3D model description

The vehicle I have designed was inspired by the OPENRC Project. I wanted to make it, but I wanted much more simplicity in the mechanics. I had a few DJI phantom brushless motors and various other aerial RC hardware laying around. I decided to go with these parts because I have never seen it done before.

Drivetrain:

The motors are built into the rear wheels, Eliminating Shafts, gearing, belts, and other costly linkages. The Result is a crazy fast, relatively high torque vehicle. (I am afraid to go full throttle as I have a relatively small place to drive my rc car.)

The ESCs( Motor Controllers) should be identical. I used different ones (one that is Simon K and one that isn't) and I got more torque from the non-Simon K ESC.

Steering and Front End:

The steering uses two 9g servos that simply are part of the Top A-arm. When the servo is able to move with the suspension, it eliminates the need for a complicated linkage system.

Wheels:

I should say, all of the wheels that you will need for this vehicle will need to be custom made. I designed and printed a road set and an off-road set. I doubt the wheels I used will fit anybody's tires. I tried to make the wheel versatility as easy to adapt as possible. For the Front wheels, a skateboard bearing was used for the wheel to freely rotate around. The rear wheels use the motor of your choice, therefore, the inner wheel diameter will differ with whatever motor is being used.

The Printed parts:

I recommend using a high density infill when printing your version(if you decide to do so). I used 20% infill with PLA and a crash destroyed every part in early development.

I used PLA for every printed part of the car, however, I wanted to use ABS, but I just cannot keep ABS on my heated bed.

Any transmitter should be suitable, just make sure that your servos are correctly mixed together to move in sync.

Building:

I included Screenshots as well as the assembly files from my CAD software to help on the assembly process. If there are any questions regarding assembly, feel free to leave a comment and I will do my best to help you.

ENJOY!
