It is powered by two L motors with a reduction of 1.191:1, with a differential and is steered with a servo motor. It doesn't get up enough speed to flip by itself, but hey, I did what I set out to do

Flipmobile by legomuppet9, on Flickr I was just playing around with my camera at this point
Finally, a short video showing the performance of it, I realised too late I hadn't filmed me turning it over and then continuing to drive, but I'm sure you can all work out that it can work both ways up
I present to you my latest MOC, a dakar rally truck. Dakar Rally Truck by legomuppet9, on Flickr Basically I made a quick chassis with full suspension, and then added a very simple and light-weight body to it. There's an XL motor geared up 3:1 and then an M Motor powering return-to-center steering. It has front independent suspension and rear I have-no-clue-what-it's-called suspension (please tell me, it'd be greatly appreciated) Speed and performance is good, it has just enough torque to get up to speed, so as it doesn't have a differential, it does lose speed in the corners, but this isn't really much of an issue.

I know this is a very simple MOC, I think I'm going to try a slightly more complex one for my next MOC, probably a construction vehicle. suggestions are welcome!
I have finally finished my latest MOC; a Rally Car.
Developed after my Supercar project failed, this MOC has the following features:
Fully Independent Suspension
Return-to-center Steering via an M Motor
Rear Wheel Drive via an XL Motor (geared 1:1 through a differential)
Locking Doors
Fake V6 Engine
Fully Remote Controlled
The Rear suspension is one I found on Youtube by Critycal Jess
It works pretty well, except the 12t Bevel gears transmitting the power into the axles do skip a bit when reversing/setting off making a pretty bad noise. But it is very compact for what it delivers and overall I am pleased with it. I attached an XL Motor onto the 24T of the Differential with a 24T gear, so the overall gear ratio is 1:1
The front suspension is the standard steered front independent suspension using the A
knuckle arms and Steering arm small (6571 & 6572 on Bricklink). The return to center steering unit is an adapted version of Sheepo's Type 1 (http://www.sheepo.es/2011/04/retun-to-centrer-systems.html) which then is fed to a gear rack 1x2 with ball joints (6574 on Bricklink) with an 8T gear. The result is a compact and reliable setup, also the same width as the rear suspension, which was lucky.
After developing the axles I then attached them together in a rigid chassis, incorporating the battery box, V6 engine and IR receiver into the design.
Then came, for me at least, the hardest part of the build; the bodywork. It took the longest to build but I am incredibly pleased with the result. This is the first time I have built bodywork like this in one single colour (apart from the door mirrors unfortunately) as it is the first time I've had access to enough parts. I am pleased with the shape and overall look of the bodywork. The weight is also pretty low too to help with the performance of the model and I like the "skeleton" effect by not filling in the gaps like the bonnet and roof etc, so you can see how everything is working, which I feel you should in a Lego model.
This is my favourite MOC so far which I have built, I am very pleased the looks and the performance, and it is fun to drive around and distress pets.
Update on this project, I am scrapping it. The reasons are because I simply do not have the parts or the skill make the complexity and scale of this model work. Instead I am going to build a smaller car without a gearbox but instead with the following functions:
Rear wheel drive via a XL Motor and differential
Front wheel steering via a M Motor
Full suspension, front independent, rear I have not yet decided, possibly independent I'll have to see
Fake V6 engine
Decent bodywork, as this wouldn't have been achievable on the bigger model with the parts I have
I leave you with some photos of the almost complete chassis which is as far as I got on the big model. I will now disassemble this and start building the smaller one.
