DoS in navigation mode is participate in throttle control, throttle control quantity will stack in the output of RC
throttle stick , as far as possible to control the plane in accordance with the cruising speed flight, cruising speed should
be set as the plane normal flat fly speed value, the unit is km per hour and the default cruising speed of DoS is 61 km/h.
“Cruising Speed Setting” settings window :
22. DoS flight test
1) According to the manual properly connected each module, pay attention to DoS module Vibration damping
installation.
2) Check the DoS installation direction.
3) Connect the power, check SW1 switch, and SW2 switch, through the indicator light check each mode can normally
switch or not.
4) Switch DoS to " Stabilized Mode ", reference manual 14 point. Check the control surface movements is correct or
not, if is not correct, you must not take off, it is necessary to adjust it to be right. At the same time observe the
quantity of automatic control output and estimate is appropriate or not, the first test flight, unfavorable to use too
much sensitivity.So you should after the flight look at the situation to adjust gradually.
5) The plane placed in the stationary state (can not be observed any rock), SW2 in Deactivated Mode (Null) to see if
there is purple light flashing, if there is,then need to gyro initialization (reference manual 15 point).
6) Check the influence of vibration on DoS (reference manual 11 point)
7) After completion the check, you can take off now, manual adjust the plane then switch to Stabilized Mode, observe
the flight state (also you can directly in the Stabilized Mode to take off).
8) Through the RC stick to trim the plane to level fly. Manually to change the plane roll and pitch, etc., to observe
the plane automatic balance situation. If recover to balance is too quick, don't feel flexible operation you can reduce
corresponding channel control gain (adjust
control gain,you need t o land the aircraft, and use DoS setting software
to adjust); If the pitch, roll and orientation rapid shaking, or flight speed increases appear sloshing,you need reduce
corresponding control channel gain; If recover to balance is too slow, the poor control ability is require you to
increase control gain.
9) Sensitivity gain adjustment need multiple flights to test, all kinds of aircraft flight characteristics is different, so the
use of control gain can also be different
10) After test well the stabilized mode, please keep the throttle at the cruising position
，then switch the SW2 to Return
To Launch Mode (RTL), then the plane should return to the home point, and circle after it reach the home point. If
this test successfully, then you can switch to the stabilized mode fly the plane to a farther distance to test the RTL
again.
