travel
Servo travel
Trv
The control surface travel is sym-
metrical, i.e. the same on both sides.
Example: ailerons
Different values for up-travel and down-travel can be
set using the Differential function.

Example: six-flap wing

! The total servo travel is the sum of trv and offs.
Example: ailerons as landing aid
If ailerons are to be raised for landing, in most cases
as much up-deflection as possible is desirable. The
down-travel is small, so the working range of the
servo around the neutral position of the ailerons is dif-
ferent. An Offset is used to avoid the necessity for
travel reductions.

Example:
Non-linear throttle compensation for elevator
Less compensation (down-elevator) is required from
idle to half-throttle (
pt1) than for the range from half-
throttle to full-throttle (
pt2).
The parameter
trv defines the
travels for both
directions of
servo rotation,
starting from the
transmitter con-
trol centre.
The input alters
the direction of
rotation from ser-
vo to servo
The
offs
shifts the cen-
tre of the ser-
vo(s). The trav-
els for both di-
rections of rota-
tion are the
same (as in c)
dead. (dead-
band) defines
how far the con-
trol must be
moved before
the effect takes
force. Servo
travels for both
directions are
the same.
The travel
(
trv) can be
set to different
values for each
direction of ro-
tation of the
servo(s).
Starting from
the idle posi-
tion of the
transmitter
control, the
servo moves
only in one di-
rection.
offs defines
the starting
point (= idle
position of the
servo),
trv
defines servo
target point for
the control
end-point.
pt1 and pt2
determine the
servo positions
for the centre
and end-points
of the trans-
mitter control.
