V1.1 dies...

So after happily having V1.1 up and running for a few days, i decide to replace the tempremental dc motor used for steering the front wheels and install a little servo motor. This went very well... initially. I soon discovered that on startup pin 18 has some floating value until you set it. This caused the servo to try and drive round further than the stops of the wheels and rapidly burnt it out whislt i struggled to find out the reason behind its strange behavior. 

I am currently working on adding a pull down resistor on the pin to ensure this doesnt occur again, and am waiting on the new servo's to arrive.
