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. MicroVector 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 MicroVector 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 MicroVector’s RED LED flashes. This spin should take about 10

seconds.

6) The MicroVector 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 section 6.17.3 - ‘Testing

the Compass' below.

6.17.2.3 Calibrating using the Mode Switch

For your convenience, you can calibrate the compass without using your video display, as follows:

 Toggle mode switch 7 times – the MicroVector’s LED should flash a fast RED/GREEN

 Follow steps 2-6 above.

 The LEDs should now return to normal, indicating that the compass calibration is complete

 After calibration completes, verify proper compass operation as described in section 6.17.3 - ‘Testing

the Compass' below.

6.17.3 Testing the Compass

6.17.3.1 Load Testing the Compass

If you are not sure that your compass is mounted far enough away from motor/ESC wiring, or other sources of

interference, you can test it by operating your model under load, while it is stationary. First, make sure the

compass is displayed, and note the compass reading. Then, if you can do so safely, run the model at full throttle

with propeller(s) attached, but with the model secured so that it cannot move. If the compass reading changes

significantly (more than a few degrees), that suggests the GPS/Mag is mounted too close to electrical wiring or

other sources of interference.
