(5) When the mechanical structure of the aircraft is changed.
(6) If the flight direction appears to be shifting (meaning the aircraft doesn’t “fly
straight”).
Calibration procedure:
Please power on, and level holding the frame to do the rotate clockwise (or
counterclockwise) 8-10 circles (rotational speed less than 60 degrees per second),
after
complete the calibration, On SW1,switch stabilized mode to hovering mode 6 times, time
interval has to be less than 3 seconds,use the “Gyroscope Reset” procedure to save the
compass calibration parameters.
Pre-flight test:
The following steps is very important, please make sure to check them
each time before take off, otherwise you may not have a normal flight.
1.
Check the installation of the equipments and damping devices is normal or not, check
the motors and oars are solid and reliable install or not.
2.
Power on, do not to do the combination Stick Commands (CSC) in stabilized mode to
start the motors yet, observe the DoS indicator first, if the red LED continues to flash,
that means the gyroscope needs to initialization, you must to initialize the gyroscope
(Please refer to the “Gyroscope Reset”).
3.
Observe the DoS indicator if there is a green light flash, that means the GPS has been
positioning success and have record the home point, satisfies the requirement of flight,
but after that you can wait over 30 seconds to let the GPS positioning is more stable
and accurate.

Other considerations
(1)
Please as far as possible to maintain the current altitude when switch Attitude
Stabilized Mode to Hovering Mode. In Hovering Mode, DoS can automatic control flight
altitude.Climbing and descending rate is directly related to the throttle, when the throttle
stick is in the center position,DOS automatic locks the altitude, in maximum means climb
rate is 3 m/s, in minimum means decline rate is 1.5 m/s.Throttle stick can linear control the
aircraft climb and decline rate.
There are two very important points:
1) To prevent the altitude sudden change caused by the throttle, you have to put throttle
stick back to balance flight position, when switch off hovering mode.
2)After connect the GPS module,please do not take off yet.You should wait the GPS
positioning LED shows the GPS positionning is in a good condition(Green light double
flash each loop or triple flash each loop).
(2)
1)When flight 0.8 meters above to the ground will have a good control effect, if you
descending to the ground in hovering mode may caused the aircraft altitude volatility.
2)You can not completely shut down the throttle in Hovering Mode or Auto Return to
Launch Mode, In order to ompletely shut down the throttle you need to switch to altitude
stabilized mode.
3)Without the GPS module,swith to Hovering Mode or Auto Return to Launch Mode will
automatic into Fixed Altitude Flight Mode.
(3)
In hover mode, you can change the aircraft position by RC sitcks, when release the RC
