About RC transmitter
：
The RC transmitter must be set to fixed-wing mode and do not set any
mix-control. Any channel can’t be inverted on FUTABA RC transmitter, but all of
the channels on Jr and WFLY RC transmitters need to be inverted.
For the RC transmitters of other branch, after channel calibration, check
whether the actual servo operation is the same as “Manual servo position”
showing on GCS , orientation/aileron/elevator display as left/right and push/pull,
hands off RC transmitter control displys as Neutral position, the max servo
position is 40, example: the max left servo displays as left40; the mini throttle
displays as 7 and the max as 90. It's correct if the actual servo operation is the
same as “Manual servo position” showing on GCS and if not same need to reset
channel to be reverse on transmitter.
4 Magnetic Course Calibration
There is no need to calibrate the magnetic course in manual mode, and
the
“Course angle”
in data page of GCS will keep displaying as 0
. But
in GPS mode
,
the magnetic course calibration must be finished before take-off
. Ferromagnetic
substances placed on multi-rotor or around its working environment will affect
the reading of earth magnetic for digital compass, it also reduces the accuracy
of the multi-rotor control, or even reads incorrect heading. Calibration will
eliminate such influences, and ensure MC system performs well in a non-ideal
magnetic environment.
The magnetic data will display once after calibration and
be saved to the autopilot.
