when desiring to make the spin and other steering
angles large, set it to ON and adjust the horn, ad-
justers, and trimmers for level flight.
When the dual travel switch is set to OFF, kick
up is set, and the steering angle becomes large.

•Aileron, elevator, and rudder right and left (UP.

DOWN) angle adjustment

[ATV (Adjustable Travel Volume)]
The aileron, elevator, and rudder steering angles
can be made small within the range of the hatched
lines in Fig. 6.
When the aileron right roll and left roll rates are
different, they can be made the same by adjusting

the and trimmers of Fig. 2.

This also applies to the elevator and rudder. An
elevator UP and DOWN difference can also be
provided for easier flying.

The elevator ATV trimmers are

point, linkage is extremely simple.

Dual travel is operative even at elevator and flap
mixing.
Use the CH6 flap trim lever of Fig. 1 to adjust

the flap neutral position. Use this trimmer is the
same manner as a trim lever (aileron trim and
elevator trim).
Mixing is released when the MIX switch is set to
the center position (• mark). The flap neutral
position is not changed at this time.

(NOTE) Channel 6 is for the flaps, but can also be

used as a spare channel. However, since the
travel range is slightly narrow, adjust the

linkage.

•Adjustment when mixing spoiler, etc. and flaps

(When using the flaps and spoiler as an air brake)

Connect the flap servo to channel 6 of the re-

ceiver and the spoiler servo to channel 7.

of Fig. 2.

The rudder ATV trimmers are

of Fig. 2.

•Elevator and flap mixing adjustment

Connect the flap servo to channel 6 of the receiver.
When the MIX switch of Fig. 1 is set to

the elevator and flaps are mixed. Set the steering

When the MIX switch of Fig. 1 is set to

. the spoiler is mixed with the flaps. When

the CH7 switch of Fig. 1 is set to , the
spoiler and flaps are operated simultaneously.
The amount of mixing at this time is adjusted
with the trimmer of Fig. 2.
The direction and amount can also be set.
When the MIX switch is set from RELEASE
to , the flap neutral position may deviate.

If this occurs, adjust the NEUTRAL

trimmer of Fig. 2 so that the flap neutral position
does not change when the MIX switch is set to
any position.
