SPARROW
3-
OSD
*
If you use custom mode, in order to simplify the operation, set the mode channel in the RC to
output an arbitrary value, and then observe which mode the FC switches to after losing control,
and then change the mode to RTH in the OSD.
For example, after the RC is failsafe, the flight
mode is automatically
switched
to A, then just set the position of A to RTH in the OSD.
➢
LEVEL CALI
Before calibration, place the FC horizontally and keep it still; if it has not been calibrated
for a long time or the installation direction has been changed, needs to be re-calibrated.
➢
Armed
NO GPS:
after the FC is initialized, it will be automatically armed, and the motor can be started
in all modes at this time.
With GPS:
after GPS fixed, except for RTH, the motor can be started at will, but before fixed,
only MAN can start the motor.
➢
Calibrate ESC
Step1
：
Switch to manual mode, push throttle channel to the max;
Step2
：
Power on(longer waiting time than directly connected receiver).
Step3
：
After ESC Beep, push throttle channel to zero.
FAQ
Q.Is the automatic action of the servos normal in RTH?
A.Yes. This is normal for RTH.
Q. Is there any output from the throttle channel when switching to RTH during flight?
A. It is recommended to switch to RTH after flying for more than 6 seconds. At this time, the
throttle is automatically controlled by the FC.
Q.Why does the motor keep beeping?
Q.RTH or FENCE mode becomes ALT.
A.RTH
and FENCE can only be used when the GPS is fixed, otherwise it will become the ALT.
Q.
Does the FC support telemetry of devices such as FM30 and HM30?
A.
Yes. The FC can output the MAVLINK protocol with two baud rates of 57600 and 115200.
