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
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.
