Ground effect on a 1:10 RC drift car: the XP2 aero kit explained
What the splitter, venturi tunnels and rear diffuser of the MMC XP2 aero kit do, a real test of the effect, and how to print them.

Can a 1:10 drift car generate real ground effect? The XP2 aero kit started mostly as a looks project. Testing showed the effect is there.

Looks first, then a real effect
The goal was both: an aggressive look and a working aero package. Mainly the look at the start. But as the kit was developed and tested, the aerodynamic effect showed up.
The proof is in this test on Instagram: air is blown under the car, and the suspension compresses because of the ground effect the aero parts generate.
The forces are not huge. It is a proof of concept, not a race wing.
What each part does

All three parts work the same way: they speed up the air under the car to create low-pressure areas, and that low pressure pulls the car towards the ground.
- Front splitter: the leading edge, which also fits the XP1.
- Side venturi tunnels: run along the underside.
- Rear diffuser: where the air leaves the car.
You can buy them separately or together in the full ground-effect kit.

When you notice it on track
Slightly, on high-speed entries on fast tracks: when you are accelerating down a straight and flick the car to start the drift. Once the car is sideways, the system is less effective.
Printing the aero parts
- Flat on the bed for the strongest parts.
- Vertical for a better surface finish, at the cost of weaker parts.
