17. This trimmer sets
rudder servo throw and
direction when the rudder
button [33] is set to ON
(pressed). The servo throw
can be adjusted up to the
total travel.
18. Rudder time trimmer
This trimmer sets the time
the rudder servo stops at a
fixed deflection when the
rudder button [33] is pres-
sed. A time from 0 to
about 3 seconds can be set.
19. Rudder button fail safe

ates. When it is set to the
INH side, the rudder but-
ton becomes inoperative.
20. Rudder dual rate trimmer
This trimmer adjusts the
rudder servo throw when
the rudder dual rate switch
[ 1 6] is set to ON. It has the
same functions as the ailer-

F. 2nd ATV
ATV is the abbreviation of Adjustable Travel Volume.
It is a device which allows independent adjustment of
the servo left and right (up and down) throw without
affecting the neutral position. Because of the engine
torque, precision of the model, and for other reasons,
the radius of left and right turns is always different
even if the left and right steering throws are perfectly
matched. The A T V is most convenient when left turns
are good, but right turns are to sharp. In this case, left
and right turns of the same radius can be easily made
by reducing the servo right throw slightly. The aileron
and elevator 2nd ATV is the conventional trimmer
type ATV.

can be turned on and off
separately.
•When this switch is set to
the COMB position, the
aileron and elevator dual
rates can be turned on and
off simultaneously with the
aileron dual rate switch [14].
Set it to the position you
