The Car that Climbs the Wall

Radio control cars have been available for many years and the manufacturers of these toys have been looking for some unique feature that would allow them to produce the “must- have radio controlled car”. That has now happened as the wall climber car has been invented.
The RC wall climber is operated just like any other radio controlled car, but it can do the unthinkable. The car can be driven along the ground and once it is driven into a wall, it will tilt and the car will be sucked onto the wall and then will be able to driven upwards, defying gravity.
The zero gravity radio controlled car uses the Air Venturi suction system. The basis of the Air Venturi system is based on the operation of a household vacuum cleaner. When the car is driven at the wall, it will tilt at a 45 degree angle. At that point the car has special fans which start and draw the car towards the wall by creating down forces. It is these down forces that keep the car on the wall.
There are additional skirts that fit around the car to make sure the seal of the vacuum does not leak; otherwise the car will not stay attached to the wall. The fans will only stay on while the car is climbing the wall, the fans do not operate when the car is on the floor.
If the wall is not smooth the RC wall climber may not be able to achieve enough suction and fall off the wall. It is best to practice on a variety of walls in your house to see which is best for the car.
The RC wall climber has rechargeable batteries installed so it is possible to get a couple of hours play time from each charge. The controller unit uses a nine volt battery that does require to be changed infrequently.
People who have purchased the RC wall climber have reported that the Air Venturi system that keeps the wall climber stuck to the wall is quite loud. This is something that may be more of an annoyance to parents rather than the children.
Due to the uniqueness of the RC wall climber, it is currently hard to purchase and even some retailers that do have the item in stock are reporting that they cannot guarantee a color choice as the demand is high.
