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.

FAQ

Q: What propeller and motor sizes does the Lark X7 support?
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.

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 variants?
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 for routing a digital camera-to-VTX connection through the frame.

Note: Package contents cover the frame kit and its assembly hardware only. Electronics and accessories shown in build photos are for illustration and are not included.
