Please do the calibrate if the following circumstances occur:
(1)The first time you install DoS&41AP on your aircraft.
(2)When the aircraft mechanical setup is changed
(3) If the DoS&41AP module is re-positioned.
(4) If electronic devices are added/removed/ re-positioned (Main Controller, servos,
batteries, etc).
(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&41AP 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&41AP 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.
12. 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&41AP 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&41AP 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
