From our amazing Tech Guy Bobby:
The Drift gyro assist is a nifty device that assists you in driving and getting the perfect drift angles around turns with drift cars.
With offroad vehicles, the drift gyro system helps you drive faster as it keeps the vehicle running smooth through obstacles such as rough holes or inconsistent terrain. Hitting dips at an angle would pull the car away from its intended path and a late counter steer steering input would have you counter steering all over the place and spinning out when you initially just wanted to go straight. With the assistance from the gyro, The steering automatically counter steers calculating your angle attempting to keep you going straight.
This is how you install it: (As you get better remove it and improve your driving skills!)
Remove the steering servo plug from channel 1 from your reciever box.
Plug that steering servo into the gyro box.
Plug the gyro box into your reciever (channel 1)
Center your ST TRIM or adjust it so that the front wheels are tracking straight
Mount the gyro so that it is sitting upright. Kind of like this guys car http://www.hpieurope.com/graphics/wa.../w_8442_02.jpg I like to mount it on the center chassis plate on the center of the car. It protects the device from crashes like when you smack into a curb.
Test the device by shaking the tail end of your truck left and right. You should be able to see the wheels counter steering. If it doesnt, you plugged something up wrong or mounted the device incorrectly.
