[MOC/Mod] Trophy Truck "The Dawg"

Recommended Posts

This is the first non-contest MOC that I have posted.

It started out as @Madoca 1977's Baja Trophy Truck. I think I originally got as far as mounting the engine when I first started. As I only have the long shocks in soft, I decided I needed to redesign how the suspension worked. I also added all-wheel drive, which significantly complicated the front end. As well as kingpin inclination. I spent a good amount of time trying to get Ackermann geometry, but could not get anything sturdy.

That was almost a year ago. I shelved this project. Then my wife got me the Porsche, Claas, and a second SBrick.. And this is the result.

The main frame and roll cage are the most similar to Madoca's. Since I have taken these pictures, have redesigned how the battery boxes are mounted. They attach to the frame and sit much lower into the truck. It is possible to take off the bodywork and roll cage and drive.

I redesigned the rear axle so that the power sent to the front was from both sides, so that one set of l-motors was not power 3 tires. There is still some clicking in the front, but only when not driven on a flat surface. I had to reduce the gear ratio to 1:1.667. The differential at the rear acts as an adder and sends power to the front differential, and fake engine. The rear wheels are still driven directly by one pair of motors, each.

I could not figure out a way, without buying shocks, to suspend the rear axle on the smaller shocks and still have plenty of travel. Until I found some small springs in my junk drawer. I have no idea what their strength is, but they get the job done.

At full compression and fully turned, the front tires will touch the body. The body itself comes off in 4 pieces: each side, roof/hood, and front bumper.

I will leave you with my favorite picture

Very cool and very aggressive. I love the pic with everything removed showing the cage, the body looks good too. Well done! Any chance of a video of this thing in operation down the line?

Looks awesome. Especially like the rollcage included totally separate from the body. :thumbup: I second the request for a video.

Fantastic.  And everything is incorporated so well; the shot without the panels is great.  Guess you need to get going on that video now... :wink:
