JR XP8103 / X3810 Setup

OPTION 1, Gear channel sets RPM

The throttle connects to THRO channel (1)

The auxiliary connects to GEAR channel (5)

ATV setup [TRVL ADJ]

Setup the throttle servo and linkage as close to +/- 100% ATV as possible.

Select the GEAR channel to +100% and -100%

Hint: You can observe the GEAR range on the [MONIT] screen

The system is now ready for calibration. Calibration Procedure

The target rotor speed can be calculated using the ATV Calculator

 

Example 1): 2 speed setup:

Gear ratio = 9.3:1

ATV- = 39%, ATV+ = 72%

 

GEAR Sw Posn             Rotor RPM

down (MIX)                 1200

up (GEAR/INVERT)     1500

 

Example 2): 1 speed setup and disable:

Gear ratio = 9.3:1

ATV- = 0%, ATV+ = 72%

 

GEAR Sw Posn             Rotor RPM

down (MIX)                 Disabled

up (GEAR/INVERT)     1500

 

Example 3): Flight Mode Mixing:

        Set the throttle curves in Flight modes 1 and 2 above the throttle priority level.

Set the GEAR switch to the (MIX) position

Set the GEAR ATV [TRVL ADJ] to -0%

Set the GEAR switch to the up (GEAR/INVERT) position

Set the GEAR ATV [TRVL ADJ] to +100%

[PROG.Mix3] - This mix disables the Governor in flight mode 'N'

GEAR->GEAR

RATE:->-100%

              0%

SW: ON, Offset 0

[PROG.Mix2] - This mix sets the target rpm to 1200rpm (39%) in flight mode '1'

GEAR->GEAR

[Select Point-H]

Set the rate to 39

[Select Point-L]

Set the rate to 0

[Ignore Point-1, Point-2 and Point-3]

SW: F-S12

[PROG.Mix1] - This mix sets the target rpm to 1500 (72% - 39% see note below) in flight mode '2'

GEAR->GEAR

[Select Point-H]

Set the rate to 33 (see note below)

[Select Point-L]

Set the rate to 0

[Ignore Point-1, Point-2 and Point-3]

SW: F-2

 

          Note: The Mix1 rate is 72 (1500rpm) - 39 (1200rpm) = 33%

    

GEAR Sw Posn         Flight Mode     Rotor RPM

down (MIX)             N                    Disabled

                                1                    Disabled

                                2                    Disabled

up (GEAR/INVERT)  N                   Disabled

                                1                     1200 rpm

                                2                    1500rpm

OPTION 2, AUX3 channel sets RPM

The throttle connects to THRO channel (1)

The auxiliary connects to AUX3 channel (8)

ATV setup [TRVL ADJ]

Setup the throttle with as much ATV range as possible.

AUX3 is already mixed to the flight mode switch. The ATV in normal flight mode is +100, in flight mode1 the ATV is 0 and in Flight mode 2 the ATV is -100.

Set the AUX3 ATV [TRVL ADJ] to +100% in N and Flight S1 and S2 switch positions.

Remove any V curves or idle up curves (they can be restored after calibration) on the throttle in S1 and S2 flight modes and put in the default curves: 0,25,50,75,100.

Inhibit any mixing on AUX 3. Toggle the flight mode switch (n - 1 - 2- 1 - n) to enter and leave calibration.

Two mixes are used to add offsets to AUX 3 in each flight mode so that, in this example, Normal mode disables the Governor, flight mode 1 sets 1200rpm and flight mode 2 sets 1500rpm.

Hint: You can observe the AUX3 range on the [MONIT] screen

[PROG.Mix1] - This mix flattens the AUX3 channel to disable the TJ in each flight mode switch position.

AUX3->AUX3

Point-L:-> 100

Point-1:-> INH

Point-2:-> 0

Point-3:-> INH

Point-H:-> -100

SW: ON

[PROG.Mix2] - This mix sets the target rpm to 1200rpm (39%) in flight mode '1' and 1500rpm (72%) in flight mode 2.

AUX3->AUX3

Point-L:-> 72 (1500 rpm in Flight mode 2)

Point-1:-> INH

Point-2:-> 39 (1200 rpm in Flight mode 1)
