The Skystars F411 and KO25 BLHeli_S stack provides a complete control and power solution in a highly compact footprint. Designed specifically for sub-250g micro quads, toothpicks, and high-performance whoop builds, this stack pairs an STM32F411 flight controller with a 25A 4-in-1 ESC. The FC features a clean layout with easily accessible solder pads to simplify wiring in tight canopies, while the BLHeli_S ESC ensures smooth commutation for small, high-KV motors.

Key features

Compact 20x20mm mounting layout designed specifically for tight micro and toothpick frames
25A continuous output with a 35A burst rating to handle aggressive throttle punches
Built-in 5V/2A BEC to reliably power your receiver, camera, and video transmitter
Native BLHeli_S ESC firmware with full compatibility for Bluejay flashes
