The Poly-Tec 480-23 XL is a 2-pole very slim inrunner, which is equipped with a 4.4: 1 Maxon gear. Due to its speed of 2300 rev / min / V in conjunction with the 4.4: 1 gear it is perfect for turning large propellers with 17 or 18 inches in very light thermals sailors with a 3S Lipo.
With a 4S LiPo or 10-12 cells the motor produce about 750 watts. In this configuration, it can be used in gliders up to 3.5 m wingspan and 3.5 kg weight. The 480-23 XL is therefore used in light thermal sailplanes with very small fuselage.
