Builder's Tip:

The HS-425BB is optimized for durability rather than extreme speed or torque. To get the most out of your gears, ensure your control linkages move freely without binding. Using the included rubber grommets and brass eyelets is essential for protecting the dual ball bearings from engine or terrain vibrations.
