ADJUSTMENTS AND FLIGHT TECHNIQUES
•USING DUAL RATE
(AILERON, ELEVATOR, AND RUDDER)
Dual rate functions allow the flyer to alter the
maximum servo travel (and therefore control sensi-
tivity) during flight by using the appropriate rate
switch. At D/R OFF, servo deflection is maximum
in both directions (unless limited by ATV set-
tings). At D/R ON, servo deflection is reduced by
a percentage set with the D/R trimmers. Dual rate
adjustments always effect both directions of servo
travel.
AILERON DUAL RATE
• The aileron rate switch 14 has two D/R ON positions. Thus three different servo travel rates are available
on aileron. Rates can be adjusted to suit varying aircraft and maneuver requirements.
1 Aileron dual rate trimmer (I)
This trimmer sets the aileron travel when the aileron dual rate switch 14 is set
to the dual ON I position.
2 Aileron dual rate trimmer 2
(Switch in LINEAR Position)
Dual rate switch OFF
This trimmer sets the aileron travel
when the aileron dual rate switch
14 is set to the dual ON 2 posi-
tion.
Servo
throw
Trimmers [1] and [2] can adjust the
aileron travel from 40% to 80% of
the total travel.
When the dual rate switch is set to
ON, the servo throw can be set to
an arbitary angle smaller than
when the dual rate switch is OFF
(normal) as shown in Fig. 27. Use
the throw matched to the aircraft
and the maneuvers to be perform-
ed.
Stick deflection
When the dual rate switch
is ON, the servo throw can be
adjusted within this range with
the dual rate trimmers.
N
3 LINEAR ->VTR selector
This switch linearly switches the
aileron servo when the aileron dual
rate switch 14 is in the OFF posi-
tion.

23 Elevator dual rate trimmer
This trimmer sets the elevator
deflection angle when the el-
evator dual rate switch 15 is
in the ON position. It has the
same functions as (A) aileron
dual rate I .
24 LINEAR ->VTR selector
This switch changes the eleva-
tor servo operation linearity
when the selector dual rate
switch 15 is in the OFF po-
sition. It has the same func-
tions as (A) aileron dual rate(I),
21 Rudder dual rate trimmer
This trimmer sets the rudder
deflection angle when the
rudder dual rate switch 16 is
in the ON position. It has the
same functions as (A) aileron
dual rate I .
22 LINEAR -> VTR selector
This switch changes the rud-
der servo operating linearity
when the rudder dual rate
switch 16 is in the OFF po-
sition. It has the same func-
tions as (A) aileron dual rate(I).
