Reviewers note the kit's inclusion of a Pixhawk 2.4.8 and integrated power distribution makes it comparable to higher-end DIY platforms, while the carbon-fiber frame and 30A ESCs provide a solid foundation for payload-heavy or autonomous applications.
Users appreciate the high component quality and value, but report frustration with missing instructions, short motor screws and occasional missing frame pieces.
Professional reviewers highlight its lightweight build, reliable 2.4 GHz control, bright goggles and useful Bluetooth simulator integration, while noting the trade-offs of analog video and brushed motors.
Everyday users love the ease of use, durability and immersive goggles, but frequently mention the short flight time and the need to buy extra batteries.

“Perfect for my 10-year-old-easy to fly and very durable.”
