A few months ago we released an Digital Metal Gear Servo for the cars. The part number for this new servo is 1RC7017 and is listed on the website. This servo is an upgrade for the cars and works really good for racing.
If you choose to use this new servo in your car, make sure you order the Solid Servo Arm as well, this is needed for this servo, the stock servo saver on the car will not fit this servo. The part number for the Solid Servo Arm is 1RC3011 and is listed on the website as well.
The combination of this servo along with the solid servo arm takes a lot of play out of the front end and works really good for racing.
