Phone Carrying Car / RC Lego Racer

I have been working to create a car that I can use as a "spy" type robot. I decided to accomplish this by making a holder for my phone on the back of the vehicle and using Lego Power Functions to drive it around.

Tech Specs:
Power/Batteries: AA Battery Box with Rechargeable Batteries
Motors: Servo for Steering and M for drive
Control: Power Functions IR Remote/Receiver 
Instructions: Yes, Video
How it Works

This is the steering system. To the right is the Servo Motor that steers this car and near the center there are the gears that do the steering, Then that same axle powers a set of two gears with a 3:1 gear ratio to move the "Steering Indicator" so when you are driving you can see what way you are steering.
The motor in the back powers the differential.

That goes through a 3:1 gear ratio to the wheels.
