DolphinRC Lark X7 7-Inch FPV Drone Cinematic Frame Kit

The DolphinRC Lark X7 is a 7-inch deadcat-style (DC) FPV frame kit built for long-range cruising and high-definition cinematic flying. A 322mm wheelbase carbon fiber chassis with aerospace-grade aluminum alloy hardware keeps the airframe rigid yet light at just 388g, leaving plenty of payload headroom for a GoPro-class action camera and a 6S long-range battery. From assembly and tuning to real-world flying, the Lark X7 is designed to make the whole process straightforward for both seasoned builders and pilots stepping up to their first 7-inch rig. Choose your option from the dropdown menu above: the standard Frame Kit, or the Frame Kit + 250mm Coaxial Cable bundle, which adds a 250mm straight-to-right-angle coaxial cable for clean digital camera-to-VTX wiring. Key Features ✅ Carbon Fiber + Aerospace Aluminum Structure — High-strength carbon plates paired with aluminum alloy standoffs and camera cage deliver a stiff, crash-resistant airframe that stays stable in high-speed flight and gusty conditions. ✅ Quick-Release 6mm Arms — Thick 6mm arms with a tool-friendly quick-release design let you swap a damaged arm in minutes instead of rebuilding the whole quad. ✅ Integrated Audio-Visual Alert System — Dual high-decibel buzzers help you locate a downed quad fast, while the built-in RGB Bluetooth lighting module is fully configurable through a smartphone app for different scenes and visibility needs. ✅ Adjustable HD Camera Mount with Full Alloy Protection — The 20mm camera mount offers adjustable tilt front and rear, wrapped in an all-around aluminum alloy cage that shields your HD camera in hard landings. ✅ Anti-Interference Antenna & GPS Mounting — A dual-mount layout for the receiver antenna and GPS physically isolates them from strong magnetic sources, improving positioning accuracy on long-range flights. ✅ Builder-Friendly Electronics Bay — Modular split side panels, an external parameter tuning port (adjust settings without opening the frame), and standard 30.5mm stack / 25.5mm + 30.5mm VTX mounting make it compatible with the vast majority of mainstream electronics.

A: It is designed for 7–7.5 inch propellers with 2806 or 2808 size motors (19mm / Ø3mm mounting pattern, 4 holes). Q: Does the frame kit include motors, a flight controller or a camera? A: No. The package contains the frame and its mounting hardware only — all electronics, propellers and battery are purchased separately, so you can choose the exact setup you prefer. Q: What battery should I use for long-range flights? A: DolphinRC recommends a 6S 3500mAh LiPo for general flying, or a 6000mAh Li-ion pack for maximum long-range endurance. Q: Can I adjust flight controller settings without opening the frame? A: Yes. The Lark X7 has an external parameter tuning port, so you can plug in and tune without disassembling the airframe. Q: What is the difference between the two options? A: The Frame Kit includes the frame and assembly hardware only. The Frame Kit + 250mm Coaxial Cable bundle adds one 250mm straight-to-right-angle coaxial cable — handy for routing a digital camera-to-VTX connection through the frame.
