FY-91Q Multi-rotor System
Basics on how the system works:

Inertial Stabilizer: The FY-91Q utilizes an attitude flight stabilization system
(AFSS) which is inertial sensing based. The system also incorporates an
autonomous flight control system.

The FY-91Q AFSS integrates a three-axis gyroscope combined with tri-axial
accelerometers to sense and create a drift-free 3 dimensional stabilization
system.

The FY-91Q also utilizes GPS and barometric pressure sensing to obtain
accurate aircraft positioning and altitude.

By combining sensor data from the gyros and accelerometers, together with
altitude and GPS positioning, an accurate inertial navigation and autopilot
system is formed. Fixed positioned and altitude hover and return to home is just
a switch away.

This product is still under intense Research and Development. FeiYu Tech has
enabled firmware upgrading via a USB-TTL Connector. As new algorithms are
developed for the autopilot system, you can download the upgraded firmware
from FY website.
Barometer and GPS & COMPASS module:
FY-91Q control module incorporates an accurate barometric pressure sensor. At start
up, the take-off air pressure is measured, providing the autopilot with an accurate
relative height data.
 The GPS & COMPASS module provided with the FY-91Q Navigation
Edition consist of a three-axis magnetic sensor and high sensitivity GPS
receiver. This module enables the autopilot to sense the flight course and
exact location of the aircraft.
 Note that if the FY-91Q is not connected GPS & COMPASS module, it will
function as purely as a flight stabilizer for multi rotor aircraft. The
autonomous flight system cannot be engaged.
 For the autopilot to function, the GPS Receiver must detect at least 5 satellites.
