ESP-FLUTTER robot butterfly flies on two servo-driven flapping wings

ESP-FLUTTER is a remote-controlled robot butterfly built by the maker Max Imagination. It weighs about 70 grams with its battery and flies by flapping its wings instead of spinning propellers. Each wing has its own fast digital servo, and a Seeed Studio XIAO ESP32-C3 board runs the servos, the battery monitor and LEDs along the wing edges.

You fly it from a phone browser over its own Wi-Fi, or with a regular RC transmitter through an optional ExpressLRS receiver. The wings are thin plastic film stretched over carbon-fiber rods.

By the creator's figures, a battery lasts about five minutes and the longest continuous flight so far is 1 minute 9 seconds. The firmware is free for personal use, while the 3D-printed frame files are a paid download. The creator says it is meant for makers who already have electronics and RC experience.
