Mark4 V2 7 inch 295mm FPV Drone Frame Carbon Fiber Freestyle
As a professional carbon fiber manufacturing and processing specialist, CFmade.com focuses on high-precision CNC cutting services. We specialize in providing custom cutting for the Mark4 series (including the classic Mark4 and upgraded Mark4 V2) 7-inch FPV drone frames. We not only supply standard full frame kits but also offer personalized processing based on your design files, ensuring every product meets aerospace-grade quality standards. Whether you’re looking for bulk purchases or single-piece customization, we deliver complete solutions using pure 3K carbon fiber sheets to help you quickly build high-performance freestyle or racing drones.
The Mark4 7-inch 295mm carbon fiber frame is a timeless classic in the FPV freestyle and racing community. Featuring an H-type (or True-X variant in some versions) structure, it strikes the perfect balance between lightweight design and exceptional strength. With a 295mm motor-to-motor diagonal, it’s optimized for 7-inch propellers, delivering outstanding agility, stability, and efficiency. This makes it ideal for mid-range flights, aggressive freestyle maneuvers, high-speed racing, and even cinematic aerial photography. The frame weighs only approximately 140g (depending on the specific version), allowing your quadcopter to be more responsive, achieve longer flight times, and handle demanding conditions with ease.

- ESC: 40A-60A 4-in-1 (BLHeli_32 or DShot protocol support)
- Propellers: 7-inch tri-blade (e.g., HQProp or Gemfan 7x4x3)
- Battery: 4S 1800mAh to 6S 2200mAh-3300mAh LiPo (depending on power requirements)
- VTX & Camera: 19mm camera compatible; recommended Caddx, RunCam, or digital systems like DJI
This combination delivers explosive thrust, extended flight times, and buttery-smooth control—perfect for both freestyle creativity and racing precision.
FAQ (Frequently Asked Questions)
Q: Is this the classic Mark4 or Mark4 V2? What’s the difference? A: We support both the original Mark4 (H-type with 5mm arms) and the upgraded Mark4 V2 (optional True-X layout, thicker arms up to 6mm, increased internal space). The V2 offers better strength and compatibility for heavy-duty or HD digital builds. Specify your preferred version when ordering.
Q: Does the kit include 3D-printed parts (e.g., camera mounts, antenna holders)? A: Standard kits consist of pure carbon fiber cut plates (bottom, top, arms, sides, etc.). We can bundle TPU 3D-printed accessories or recommend partners. Contact us for customized bundles.
Q: Why does the weight vary (around 121g-185g in some listings)? A: Variations depend on arm thickness (5mm standard vs. 6mm reinforced) and inclusion of protective plates or standoffs. Our standard version prioritizes lightweight at ~140g; opt for thicker arms for ultimate durability.
Q: What cameras and VTX systems are supported? A: 19-19.3mm camera spacing fits most micro FPV cameras. FC/VTX holes support both 20x20mm and 30.5×30.5mm stacks for seamless integration with mainstream electronics.
Q: Is assembly beginner-friendly? A: Yes—holes align precisely for straightforward building. Suitable for those with basic FPV experience. Beginners can follow Betaflight/iNav tutorials. We provide assembly guide PDFs upon request.
Q: What about warranty and quality issues? A: Every product undergoes rigorous pre-shipment inspection. We offer 7-day unconditional returns/replacements for cutting defects and free reships for transit damage (provide photos).
Q: Can I get custom modifications? A: Absolutely! As a direct manufacturer, we excel at alterations like custom hole patterns, thicker plates, or entirely new designs.

I’ve been flying FPV for a couple of years now, and the Mark4 V2 7-inch frame from CFmade.com has completely transformed my freestyle and mid-range builds. The precision CNC-cut 3K carbon fiber feels premium right out of the box—edges are perfectly chamfered, no burrs or carbon dust, and everything aligns flawlessly during assembly. At just around 140g, it’s incredibly lightweight yet ridiculously tough; I’ve survived multiple hard crashes into trees and concrete without a single broken arm, thanks to those thick 5-6mm arms and reinforced structure.
What really stands out is how balanced and responsive it flies. The True-X layout and lower center of gravity make flips, rolls, and power loops feel buttery smooth and predictable, with minimal vibrations even on 6S power. There’s plenty of room inside for my DJI O3 setup, big batteries, and extras like GPS—wiring was a breeze compared to tighter frames I’ve used before. Flight times are excellent, and the agility is addictive for freestyle sessions while still being stable enough for cruising mountains or bando diving.
CFmade.com’s custom cutting service is a game-changer too; the quality is aerospace-level, and it’s clear they know FPV inside out. If you’re building a 7″ quad, this frame is an absolute no-brainer—durable, performant, and worth every penny. Highly recommend!
