Calibration procedure
CH 4 – Lt Flap
Start by calibrating left flap (CH4). The goal is (a) set the end points, and
(b) linearise the response.
Note:
the flap neutral will be adjusted later.
1.
Enter CAL mode
2.
Set switch
SA
to middle position
3.
In the
OUTPUTS
menu, highlight CH4
4.
Skip to curve field CV14, and press
{long
ENTER
} to open curve editor
5.
Throttle stick fully back (↓), adjust point 1 for lower end point. Allow for
both crow and aileron inputs.
6.
Throttle stick fully forward (↑), adjust point 3 for upper end point. Allow
for any aileron-to-flap mixing.
7.
Adjust point 2 so it lies on the straight line thru points 1 and 3.
8.
Move throttle stick from one end to the other, observing step intervals.
You can fine tune point 2 to equalise intervals for best linearity.
CH 3 – Rt Flap
Next, calibrate the right flap (CH3). The goal is to precisely match the left flap.
1.
Enter CAL mode
2.
Set switch
SA
to middle position
3.
In the
OUTPUTS
menu, highlight CH3
4.
Skip to curve field CV13, press
{long
ENTER
}
to open curve editor
Adjust points 1 – 5 to exactly match the left flap:
5.
stick fully back, adjust point 1
6.
stick ½-back, adjust point 2
7.
stick to centre, adjust point 3
8.
stick to ½-forward, adjust point 4
9.
stick fully forward, adjust point 5
To match the end points on left and right sides, it may be necessary to reduce
one or other end points for the left flap.
Flap neutral
Next, set the flap neutral:
1.
Enter CAL mode
2.
Set switch
SA
to down position. An adjustable offset is applied to each
flap.
3.
Open the
GLOBAL VARIABLES
menu.
4.
Highlight GV4(‘FlNeut’) and skip to the FM0 column.
5.
Adjust GV4 for correct neutral.
Check that the flaps are perfectly in line at the neutral position. If not, then
check calibration of the right flap (see previous step), paying particular
attention to the 2 points either side of the the neutral position.
V-Tail
CH 5 – RtVee
CH 6 – LtVee
Calibrate V-tail surfaces:
1.
Enter CAL mode
2.
In the
OUTPUTS
menu, highlight CH5
3.
Skip to curve field ‘CV15’, press
{long
ENTER
}
to open curve editor
4.
Ele stick to centre, adjust point 2 for correct neutral
5.
Ele stick forward (↑), set point 3 to upper limit
6.
Ele stick back (↓), set point 1 to lower limit. Allow for spoiler comp.
7.
Repeat for CH6/CV16, ensuring that movements match CH5.
8.
Check equal travel up/down; left and right surfaces match
