Kids OK, with an adult
DIY project. Children must build this only with an adult (16+ years) beside them at all times. Not suitable for children under 8 years.
An adult charges and handles the LiPo battery, with a proper LiPo charger. Fly indoors in an open room, away from faces, hair and pets, and keep fingers clear of the propellers.
Strictly follow the description given with this video.

How it works
- The PCB frame carries the ESP32, the motion sensor and four MOSFETs, one for each coreless motor.
- The ESP32 makes its own Wi-Fi; the phone page sends throttle and direction.
- The motion sensor reports tilt 250 times a second, and the ESP32 speeds up or slows each motor to stay level.
- A battery-sense pin watches the 1S LiPo and lands the drone when it runs low.
