rc car and ultrasonic sensors

Hi there

I bought myself an arduino and have been re-educating myself with programming and have been scouring the internet of what others have achieved. I love the scooterputer and the wipeout game.

In my youth i used to race electric radio control cars and had a lot of fun doing it. I still have alot of my cars and equipment.

So i have been thinking doing a project for the fun of it but can't find anything else like it. What i want to achieve is to use an arduino with ultrasonic sensors on the car. The ultrasonic sensors will basically stop the car from driving into walls/obstacles as i drive it.

So my plan is to put one sensor on the front so it would slow/stop the car by applying the (electronic) brake. The car will also have a sensor on each side of the car to stop it from turning into something. The arduino will be located inbetween the reciever of the car and the servo/esc and will make the car run parallel to a curb/wall or slow/stop the car if its face onto an obstacle.

Now the cars are pretty quick so i understand if it can't stop it in time but can anyone see a flaw in my plan to stop it working?? such as processor speed, ability to handle 3 ultrasonic sensors, etc.

Any advice is greatly appreciated.

Thanks oscarcar, I did see that actually but its not quite how i wanted to go with it as i wanted to use faster, larger cars 1:10 scale and still have a large element of control from a radio, but it is the closest thing i can find at the moment.
