Flite Spur Gear 48P 81T, Machined Delrin for EXO Spur ESC the spring loaded bottom plateHigh performance machined POM spur gears for all Exotek slipper eliminator hubs. These spur gears are 100% machined POM to insure true roundness, with extra interior machining to reduce overall weight for reduced rotating mass. Much stiffer and truer than molded nylon spur gears.
