GALYCHYNA F405 V2 6S/60A Quadcopter Flight Stack

Introducing the GALYCHYNA F405 V2 6S/60A flight stack from the 603700 FPV brand — a comprehensive solution for building 7"-10" FPV drones. The kit includes the «Galychyna v2» flight controller and the «Frankivsk v2» electronic speed controller (ESC), which ensure high reliability, extended connectivity options, and minimal preparation time for the first flight.

Purpose and Compatibility:
The stack is optimized for popular 10" designs and is suitable for 7"-10" frame sizes, providing a nearly ready-to-fly solution. It's an ideal choice for engineers and enthusiasts planning to build heavy-lift or cargo multicopters, including hexacopters, by increasing payload capacity with the addition of two extra ESCs for the arms.

Power and BEC:
The flight controller is equipped with two independent BECs: a fixed 5V 3A and a switchable 5V/9V/12V 3A (voltage selection is done by soldering a jumper on the board). The second BEC can power additional modules or a re-targeting board in «kamikaze» configurations.

Extended Interfaces and Outputs:
The controller features 6 UART ports for connecting a receiver, GPS, telemetry, and other modules. Three servo outputs (S1, S2, S3) are provided — one located near the camera for controlling a pan/tilt mechanism, and the other two for initiators or servos. Two controlled PINIO outputs with 5V/1A switching are available for powering external devices. The flight controller supports 6 outputs for ESCs (M1–M6), allowing for hexacopter assembly without complex modifications.

Pre-configured Settings and OSD Functions:
The controller comes pre-configured for the most common 10" setup, reducing preparation time. It offers the ability to switch video channels during flight to avoid cross-interference and ensure stable video transmission. The hidden home point function (OSD) partially overlays the image, without revealing the coordinates of the starting position, which reduces the risk of detecting the launch site if the signal is intercepted.

Firmware and ESC Operation:
The «Frankivsk v2» electronic speed controller runs on Bluejay firmware with Bi-directional DShot support and RPM filtering for smooth and precise motor control. Custom startup melodies are available. The ESC supports DSHOT300/600 protocols and has a built-in current sensor up to 132 A.
