Product overview
The GEPRC GEP-Mark3 HB56 Frame provides a structural base for a custom multirotor build using 5-inch or 6-inch propellers. Its hybrid layout combines stretched-X front geometry with true-X rear geometry and replaceable arms. CNC-processed 3K twill carbon fiber plates work with 7075 aluminum parts, including a camera protector. A hood-style opening supports equipment access and replacement, while the camera mount has a 25° angle. The motor-to-motor distance is 239mm, and the stated overall size is 137*183mm.
Electronics integration uses a 30.5×30.5mm center stack mount, with a separate 20x20mm flight controller plate supplied alongside receiver and battery protection plates. The supplied configuration is a frame kit with plates, camera protection, pads, fasteners, straps and an antenna fixing tube; flight controllers, motors, ESCs and batteries are listed as recommended components. Two specification differences remain material to procurement: the arm thickness is listed as 5mm, while the included arms are described as 4mm; weight is listed separately as 107g and 200 g, without a stated distinction between those weights.
