Product overview
The GEPRC GEP-MX3 Frame, also designated GEP-MX3 Sparrow, provides a True X airframe for a compact 3-inch UAV build. Its 139mm wheelbase and 120*120mm dimensions define the physical footprint. The structure combines 3k carbon plate with a CNC-machined #7075 aviation aluminum fuselage, with a 3mm main board. Camera protection is incorporated into the aluminum structure, and grade 12.9 YFS screws form part of the hardware specification. The frame is equipped with LED taillights.
Integration provisions include 20 * 20 mm and 30.5 * 30.5 mm flight controller mounting patterns, fit for RUNCAM Swift Mini and Micro Swift cameras, a laser-engraved angle scale, and a GoPro attachment provision using a cable tie. Recommended build components are F3, F4, Naze32 or CC3D controllers; 1306/1406/1407/1408 motors; 15A-20A ESCs; and 3-inch propellers. Battery recommendations span 3S 550-850mAh through 4S 550-850mAh. These are build recommendations for the frame; the approximately 39 g frame weight excludes electronic equipment.
