16.8 If compass calibration fails
D Compass calibration should be done at open outdoor area. The calibration process
may fail due to magnetic interference from surrounding environment.
Failing of compass calibration is indicated by 3 prominent beep sounds (3 beeps). In case
of failure:
1. Move away from magnetic interferences.
2. Disconnect the flight battery and re-connect it.
3. Restart the procedure.
■
Successfully completed calibration procedures can be skipped.
17. Flying the Navigator 250
■
Before you install the battery, turn on the transmitter. An unbound aircraft is considered
uncontrolled.
17.1 Visual inspection
■
Inspect the Navigator 250 for damage before every flight. Replace damaged
components before flying again. Only use original spare parts.
■
Ensure the motor arms are fully unfolded in flying position and the locking screw/nuts
are completely tightened.
■
Ensure the propellers can freely rotate without hitting any parts of the Navigator 250 body.
■
Observe the condition of each motor:
▬
Motor shaft
▬
Motors can freely rotate
▬
Propeller position and condition
■
Always replace defective parts immediately.
■
If you are unsure about your product’s condition consult an experienced RC pilot or
contact our customer support. Do not attempt any further flight until the Navigator 250
is fit for flight.
17.2 Placement at start position
Place the Navigator 250 on a level surface (e.g. stone floor). Take note of chapter ‘13.
Protect your model’ on page 14 .
17.3 Stick controls
Refer to chapter ‘26. Terms’ on page 34 and also study ‘14.9 Controls’ on page 21 .
17.4 Flying
D
Start with simple flight manoeuvers and gradually proceed to more challenging ones.
1. Place the Navigator 250 on even ground, wait and observe the GPS signal reception level.
When taking off without GPS signal, the Navigator 250
will land at the location where R.T.H. is triggered.
2. Turn on the motors.
3. Check proper functioning of aileron , elevator , throttle and rudder .
4. Increase throttle until the Navigator 250 is at least 50 cm above the ground.
▬
At this height, you have passed the so-called ground effect and the Navigator 250
is more stable in its flight position, thus can be controlled more easily.
▬
Be careful when applying rudder , which will rotate the Navigator 250 around
its vertical centre axis, causing you to become disoriented. Study carefully how
aileron and elevator behave after applying rudder.
5. You have now managed the critical part and can familiarize yourself with the
Navigator 250 by gentle throttle motions.
6. To land, decrease the throttle slightly until it gravitates to the ground.
▬
A somewhat solid touchdown is no problem and should not be corrected with
jerky throttle movements.
▬
Attempt to touch down vertically (“helicopter landing”). Avoid landing with high
horizontal speeds (“airplane landing”) to prevent the legs from getting entangled,
resulting in the Navigator 250 tumbling.
7. After landing, turn off the motors.
8. Disconnect the battery.
