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.

! 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
servo to servo
The offs
shifts the cen-
tre of the
servo(s). The
travels for both
directions of
rotation are the
same (as in )
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.
