Product overview
The EMAX E3 2808 is a propulsion component for larger FPV builds, with 1300KV and 1500KV options covering different operating priorities. The 1300KV version targets efficiency, long-range flying and endurance-focused cinematic aircraft; the 1500KV version provides a higher RPM range for responsive exploration and cinematic builds. Both specify 3-6S batteries and 6-7 inch propellers. Integration dimensions are 34.8 x 37mm, with a 5mm bearing shaft and 250mm, 18AWG leads. Motor weight is 53.6-53.8g without silicone wire.
Its 12N14P architecture combines an anodized AL 7075 housing, steel shaft and one-piece outer rotor with N52SH arc magnets, single-strand winding and an NSK precision bearing. These features address impact-related alignment, heat-related torque loss and high-speed vibration. At 6S, peak current and maximum power are 56A and 1410W for 1300KV, versus 65A and 1640W for 1500KV. The supplied configuration is one motor with five M3x8mm screws, five M3x10mm screws, an aluminum M5 nyloc nut, and a washer and shaft screw.
