Product Features

Stable DC Structure: Drone arm DC design reduces shaking, enhancing flight stability for freestyle manuevers and long-range FPV—outperforming traditional frame structures.

Broad Compatibility: Fits DJI-O3/VISTA/RAD MINI 1W VTX, mainstream FCs, 3.6-inch props, and GoPro—eliminating need for adapter parts (saves cost for carbon fiber drone kit builds).

Durable Hybrid Build: Carbon Fiber Plates (shock-resistant) + 7075 aluminum alloy (anti-bend) protect FPV camera and internal electronics from crashes.

DIY-Friendly: Supports side panel decals (included red/multicolor stickers) for personalization; 3D-printed parts (GoPro mount, antenna fix) simplify custom setups.

Safety & Clarity: M-10 GPS compatibility ensures flight safety; hidden blades reduce visual interference, presenting pure FPV footage.

How to Assemble the Frame

Unpack & Verify: Check included parts (carbon fiber plates, aluminum components, screws, 3D-printed mounts) against the manual.

Mount Arms & Plates: Attach 4.0mm front/back drone arms to 2.5mm base plate using M2 screws; add mid plates for structural support.

Install Aluminum Components: Fix front/middle/tail aluminum parts to reinforce the frame, ensuring alignment with motor mounting holes.

Add Electronics Mounts: Use 3D-printed parts to install FC (match 20.5×20.5mm/25.5×25.5mm holes) and VTX (36×36mm/28×28mm holes); attach FC damping balls.

Finalize & Test: Mount camera (19-20mm) and GoPro (via 3D-printed base); apply side stickers; test fit motors/propellers before flight.

Application Scenarios

FPV Freestyle: DC structure handles high-speed turns and stunts; stable flight reduces footage shake for content creation.

Long-Range FPV: Compatible with DJI-O3/VISTA for clear long-distance transmission; M-10 GPS ensures safe navigation.

DIY FPV Kits: Ideal for building custom carbon fiber FPV drones—broad compatibility and included parts simplify assembly for hobbyists.

FPV Training: Durable build withstands beginner crashes; stable flight helps new pilots master maneuvers.

Value to Buyers

Cost Savings: All-in-one kit (no extra adapters needed); durable build reduces replacement costs for crash-prone FPV use.

Time Efficiency: Pre-matched mounting holes and included hardware cut assembly time by 30% vs. generic frames.

Performance Boost: DC structure improves flight stability; hidden blades enhance footage quality—critical for FPV content creators and racers.

Certifications and Compliance

Complies with CE and FCC standards, meeting global FPV drone frame regulations for safe commercial and hobbyist use.

Customization Options

Offers custom side panel colors (beyond standard black) and 3D-printed part tweaks (e.g., custom camera mounts) for bulk orders. Supports pre-cut carbon fiber plates via Carbon Fiber Cnc Cutting for specific user needs.

Production Process

Frames undergo:

 1) Carbon fiber plate cutting (precision CNC) and aluminum alloy machining; 

2) Surface treatment (anti-corrosion for aluminum, smooth finish for carbon fiber); 

3) Kit assembly (parts verification, hardware matching); 

4) Quality testing (structural stability, hole alignment).

FAQ

Q: Is it compatible with 5 Inch FPV Drone Kit components?

A: No—it’s a 3.6-inch frame, optimized for 3.6-inch props; use with 3.6-inch-specific FPV components for best performance.

Q: Can it fit naked GoPro cameras?

A: Yes—included 3D-printed bases support both full-size and naked GoPro models.

Q: Does the frame come with a GPS module?

A: It’s compatible with M-10 GPS (not included); the frame has mounts for easy GPS installation.

Q: Is the carbon fiber plate replaceable if damaged?

A: Yes—replacement carbon fiber plates are available as drone accessories; matching holes ensure easy swap.

Q: What’s the weight advantage for FPV flight?

A: 110g lightweight design reduces drone overall weight, improving maneuverability for freestyle and extending battery life for long-range flights.
