Attention:
Vibration LED takes precedence over GPS positioning LED,you must make sure that
the gyro is not need to initialize (Red light continuous flashing), only in that you will
know the GPS positioning success or not.
7. Vibration damping installation:
Damping installation : Good damping installation is the basis of DoS can do normal work,
also can decide whether DoS to maximize play flight performance or not, and make sure
you have a great flight. Otherwise may cause serious flight accidents, for example: flight
jitter, flight attitude gradually deviation and tilt from the balance position, and Hovering
mode unable to keep the flight altitude and position. You can use your own DIY shock
absorbing devices to do the shock absorbing, but we recommend using suspending
damping installation, especially use DoS vibration absorbing mount which product by
FeiYu Tech,it can meet the requirements of most of the conditions, and in addition you
need to try to reduce the vibration of the motors and oars
.
Installtion position:Each modules install to a suitable position is conducive to further
enhance the performance of Hovering mode. DoS module installation position should be
as far as possible to close to the center of the aircraft, the aim is to reduce the disturbance
to the internal IMU position sensoring when the aircraft tilt or rotate. In addition also you
have to consider a very important factor, that is as far as possible to reduce the interference
to the DoS internal magnetic sensor which caused by installation position. There will be
caused interference to magnetic sensor,such as surroundings have strong current, motor
rotation, battery, etc. We need to do is to give full consideration of these two factors,
compromise to select a suitable position for install it. GPS module should be placed as far
as possible to the center position,that can reduce the interference to GPS data when it level
rotating. Also you can put the GPS module to a high place use a stent, the practice shows
that can effectively reduce the interference to GPS signals which caused by other devices,
