iFlight BLITZ Mini F7 V1.1

iFlight BLITZ Mini F7 V1.1

The iFlight Blitz is a mini 20x20 flight controller with an improved circuit design, better components, and lower electrical noise. The flight controller has many plug-and-play ports including DJI HD VTX Connector, GPS, Crossfire, and more. The flight controller has LED indicators for visual debugging. Paired with a 55A Blitz ESC makes this a power stack in a small package.
