A
djustment of the pitch curve is very similar to the throttle cur ve
adjustment described in the preceding section. A thorough
understanding of the throttle cur ve section will make pitch cur ve
adjustment easier to understand.
The XP8 10 3 of fers four (4) independent types of pitch cur ves:
Nor mal, Stunt 1, Stunt 2 and Hold. Each pitch cur ve contains
five (5) adjustable points — L, 1, 2, 3, and H. Note: When
setting pitch cur ve for throttle hold, it is necessar y for the throttle
hold to be active — if this function is inhibited, the throttle hold
pitch cur ve will not be visible on the screen.
In the Function Mode, use the UP and DN keys to select Pitch
Cur
ve 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 Nor mal, position, and its function is to shift either the
center point only (#2) or the middle three (3) points (if activated)
of the cur ve either upward or downward to adjust rotor RPM at
the hover position.
Pitch T rim 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.

point is activated,
