RJX SP Racing F3 Flight Controller for FPV RC Drone Quadcopter;

Specification:

Acro Version: Standard model for racing/ acro flying

Description ：
1.The hardware was designed by the lead developer of Cleanflight to be more capable than the previous-generation STM32F1-based boards after hearing feedback from the Cleanflight users, contributors and top-pilots.
2.SP Racing F3 Flight Controller Acro 6 DOF for RC Multicopter for DIY Mini 180 190 195 210 220 250 280 300 330 RC Drone.
3.Supports OneShot ESC and more than 8 RC channels. Supports more flight controllers, including CC3D, CJMCU and Sparky.
4.Many more features such as RGB LED strip support, Autotune, In-flight PID tuning with your radio, blackbox flight data logging etc.
5.Better coding practices and introducing tests, easier to maintain and for future development. (Dominic has software development background). Additional PID controllers that uses floating point arithmetic operations. (now has 3 built-in PID Controllers)

Features:
No-Compromise I/O
Use all the features all the time; e.g. Connect your OSD + SmartPort + SBus + GPS + LED Strip + Battery Monitoring + Sonar + 8 motors - all at the same time.

Configurable
The SPRacingF3 runs Cleanflight which can be configured to suit your needs using a cross-platform GUI (Windows/OSX/Linux).
