Transmitter Setup
IMPORTANT: Set up your transmitter before binding
your transmitter to the aircraft.
Before binding a non-computerized transmitter,
ensure all servo reversing is set to normal and trim
is at center.
Dual Rates and Expo
After fi rst fl ights, you may adjust Dual Rates
and Expo in your transmitter or refer to the
AR6335 receiver manual for Dual Rates and Expo
adjustment.
Computerized Transmitter Setup
(DX6i, DX6, DX7S, DX8, DX9, DX10t and DX18)
Start all transmitter programming with a blank
ACRO model (do a model reset), then name the
model. Leave all settings at default.
DX6i only: Reverse channel 5.
IMPORTANT: After you set up your model, always
rebind the transmitter and receiver to set the
desired failsafe positions.
Flight Modes
The installed AR6335 receiver has been
programmed for operation specifi cally in this
aircraft, providing the following selectable fl ight
modes.
The fl ight modes can be changed using the Gear/
Channel 5 Switch.
Selecting Flight Modes may vary depending on
your transmitter’s Gear / Channel 5 switch type (2
position or 3 position). Refer to the provided charts
to fully understand how your transmitter switches
will operate this aircraft.
IMPORTANT: It is recommended to take fi rst fl ights
in Precision Mode (Low Rate).
Precision Mode
This mode uses low rates and low gains to deliver
precise response at high airspeeds. Use this mode
to trim the aircraft and fl y fast precision maneuvers.
3D Mode
This mode uses high rates and high gains to deliver
extreme maneuverability with maximum stability at
low airspeeds. Use this mode for slow fl ying and 3D
maneuvers such as Hovers and Harriers. Flying at
high speed in this mode will cause oscillation.
NOTICE: If oscillation occurs at high speed, refer to
the Troubleshooting Guide for more information.
Quickstart
1. Set a Blank model. (DX6i only: reverse
channel 5)
2. Bind
3. Choose a Flight Mode = Gear / Ch 5
(Start with Precision Mode)
4. Go fly
2 Position Gear/Ch 5 Switch Transmitters
Precision Mode (Low Rate)
Position 0 is Precision
Mode
3D Mode (High Rate)
Position 1 is 3D Mode
3 Position Gear/Ch 5 Switch Transmitters
Precision Mode (Low Rate)
Positions 0 and
1 are Precision
Mode
3D Mode (High Rate)
Position 2 is 3D
Mode
Tip: If desired, assign Gear / Channel 5 to a
2-position switch of your choice. Refer to your
computerized transmitter manual for switch
assignment instructions.

Prefl ight Checklist
EN
1. Charge fl ight battery.
2. Install fl ight battery in aircraft (once it has
been fully charged).
3. Bind aircraft to transmitter.
4. Make sure linkages move freely.
5. Perform Control Direction Test with
transmitter.
Assembly
Required Adhesives:
foam-compatible
Medium CA
Wing Installation
1. Put the wing servo connectors into the hole in
the bottom of the fuselage.
Tip: If needed, use hemostats or pliers to
pull the servo connectors into the fuselage.
CAUTION: DO NOT crush or otherwise
damage the wiring when attaching the wing
to the fuselage.
6. Adjust center of gravity.
7. Perform a radio system Range Check.
8. Find a safe and open area.
9. Plan fl ight for fl ying fi eld conditions.
2. Apply foam-compatible medium CA to the
center section of the lower wing, and attach it
to the under side of the fuselage.
3. Place the upper wing cabane rods fully in the
fuselage mounts. Do not glue at this moment.
5
EN
4. Apply foam-compatible medium CA to the strut
mounting slots on both wings. Slide the left
and right struts in the slots between the wings
as shown. Make sure the wings are straight,
level and parallel with each other.
The blue graphic
should be at the top
of the strut with the
decal at the bottom
facing out.
5. Secure the top wing to the fuselage by
applying foam-compatible medium CA where
the upper wing cabane rods meet the fuselage
mounts.
6. When the foam-compatible CA is dry, connect
the left and right linkages between the ailerons
as shown.
7. Remove the battery hatch.
8. Connect the aileron servos from the wings
to the Y-harness connectors in the
fuselage. The left and right aileron servos
can be connected to either side of the
Y-harness.
IMPORTANT: Correct operation of the AS3X
system requires connection of both ailerons to
the included Y-harness and the AILE channel of
the receiver.
NOTICE: When disconnecting the servo connectors, do not pull on the servo wires. Use a
screwdriver or pliers to break the friction fi t of the
servo connectors. Failure to do so could result in
damage to the servo wiring.
