Rush Blade Analog stack is a combination of a top control unit and regulator designed for freestyle and racing helicopters with analog video transmission. The control unit has components on one side only and is protected by a metal cover, which increases the protection of the board. Most other components can be connected to the board using connectors, but soldering pads are still available from the bottom. The control unit has an F7 processor, an IMU unit MPU6000, 5 UARTs and 16MB of memory for a blackbox. Powerful other components are provided by a strong 5V BEC.
