Mini Rally Racer

Hello Everyone! I'm back with a nice little MOC that i built a couple days ago. I actually first built it last year but never had the time for pictures, so I rebuilt it from my memory. It has rear wheel drive via one buggy motor and 20t/diff gear combo. It has all wheel independent suspension-since I wanted the front and rear width to be the same, the rear isnt double wishbone. It's extremely light and has servo steering. All powered by one of my 10 volt batteries. I had to use some interesting bracing techniques in order to connect and strengthen the whole car with as little pieces as possible, but I couldnt find a simple enough way to brace the front suspension to the chassis so in a hard crash the front axle may come off. Pics: ^it gets quite dirty after prolonged outdoor use the front bull bar (same one from the 8048 buggy set) bends inward during a front end hit, so it definitely helps protect the car if it loses signal from IR receiver: In order for weight saving I used flex axles, which give a nice tight grip around the battery: Money shot suspension showcase ^when resting the rear suspension has neutral camber, when it is raised it has slight positive camber, but when leaning into a turn and it compresses, it has negative camber, which can actually help handling a bit: overall it has good ground clearance for its size, which allows for good performance on bumpy asphalt and light offroading, but for offoading it relies on wheel speed rather than low speed torque driving outdoors and through fresh rainwater puddles eventually collects dirt and water, which can get into places where you don't want it... ^but luckily dirt will fall of after a good shake once it has dried and water, as long as it is fresh rain/streamwater won't ruin motors/connectors, only pool/saltwater/grimy water will mess up motors, but I made sure the battery stayed dry And here's some burnout/drift shots: my new desktop background: ENJOY! -

I've refined this model many times and this is the final version. a simple buggy powered by two medium motors rear wheel drive with diff its pretty fast and does alright off road a simple modification to the design could allow for an xl motor to be put in and geared up. in the model the steering rack sits in the slot at the front of the vehicle and connects to the 1x6 links and the two 1x8 axles connect in the front to form the tube body frame. i also couldn't find the ir reciver it attaches to the pins that are on the roof of the buggy and hangs upside down and inside the frame work. other than that its complete. buggy.lxf
