The Mark4 13" v2 Carbon Fiber Frame is a lightweight structural platform with a 539 mm wheelbase engineered for constructing heavy-payload quadcopters. Designed in an H-type layout using rigid 3K carbon fiber, it guarantees high torsional stiffness and minimal frame flex during loaded flight operations.

The airframe geometry supports 13-inch propellers and high-torque brushless motors paired with high-current electronic power stacks. An optimized mounting layout simplifies the integration of electronic modules, flight controllers, and cameras.

🫡 We Are a Team of Veterans

We evaluate the Mark4 13" v2 Carbon Fiber Frame as a proven, dependable foundation for heavy-duty unmanned aircraft builds. Reinforced 8 mm thick arms withstand rigorous flight loads and hard landings, while the 370 g structural weight preserves valuable payload capacity for high-capacity battery packs and specialized gear.

Standardized electronic mounting dimensions facilitate assembly, repair, and field maintenance. The second-generation design updates refine overall mass distribution and flight stability under heavy dynamic loads.

Commentary / Comments

The principal advantage of the Mark4 13" v2 Carbon Fiber Frame lies in its balanced stiffness-to-weight ratio. Utilizing 8 mm carbon arms, the structure dampens resonance from high-output propulsion systems, enhancing gyro accuracy and overall heading hold stability.

Dual mounting compatibility for 20×20 mm and 30.5×30.5 mm stacks offers versatility when selecting power management and RF hardware. Generous internal clearance accommodates high-power video transmitters, control receivers, and main power wiring without risk of abrasion against frame edges.
