HELI 81
Adjustment of the pitch curve is very similar to the throttle curve
adjustment described in the preceding section. A thorough
understanding of the throttle curve section will make pitch curve
adjustment easier to understand.
The XP8103 offers four (4) independent types of pitch curves:
Normal, Stunt 1, Stunt 2 and Hold. Each pitch curve contains
five (5) adjustable points — L, 1, 2, 3, and H. Note: When
setting pitch curve for throttle hold, it is necessary for the throttle
hold to be active — if this function is inhibited, the throttle hold
pitch curve will not be visible on the screen.
In the Function Mode, use the UP and DN keys to select Pitch
Curve and access by pressing the UP and DN keys
simultaneously.
Hovering Pitch Knob
The hovering pitch knob operates in the same manner as the
hovering throttle knob. It is operable while the flight mode is in
the N, or Normal, position, and its function is to shift either the
center point only (#2) or the middle three (3) points (if activated)
of the curve either upward or downward to adjust rotor RPM at
the hover position.
Pitch Trim Knob
The pitch trim knob is a trimmer for the pitch channel. This knob
should be set to 0, and all changes upward or downward
should be made from this neutral point. This function is used to
adjust the main rotor speed (RPM) to stay within manufacturer’s
specifications. If the pitch curve is set properly, only small trim
adjustments will be required.
