Improve Xpress Mini drive efficiency with Factory Pro FP-O-DB3171

The Factory Pro FP-O-DB3171 Low Friction Drive Belt is built for the Xpress Mini and features 57 teeth and a 171mm length to match the original fit. The construction focuses on lowering internal drag to help your drivetrain run smoother and last longer under regular use.

Benefits of a low friction belt

In competitive RC use, reducing drivetrain resistance makes a noticeable difference. A low friction belt such as the FP-O-DB3171 reduces load on gears and bearings, which can improve throttle response and decrease component wear during frequent running.

Basic fitting and care

Fit the Factory Pro belt so it tracks square on the pulleys and avoid twisting the belt when routing. Check belt tension regularly and inspect for fraying or glazing to keep the system operating reliably.
