Product Details
692mm wheelbase. 555g. 15-inch props. This is the biggest frame in the MARK4 lineup, and it’s still lighter than the Ares 13-inch. That’s not a typo — the H-type layout at this scale is so carbon-efficient that you get 15-inch prop clearance and a payload bay bigger than some X-frames two prop sizes smaller. If you’ve been assuming that large frames have to be heavy, this one changes the math.
The V3 Pro 15 inch shares the same arm thickness and side plate spec as the V3 Pro 13 inch — 8mm arms, 3.0mm side plates, 3.0mm bottom and middle plates. The difference is the span. Going from 565mm to 692mm wheelbase means 15-inch props spin with comfortable clearance, and the center stack has room for serious electronics: flight controller, companion computer, dual GPS modules, long-range radio, and a battery that actually lasts. The H-type vertical stack keeps everything in a straight line — FC on the bottom, companion board in the middle, radio on top. No lateral spreading, no cable spaghetti, no wasted space.
Why would you pick this over the Ares 15-inch? Because not every 15-inch build needs to be a tank. The Ares 15-inch runs 10mm arms and a 4mm bottom plate in a Wide X layout — great for fixed industrial payloads where you bolt it together and never touch it again. But if you need to swap components between flights, adjust your stack for different missions, or just fit standard FPV parts without adapters, the H-type layout is simply more practical. The MARK4 V3 Pro 15 inch carbon fiber frame is built for operators who change configurations, not operators who set it and forget it.
At 555g, you’ve still got plenty of payload budget. A 6S 8000mAh Li-ion pack weighs about 450g. A typical long-range electronics suite adds another 150g. That puts you around 1.15kg AUW without payload — and 15-inch props on 4006 or 4010 motors will pull that with authority. You’re not building a racer. You’re building something that stays in the air for 40 minutes, carries real equipment, and comes back reliably.

- Aluminum standoffs
- Stainless steel screws and hardware
- Arm soft mounts (vibration damping)
- Battery pad
- Battery strap
Applications
- Ultra-long-range FPV — 15-inch props on a 555g frame means 35–45 minute cruise times with 6S Li-ion. This is the frame for crossing distances that smaller builds can’t reach
- Large equipment transport — 692mm wheelbase gives you payload bay space for delivery modules, relay stations, or inspection gear that won’t fit on 13-inch frames
- Long-distance pipeline and corridor inspection — H-type stack fits companion computers for autonomous waypoint missions. 15-inch prop efficiency means fewer battery swaps per kilometer of coverage
- Operators who prefer H-type over X-type — Vertical component stacking, front-to-back cable routing, easy arm swaps in the field. If you’ve been flying H-type and want to go bigger without switching layouts, this is it

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.
