FY-41AP AutoPilot & OSD System Introduction
FY-41AP Module
FY-41AP is an inertial attitude measurement instrument used for FPV
flight on fixed-wing aircrafts and multi-rotors aircrafts. It has an integrated OSD
video overlay system that presents critical flight information such as power
management, airspeed, altitude, and flight direction via its electronic compass,
allowing for a clear visual flight while ensuring key information is within sight.
The new FY-41AP with its enhanced Altitude Control and GPS module,
can now realize improved pinpoint inertial navigation and automatic piloting.
Flight stabilization is achieved via an integrated 3 axis gyro, 3 axis
accelerometer, 3 axis magnetometer and a barometric pressure sensor. This
enables the module to accurately measure flight attitude, earth azimuth &
relative altitude to achieve:
 Extremely stable conventional flight pattern
 Stabilized 3D flight
 Automatically return to home (RTL)
 Fixed altitude flight
 Heading lock flight
 GPS waypoint flight
 Auto circling over a fixed GPS location.
GPS Module
GPS module– enables the FY-41AP to calculate the flight course & sense
the exact location of the aircraft. GPS Data allows aircraft return to home (RTL),
Auto Circle, Fixed altitude, Heading lock flight and fully autonomous flight via
GPS waypoints setting.
Airspeed Module
The Airspeed Sensor included enables the system to automatically control
airspeed via throttle management and prevents the aircraft from stalling and
ensures a stabilized flight.
Compared to GPS the Airspeed Sensor reacts quicker and is affected less
by the wind.
