Trimming; Selecting A Flight Mode; Gps Mode; Basic Mode - RC Logger 88016RC (RtF) Operating Instructions Manual

17.4.1 Trimming

■
Trimming allows you to equalize drifting. Drifting refers to movement out of position
when in hover flight without aileron or elevator input.
■
Refer to the transmitter's operating instructions for more information.

18. Selecting a flight mode

18.1 GPS mode

In the GPS mode the Navigator 250 holds a set position (x, y, and z-axis). The GPS
function controls and makes adjustments to all three axes.
1. Activate the Basic mode.
2. Lift the Navigator 250 up to the desired altitude and position it. Move the throttle
towards its centre position.
3. Activate the GPS mode on your transmitter.
4. The Navigator 250 now holds horizontal position and altitude.
5. Correct the position as desired.
6. Change flight modes to deactivate the GPS mode.
The GPS signal strength is indicated by the rear LEDs. Depending on the GPS signal
strength the solid LED is interrupted by distinct blink patterns, which are summarized in
»Fig. 12. The lower the blinking frequency, the better the GPS signal.

18.2 Basic mode

■
The basic mode is designed specifically for users who are new to flying multirotor
systems and those who look for intuitive controls for aerial photography.
■
The controls respond less aggressively. This behaviour is intentional, allowing pilots to
get a first feeling of how the Navigator 250 responds to lever input.
■
Auto-Levelling is enabled. It means that if the pilot lets go of the aileron and elevator
control stick, the Navigator 250 regains a relative horizontal level position. Small drifts
in any direction are normal, especially during not fully calm conditions.
■
We recommend this mode when you intend to use a camera or FPV equipment. Motor
power is restricted for smoother operation and less aggressive behaviour, which is
beneficial to scenery capture.

18.3 Expert mode

The Expert mode unleashes the full potential of the Navigator 250. Banking angles and
power output are significantly increased, the acceleration sensor is deactivated, allowing
fully pilot controlled flipping and rolling.
This mode is designed for pilots who have fully gained experience and confidence with
flying the Navigator 250. It allows fast passes, loops, rolls, flips at the pilot's own ability
since control functions such as auto-levelling are completely disabled.

18.3.1 Summary:

■
Expert mode is not designed for confined indoor flying.
■
Expert mode is ideal for pilot controlled acrobatic fun and aggressive FPV flying.
■
GPS Position Hold is disabled.
■
Altitude Height Hold function (Mid-stick mode throttle control) is disabled.
■
Auto-levelling is disabled.
