the following stuff: 1: Scale model 2: Creative construction ideas/solutions 3: Pics are superb! 4: The PF's are placed with lots of balance 5: Etc. I think of The A-team when BA and Murdock were on an abandoned area and they had to build a buggy from wood (including wheels I think) and remains of another broken down vehicle.

Sorry to disappoint, but I've abandoned this project. It was too heavy to get up a hill with even half the bodywork on, I tried it and it broke a universal joint in the back and a 12 tooth gear INSIDE the front differential. I tried smaller wheels and increased the ride height but the worm gear just ended up getting chewed under the immense weight trying to get over anything more then 2 inches high. I'm now working on a NISSAN 370z

Looks great so far! What about to try to support your models with some system bricks; like a mixed technic and system LEGO model, as I did on my Nissan Navara? That would be awesome . Any way, what ever you planed; I can't wait to see it ;-)

This chassis is great. I can't wait for the outer body. I think it would be amazing if you built a brick built body on top of this.
