Transmitter Setup

IMPORTANT: The included AR636 receiver has been programmed for opera-
tion in only this aircraft.

A DSM2/DSMX four-channel (or better) transmitter with dual rates is required
for fl ying this aircraft. The Spektrum

DX6i, DX6, DX7s, DX8, DX9, DX10t,

DX18 and JR

®

X9503, 11X or 12X transmitters may be used.

A DSM2/DSMX computerized transmitter with adjustable dual rates and expo
is recommended for the best fl ight performance of this aircraft.

9 Transmitter Setup Checklist

Before binding your Computerized Transmitter (DX6i, DX6, DX7/DX7se,
DX7s, DX8, DX9, DX10t, DX18):

1. Choose a blank model memory with only default (zero) settings

(including trim and sub-trim).

After binding:

1. Check and adjust the servos so each arm’s neutral position is

perpendicular or as close to 90° as possible (loosen and adjust the
servo arm splines on the servo only when needed). DO NOT use
sub-trims to make fi ne adjustments, off-center sub-trim will affect
servo travel and AS3X operation.

2. Adjust linkage lengths so the control surfaces center when the

servo arm is close to perpendicular.

3. Set rates in the transmitter as recommended.

CAUTION: For safe operation, always re-bind the airplane after setup
is complete to ensure the failsafe is updated with the latest setup.

Control Surface Centering

IMPORTANT: Perform the Control Direction Test before performing control
surface centering.

Control Surface Centering and Adjusting a Linkage

While AS3X

®

technology is inactive (before advancing the throttle), mechani-

cally center the control surfaces.

After binding a transmitter to the airplane’s receiver, set the trims and sub-
trims to 0, ensure the servo arms are in the correct positions, then adjust the
linkages to center the control surfaces.

Tip: Use needle-nose pliers or ball link pliers (RVO1005) to remove or install a
link on a control horn.

• Turn the linkage clock-

wise or counterclockwise
until the control surface is
centered.

• Attach the linkage to the

servo arm or control horn
after adjustment.

Trimming

IMPORTANT: Only trim this aircraft in AS3X Precision Flight Mode.

After adjusting transmitter trim in the air or on the ground, do not touch the
control sticks for 2 seconds
. This allows the receiver to learn the correct
settings to optimize AS3X performance.

Failure to do so could affect fl ight performance.

Transmitters DX6i and Above

Servo travel ......................................................................................100%

Always leave servo travel at 100%. Although the fl ight modes are factory set,
it is strongly recomended that dual rates and expo are also used to further
reduce control sensitivity for fi rst fl ights.

If you are a less experienced pilot we strongly recommend adjusting rates and
expo to these settings.

Take fi rst fl ights in low rate.
