FY-41AP FIRST FLIGHT TEST CHECKLIST
1)
Before your first flight, please reconfirm that the FY41AP have been
installed as recommended by this manual. Further ensure vibration is at
acceptable level (check Red LED).
2)
Check the FY-41AP installation (arrow) direction.
3)
Power up the system and confirm SW-1 & SW-2 switches are correctly set
via the LED flashing and colour.
4)
Switch the FY-41AP to Auto Stabilized Mode (ABM) and confirm the
automated control surfaces direction is correct. Make sure GAIN is not set
too high (will result in oscillation).
5)
Confirm the gyro is working properly: place plane
stationary
and SW-2
is in Deactivated Mode (Null). Proceed with flight test if there is no purple
LED flashing.
6)
After completing the above basic check, you can take off in either manual
mode or ABM.
7)
If required, adjust your transmitter trims
until the plane fly level.
8)
Add plane roll & pitch input and observe the rate of automatic balance
action. If recovery to level flight is too quick (flight control feels sluggish)
then gain may be too high. Land and adjust Gain according to the channel
involved (AIL, ELE or RUDD).
9)
If the aircraft shows rapid oscillation during ABM, this means Gain is
extremely high. Quickly land the plane and reduce gain accordingly.
10)
If recovery to level flight is too slow, that means Gain is too low. Land and
increase gain accordingly.
11)
To test the RTL function, fly in ABM at cruising speed to a comfortable
distance. Switch (SW-2) to RTL Mode. The plane should turn & fly towards
home. Upon reaching home point, it will automatically circle above. If the
test is successful, you may switch back to ABM and fly further out to test
the RTL again.
