Introduction
In the situation where the motor in a Traxxas Ford Fiesta ST Rally fails due to natural wear, lack of maintenance, or is somehow defective, the user may need to remove the motor and replace it with a functioning motor. The process will not take long and will only require the use of standard hex keys. This guide will provide a walkthrough of the process of removing the broken motor and installing a new one that can be ordered online or bought at a hobby store. Before using this guide, please disconnect the battery in the chassis and ensure that any dust or dirt will not pose a hazard to components before completing the fix. Any hazardous dirt can often be removed with canned air, a duster, or lightly shaking the dirt off holding the chassis upside down.
