Hi,
Here is an RCArduino project in action, a 40km/h rear wheel drive car with Yaw Control provided by Arduino. All control over the steering servo and throttle is coming from the Arduino, its reading the incoming receiver signals and also a gyro to measure the rotation rate, its then using this information to generate modified output signals to keep the car from spinning out under acceleration and braking -

Big plans for this one, now that the system has proven itself I will be changing the motor to a race motor for the next test - 50km/h !
