will need reduce the level of vibration on your aircraft, add additional dampening support or change the
installation location.
Too much vibration may cause abnormal condition
1. In the stabilized mode, the plane can‘t keep steady, may roll or pitch
or other abnormal conditions.
2.Unde r the stabilized mode, after flying a while, it will deviate the steady position, can‘t keep steady flying.
3. All the navigation modes with GPS can‘t work normally.
12. Switch channel setting
DOS needs two 3 way-switches to control flying: SW1 is used to set manual
mode, stabilized mode,and 3D mode. SW2 is used to set Auto Return To Launch
Mode mode, Fixed altitude and Heading lock flight Mode and Auto Circling Mode,
which can be set by DOS setting software.SW2 had priority to SW1,only when
SW2 switch to cancel(Null) positon ,the SW1 can work.
After setting, operator can ensure if it is correct by judging the color and
flashing situation of the indicator lights.
