Driving a car on the ceiling
Released on: 2009-02-03

Someone driving you up the walls? Get some space and drive on the ceiling instead! In this episode, I show you how to drive an RC car on the ceiling.

What you need

Surfaces

The surface you drive on makes a huge difference to how the car is going to perform and stay attached to the surface. A solid surface like a fridge, dishwasher etc won't need many magnets to stay attached, and the smooth surface also won't provide much grip. Metal tiled ceilings are great, because it's much easier to balance the number of magnets with the amount of grip and ability to stay with the surface.

Tips

Keep the body on! It makes it heavier and harder to get the balance right, but it really really protects the car's breakable parts when it falls.

Remove as much slack from the wheels as possible. One of the problems I had here was the wheels effectively bowing under pressure. Once they were in that position, it was very hard for them to turn. Take a look at the "Wheels pulled inwards" and "Wheels pushed outwards" photos below.
