Product overview
The Holy Stone HS420 brings indoor flight practice and simple camera functions together in a compact drone with full propeller guards. Intended for children aged 8+ and first-time pilots, it supports one-key takeoff and landing, altitude hold, headless mode and speed switching. Circle Fly, High-Speed Rotation and 360° flips add further flight options. After pairing and calibration, Throw to Go allows launch with a gentle upward toss. The HS420 has no GPS positioning or GPS Return-to-Home.
The built-in Wi-Fi camera captures 1920 × 1080P photos and video at 20fps. Its angle adjusts manually from -90° to 0° before takeoff. With a phone connected to the drone’s Wi-Fi, the HolyStone-FPV app provides live viewing, gesture photo/video and Trajectory Flight. Supplied equipment includes the drone and transmitter, two USB charging cables, four extra propellers, a screwdriver, a propeller spanner and instructions. Accessory quantities and colors can vary by product version or purchase channel; the transmitter’s three 1.5V AAA batteries are not included.
