FUTABA 2PKA Instruction Manual page 3

The servo reversing switches are assumed to be in the normal
position in the descriptions in this section. When the servo
switches are in the reverse position, operation is the opposite
of that described here.
(1) Steering wheel (rudder)
Steering (rudder) operation.
(2) Throttle trigger (throttle lever)
Engine control/motor control operation.
The throttle neutral position can be set to one of three position by
turning the 8 throttle neutral adjuster w i t h a coin as shown in
Fig. 5. Set it to match the application.
When set to 1 ) the full deflection angle is 40°
When set to 2 ) the throttle throw is 27° and the
brake deflection angle is 13°.
When set to 3 ) the throttle and brake (reverse)
throws are both 20°.
• For engine cars, position 2 is recommended.
• For electric cars, position 3 is recommended when equipped
with reverse mechanism and position 2 is recommended when
equipped with a brake and forward only
(3) Steering trim
Steering (rudder) trim
(4) Steering rate adjuster
The steering servo steering angle can be freely set as shown in Fig. 6
with a ratcheted adjuster installed which enables you to adjust steer-
ing servo travel volume to match a car to the course, even while run-
ning.
The steering angle can be
set within this range.
30%~100%
(5) Throttle trim knob
(6) Throttle ATV high side trimmer ATV... Adjustable Travel Volume.
(7) Throttle ATV low side trimmer
Throttle ATV is a device which permits independent adjustment of
the throttle servo left and right sides (from neutral) as shown in Fig.
7 with trimmers (6) and (7). (FP-T2PKA)
ATV is the abbreviation
for Adjustable Throttle
Volume and is an extreme-
ly convenient device by
which steering servo travel
volume can be adjusted
freely with two trimmers
preloaded.
The relationship between
two trimmers does not
change even when servo is
reversed.
(6)&(7):only for FP-T2PKA.

(8) Throttle neutral adjuster
This adjuster sets the throttle trigger neutral point as described in (2)
throttle trigger. Set it to the point at which it stops with a click
with a screwdriver, coin, etc.
9 Steering (rudder) servo reversing switch
10 Throttle servo reversing switch
(11) Wheel angle adjuster
The wheel angle adjuster changes the operating angle of the (1) Steer-
ing wheel as shown in Fig. 8.
(12) Wheel tension adjuster
This is a phillips head screw which adjusts the steering force of the
steering wheel.
(13) Power switch
When set in the direction of the A mark (upper position), the switch
is turned on and the pointer of the level meter deflects.
(14) Level meter
When the 13) power switch is set to ON, the level meter pointer
should deflect to within the silver zone. If the pointer stops near the
boundary between the silver and red zones, the battery is low, and
the range of the radiowaves will be short. When the level meter
pointer drops to the boundary between the silver and red zones,
change the battery.
(15) Antenna
95cm antenna. It screws in vertically as shown in Fig. 10.
Remove from
the holder and
screw in vertically.
(16) Battery cover
When loading (or changing) the eight penlight batteries, remove this
cover as shown in Fig. 2.
(17) Transmitter crystal
When changing the frequency, replace this crystal. Use the AM crys-
tal set (transmit and receive 1 pair) sold by Futaba. The transmitter
crystal is marked TX and the receiver crystal is marked RX. However,
you are not allowed to change frequency by merely replacing crystal
on both 72 and 75MHz.
