This menu is intended for fi xed-wing models only, and
is used to determine the trim effect of the four digital
trim levers, and to “slow down” the effect of sticks 1 to
4 if desired.
Move to the relevant line with the rotary control
pressed in. Select the appropriate function fi eld, press
the rotary control briefl y, then enter the desired set-
ting in the highlighted fi eld using the rotary control.
“Trim” column
With the exception of “Channel 1”, the trim effect of
the digital trim levers can be switched from “global” to
“phase” and vice versa.
“global”: The setting of the trim lever affects the cor-
responding model over all the programmed
fl ight phases, i. e. its effect is “global”.
“phase”: The setting of the trim lever affects the mo-
del differently in each fl ight phase, and the
settings are automatically stored when you
switch fl ight phases, so that the established
setting is again available when you switch
back.
Pressing CLEAR resets this parameter to “global”.
“Tr.step” column
The four digital trim levers shift the neutral point of the
relevant stick function by one increment every time
you push (“click”) the trim lever in either direction. The
size of the increment can be varied in this menu; the
maximum trim value is always about +/-30% of the
control travel, regardless of the number of trim incre-
ments applied.
Hold the rotary control pressed in to select the appro-
priate line. Press the rotary control briefl y, then set a
value within the range 1 to 10.
(pressing CLEAR = 4)
“- time +” column
In the “Time” column it is possible to infl uence the
speed of movement of servos controlled by sticks 1 to
4; the response speed is variable separately for each
stick. The associated servo or servos still follow the
travel of the transmitter control, but with a correspon-
ding delay. This time delay affects the transmitter con-
trol signal directly, and therefore infl uences all servos
controlled by the particular transmitter control at the
same rate.
The time can be programmed SYM metrically (for both
sides) or separately for each direction of movement
(
ASY ); the available range is 0 to 9.9 seconds. For
asymmetrical adjustment move the stick to the appro-
priate side, so that the highlighted fi eld – in which the
desired value is to be entered – alternates between
the two directions.
( CLEAR = 0.0 s.)
Typical application:
If Channel 1 controls the aircraft’s motor, then it may
make sense to program an asymmetrical time delay
in order to avoid the abrupt application of full-throttle.
In contrast, safety considerations dictate that it should
always be possible to stop the motor “immediately”
(no delay).
