Hovering Throttle Knob Setting
The hovering throttle knob increases or decreases the engine output power for either the center point only (point #2), or middle three (3) points, if activated, of the throttle curve. As shown in the figures below, use of the hovering throttle knob shifts the middle curve upward or downward. Therefore, operation of the hovering throttle knob does not cause any change to the high point and low point of the throttle curve.

Exponential Throttle Curve Function
With the XP8103 system, individual throttle curves are selectable to be either straight (linear) or curved (exponential). To select an exponential curve, press either of the CH keys until EXP OFF appears on the throttle curve screen. Next press either the + or key to activate the exponential feature (an "on" will replace the "off" on the screen). With the exponential function ON, you will notice that any "sharp" angles of the throttle curve will become more "rounded" or "smooth, " creating a more equal throttle servo movement during the entire throttle curve range.

Idle Up
Normally, flight mode 1 and 2 are used to increase engine RPM below half stick for forward flight maneuvers (idle up), and at this time any other trims are not active as the throttle will only operate/follow the current throttle curve values.

4. 9 Pitch Curve (Function Mode)
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.

Example of Throttle Curve and Pitch Curve Settings
An example of throttle curve and pitch curve settings for aerobatic specifications are shown below in the form of graphs. Details of the curves will differ, depending on the helicopter specifications. In these examples, the throttle open-close stroke and autorotation pitch stroke are set from 0 to 100.

4. 1 Inverted Switch (Function Mode) 0
The purpose of the Inverted Switch Function is to electronically reverse several control directions to enable you to fly a helicopter much more easily inverted. When the inverted switch is pulled down, the inverted flight function is switched ON. If you do not intend to use the inverted function, leave this operation inhibited. In the Function Mode, use the UP and DN keys to select Inverted Switch and access by pressing the UP and DN keys simultaneously. [. . . ] Most common is to drop the wing tailing edge with up Elevator.
Options and Program Ideas
With some time to experiment and learn the transmitter, you will discover a number of other ways to apply the above functions. If you fly with the aileron/rudder mix always ON, the mix switch can be used as another switch option. The available programmable mixes also allow for a variety of scale and special-use functions.
Flaperons
Following are guidelines for mixing flaps to follow aileron movement. This mix will work as part of the Launch and/or reflex preset at your option. [. . . ]
