1. FY-41AP Lite AutoPilot System Introduction
FY-41AP Lite Module
FY-41AP Lite is an inertial attitude measurement instrument used for FPV flight on
fixed-wing 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 Lite 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,
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

Auto circling over a fixed GPS location.
GPS Module
GPS module enables the FY-41AP Lite to calculate the flight course & sense the
exact location of the aircraft. GPS data allows aircraft return to home (RTL), auto circle,
and control straight line navigation.
Airspeed Module
The FY-41AP Lite can be connect to the airspeed sensor (When don ‘t connect the
airspeed sensor, the FY-41AP Lite also can work normally).The airspeed sensor can
measure the airspeed of the aircraft. Compared to the GPS speed the airspeed have the
characteristics which is small delay and small affected by the wind. This characteristics
can achieve the effective control of the throttle, improve the efficiency of flight and flight
safety
OSD System
FY-41AP Lite has integrated OSD hardware with optimizing display interface. Critical
flight parameters are displayed like altitude, speed, direction, flying voltage and amp draw,
and most display parameter outlay can be changed via RC control.
