may result in damage of your aircraft due to excessive throttling.
You can observe the "GPS velocity" on GCS software when in flight, and to evaluate
the aircraft's cruising speed.
Circle radius: It means the radius of the hovering flight. Speed of the plane which
achieve 60 km/h, the circle radius should be set to more than 80 meters .We suggest that
the circle radius should be set more than 1.6 times of the flight speed. Such as the speed
of the plane is 100 km/h, the circle radius suggest that set in 160 meters. If the circle
radius is set too small, hovering flight may not be able to normal, maybe the plane will
decrease flight altitude, even cause the dangerous of air crash.
Method one: Setting FY-41AP Lite via remote control and OSD overlay
menu
You can set the” Target speed” and the “Circle radius” via the “Flight” option in the
OSD menu (Speed: Target speed, CIR RAD: Circle radiu).
Method two: Setting FY-41AP Lite via “FYGCS 5.11 for 41&DOS” software
Step Six: Gyro and airspeed sensor initialization
Gyro Initialization: When doing the gyro reset, please keep the aircraft static. It’s
better to do the gyro reset before each flight.
