Product Details
Thirteen-inch frames usually mean one thing: heavy industrial gear that weighs a ton and flies like a truck. The MARK4 V2 13 inch carbon fiber drone frame is different. At 370g it’s less than half the weight of comparable X-type 13-inch platforms — because the H-type layout runs arms straight through the center instead of fanning them out. Less carbon, less weight, same prop diameter. That’s the structural efficiency of H-type at this scale.
The 8mm arms are the thickest in the MARK4 V2 series. At 536mm wheelbase with 13-inch props spinning, 7mm arms would flex enough to show up in your footage and your altitude hold. We went 8mm because this frame crosses the line from pure FPV into commercial territory — and commercial operators don’t accept “a little wobble.” Each arm is cut from our own 3K T300 carbon fiber sheet, and the extra thickness doesn’t add unnecessary weight because we optimize the arm profile with lightening cutouts that preserve stiffness where it matters and remove material where it doesn’t.
The 536mm wheelbase opens up a frame class that most FPV brands skip entirely. It’s too big for freestyle and too light for the 10mm-arm crowd. But that’s exactly the space where a lot of real work happens — survey flights that need 13-inch efficiency but don’t want to carry an 800g frame, agricultural prototype rigs that need flight time more than payload, and research platforms where every gram saved on the frame is a gram available for instruments.
Side plates stay at 2.5mm — the same as the 10-inch version. At this wheelbase the side plates experience more leverage from arm-mounted motors, but the H-type structure transfers those forces along the arm axis rather than across the side plates, so 2.5mm is sufficient. If you need 3.0mm side plates for extreme rigidity, that’s what our V3 Pro 13-inch is for. This 13 inch carbon fiber drone frame is the lightweight option — V3 Pro is the heavy-duty one.

Package Includes
- Full set of 3K T300 carbon fiber plates (arms, bottom/middle/top plates, side plates, camera plates)
- Aluminum standoffs
- Stainless steel screws and hardware
- Arm soft mounts (vibration damping)
- Battery pads
- Battery straps
Applications
- Commercial survey and mapping — 13-inch props on 8mm arms deliver 25+ minute flights covering large areas. This large FPV frame is light enough to fly FPV but stable enough for photogrammetry
- Agricultural spray prototypes — Test spray rig configurations at scale without committing to an 800g industrial frame. 370g leaves more payload budget for tanks and pumps
- Long-distance delivery testing — 536mm wheelbase handles 6S-8S packs and payload modules. Validate your delivery concept before scaling to production hardware
- Research and scientific platforms — Every gram saved on the frame is a gram available for sensors, samplers, and communication equipment. H-type efficiency at 13-inch scale
Why Choose YTCarbon
- Sheet-to-frame, one factory. We press our own 3K T300 carbon fiber sheet from raw fiber, then CNC cut every arm and plate in the same facility. Full material traceability from raw material to finished 13 inch carbon fiber drone frame — no middleman, no guessing
- Batch consistency. CNC tolerances within ±0.05mm mean your tenth reorder fits exactly like your first. Chamfered internal corners, deburred edges, dimensional inspection on every part
- No MOQ, ever. One frame for a research project, a hundred for a product launch, a thousand for distribution. Same production line, same quality standard
- ISO 9001 certified. Independently audited quality management system. Material Test Reports and compliance documentation available for commercial certification requirements
- Try before you commit. Order a sample at cost. Fly it, load it, crash it. Make your volume decision based on real performance, not marketing claims
Certifications
Every frame we ship is backed by documented quality credentials. We hold ISO 9001 certification for our quality management system, and our carbon fiber materials carry RoHS and CE compliance — which matters if you’re reselling into the EU or supplying customers who need traceable documentation.

How We Manufacture Your Frame
A lot of frame sellers can’t tell you how their product gets made because they don’t make it — they buy it from a supplier who buys it from another supplier. We’re different. The process below shows what actually happens inside our facility: raw 3K T300 carbon fiber comes in, we lay it up and press it into sheet, then our CNC machines cut every plate and arm to spec. After machining, each part gets a visual and dimensional inspection before it goes into the package.
