The Skyline32 Acro flight controller with its Cleanflight and Baseflight (NAZE32 firmware) support brings to you the innovation only available from the ever-growing Open Source community.

This compact  flight controller is perfect for all multi-rotors whatever their size, but is particularly suited to smaller models where space is limited and performance important.
Unique wire-to-board connectors make wiring quick and simple, while the micro USB port allows you to customise your setup and fine tune the Skyline32 Acro from your PC.

A total of 6 flight modes are available, including Altitude hold and the beginner-friendly Head-free (aka Headless) mode which maintains stick orientation relative to the pilot regardless of the direction of flight.

For peace of mind, a low voltage detection circuit is included along with a warning buzzer.
The Skyline32 Acro supports OSC and OLED functions and is compatible with Spektrum satellite receivers for added versatility.
