POSITION
SERVO TRAVEL
Reversing the direction of servo rotation.
The set servo rotation is shown in the display for all
servo functions 1…8; you will see the cursor line
under either “REV” or “NORM”. This eliminates the
need to reconnect plugs in the transmitter or reverse
the servos themselves. Press the CH SEL button
repeatedly until the required channel you wish to
alter appears in the display, then swap the direction
using the INC or DEC buttons. The CLEAR button
will always reset the direction to “NORM”.
Note
:
The channel number refers to the receiver output to
which the servo in question is connected. Any
agreement with the numbering of the channel inputs
is coincidental, and is unlikely to be the case when
complex mixes are in use. For this reason a change
in stick mode does not affect the numbering and
direction of rotation of the servos.
This can be used to adjust for non-standard pulse
width servos (≠1.5ms) or other reasons.
The neutral position can be shifted within the range
±125 steps (approximately 70% travel) using the
“SB TRIM” option, regardless of the trim lever
position and any mixer settings.
Select the channel you want to adjust using the
CH SEL button and then press INC or DEC
repeatedly to shift the centre point, until the servo
neutral is correct for you application. The CLEAR
button can be used to reset the adjustment to 0, i.e.
the servo the return to its original neutral position.
This setting refers directly to the servo concerned,
and is not affected by other trim and mixer settings.
The abbreviation “TRV ADJ” stands for Travel Adjust
and provides adjustment of servo travel separately
for either side of centre. The adjustment range is
0…160% of normal servo travel.
It can be determined from the block diagram what
impact this setting has on the servo concerned.
Some mixers are not affected by this setting as they
feed directly into the „Input Point for Mixers“, whilst
the output of others are adjusted according to this
setting.
Press the CH SEL button repeatedly until the correct
servo function (1…8) appears in the display. The
bottom line of the display shows the servo travel set,
with the prefix (+ or -) indicating the side of centre. If
you wish to adjust (& display) a setting, you need to
move the associated control (stick, slider, switch) to
the relevant end-point. Adjust the travel with the INC
or DEC buttons, and reset it to 100% with CLEAR .
