Get to know your Dirt Master
A hands-on project for drivers who enjoy building as much as driving. Its rear-mounted motor puts weight over the driven wheels, while adjustable suspension gives you room to experiment as you learn what works on loose dirt and gravel.
Suspension you can tune
Double wishbones, adjustable turnbuckles and oil-filled shocks let you work on ride height and wheel alignment as your driving develops.
A proper buggy drivetrain
Full ball bearings, a rear gear differential and an adjustable slipper clutch are included. The slipper helps cushion sudden drivetrain loads.
In the box

Is this ready to drive?
This product is an unassembled kit. You assemble the chassis, prepare and paint the body, and install your separately purchased electronics. Ask us about a Parkflyers prebuilt version if you prefer to start with an assembled roller.
What should I check before the first run?
Follow the kit manual, glue the tires as directed, fill and build the shocks, and check that the drivetrain moves freely. Set steering travel, calibrate the ESC, check radio failsafe and confirm gear mesh and slipper adjustment before driving.
Does it already include ball bearings?
Yes. Full ball bearings are standard, along with the rear gear differential and adjustable slipper clutch.
