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.
This manual is for multi-rotor
installation & operation.
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:

Attitude Stabilized Mode

Hovering Mode

Auto Return To Launch Mode(RTH)
GPS Module
GPS module– enables the FY-41AP to calculate the flight course & sense the
exact location of the aircraft. GPS Data enables the aircraft to utilize Auto Return To
Launch Mode (RTH) and Hovering Mode.
OSD System
FY-41AP has integrated OSD hardware with optimizing display interface.
Critical flight parameters are displayed like Altitude, Speed, Direction, flying voltage
and Amp draw.
Power Manager Module
FY-41AP can connect Power Manager Module which is integrated with Current
Sensor module and Voltage-Regulating module. Current Sensor is used to check
voltage, Amp draw. The integrated Voltage-Regulating module provides stable +12V
to FPV video camera and video transmitter.
Function Introduction
Altitude Stabilized Mode
41AP can auto stabilize the aircraft flight altitude in this mode. Keep the pitch
and roll stick in center position for 0 °altitude. The pitch and roll stick has an
endpoint of 45 ° and has linear control over the flight altitude, with a maximum
angular velocity of 150 ° / s. The yaw stick in the center position will lock on to the
current course. The yaw stick can linearly control the aircraft‘s rotation rate, with a
maximum rotation rate of 135 ° per second. The throttle stick directly controls the
aircraft‘s ability to climb and decline; the climbing and declining rate is directly
related to the throttle.
Hovering Mode
