GEPRC Mark4 7" Multirotor Frame
by GepRC

Product Description

Build a high-end, long-range aerial cruiser or a heavy-lift cinematic platform with the GEPRC Mark4 7" Multirotor Frame. Engineered explicitly to tackle the demanding structural challenges of larger 7-inch propeller configurations, this lightweight yet incredibly rigid frame features a low-profile H-shape layout that lowers the drone's center of gravity (CoG). This structural optimization enhances flight stability, improves tracking precision, and keeps propellers completely out of your FPV camera or HD action cam's field of view. Constructed from premium 3K carbon fiber plates coupled with high-strength, CNC-machined aviation-grade aluminum reinforcement standoffs, the Mark4 7" delivers industrial durability to survive aggressive freestyle crashes and harsh mountain-side landings.

The frame’s architecture excels in component protection and modular installation. It features independent, easily replaceable 5mm thick arms secured by a robust multi-bolt anchoring matrix to maximize rigidity and completely suppress high-frequency motor resonance. Inside the elongated fuselage, builders have plenty of real estate to mount multiple electronics stacks, with dedicated 20x20mm and 30.5x30.5mm mounting options at both the center and rear positions to accommodate heavy-duty 4-in-1 ESCs, flight controllers, and large digital video transmitters. Complete with a 19mm micro camera cage and integrated TPU antenna mounts, this legendary open-source frame layout is the gold standard for long-range FPV hobbyists, cinematic content creators, and sUAS engineering development platforms requiring ultimate mechanical reliability.
