GEPRC Mark4 7 Frame Kit

GEPRC Mark4 7″ Frame Kit

The GEPRC Mark4-7 is a premium 7-inch drone frame engineered for pilots who demand a balance between long-range stability and freestyle agility. Crafted from high-strength 3K twill carbon fiber, the frame utilizes an H-type layout. This design choice provides a balanced center of gravity (CG) and ample internal space, making electronics installation and maintenance straightforward.

Durability is at the forefront of the Mark4 series. The frame features 5mm thick reinforced arms and high-quality Alu6061 aluminum standoffs in a sleek titanium finish. Whether you are cruising through mountain ranges for cinematic shots or performing aggressive maneuvers in open fields, the Mark4-7 offers the structural integrity required to protect your high-value electronics. Its geometry is specifically optimized to minimize “prop wash” and provide the smooth flight characteristics necessary for long-range missions.

Key Features

Versatility is a major highlight of the Mark4-7. The frame supports dual mounting patterns—30.5×30.5mm and 20×20mm—allowing you to fit a wide variety of flight controllers, 4-in-1 ESC stacks, and VTX units. The center and rear stack locations provide flexibility for weight distribution. Additionally, the 25mm standoff height creates a spacious “bus” for wiring and accessory mounting.

The frame includes quick-maintenance features such as easy-swap arms, allowing you to replace a damaged component without disassembling the entire stack. For camera protection, the kit includes 2.5mm carbon side plates that house standard 19mm micro-sized FPV cameras. The high-grade YFS 12.9-grade screws ensure that every component stays securely fastened even under high vibration.

Applications

The GEPRC Mark4-7 is the “go-to” chassis for Long-Range FPV Exploration, providing the efficiency needed for 10-minute+ flight times. In Cinematic Filming, it carries GoPros and other action cameras with minimal vibration. Freestyle pilots appreciate the 7-inch “grip” and power when using high-torque 2807 motors. It is also an excellent platform for Digital HD Builds (DJI O3, Walksnail), offering dedicated mounting space for Air Units. Furthermore, it is a reliable choice for Autonomous Waypoint missions. Finally, its robust nature makes it a favorite for Mountain Surfing where unpredictable winds require a stiff, responsive frame.
