5.15.2 Calibrating the Compass
Compass calibration should be done with the model away from
electrical fields and metal objects. The best place to calibrate the
compass is outdoors, at the field where you will be flying.
5.15.2.1 Steps before Calibrating
Before calibrating the compass, make sure that the compass is
installed correctly, and that all equipment you plan to fly with,
including cameras, canopies, etc., are fully installed on the model,
and turned on. Adding equipment later can impact the compass
calibration!
5.15.2.2 Calibrating using the Stick Menus
To calibrate the compass using the stick menus, follow these steps:
1) Invoke Compass Calibration mode by selecting the “Compass Working ok (if used)?” menu item under
the “Preflight Checklist” menu.
2) When your model is away from metal
objects, click the mode switch once to
start the process, which will cause the
OSD menu shown above to appear.
Vector LED should now be
solid GREEN .
Then, move your radio away from your
model.
3) Slowly tumble (pitch, roll and yaw) the
model in all directions, until the
Calibration Progress reaches 100%, and
the Vector LED turns
solid RED .
Tumble method doesn’t matter, but
make sure model goes inverted during
tumble.
Note: for large fixed wing models
where the above calibration method
is awkward, an alternate tumble
method is to pitch and roll the model
as much as possible, while slowly
spinning (pirouetting) your body.
4) Hold the model horizontally level in front of you, with the GPS arrow pointing directly toward your
body.
5) Slowly spin (pirouette) your body around 360 degrees (full circle) while standing in approximately the
same place., until the Calibration Progress reaches 100%, and Vector’s RED LED flashes . This spin
should take about 10 seconds.
6) The Vector will analyze calibration for 5 to 10 seconds. Rarely, if calibration is inadequate, tumble
calibration mode will start again, and the LED will turn solid GREEN again. Repeat steps 3-5 if this
occurs.
7) After calibration completes, verify proper compass operation as described in the “Testing the Compass”
section below.
