Transmitter Setup
†Some of the terminology and function locations used in the iX series programming may be
slightly different than other Spektrum™AirWare™radios. The names given in parenthesis
correspond to the iX series programming terminology. Consult your transmitter manual for
specific information about programming your transmitter.
‡The settings provided above for the DX6 and DX6e do not allow for the use of a SAFE®Select
switch. To use a SAFE Select switch on these systems see the SAFE Select Switch Designation
section for transmitter setup and operation information.
IMPORTANT: After you set up your model, always rebind the transmitter and
receiver to set the desired failsafe positions.
IMPORTANT: Flap to elevator mix values, control throws, dual rates, exponential,
CG range are recommended as STARTING POINTS and should be adjusted for
personal preference as/if needed after making initial flights.
If your transmitter allows it, enable the throttle cut feature. Always engage throttle
cut before approaching the aircraft.
Dual Rates
Low rate is recommended for the initial flights.
NOTICE: To ensure AS3X®technology functions properly, do not lower rate
values below 50%. If lower rates are desired, manually adjust the position of the
pushrods on the servo arm.
NOTICE: If oscillation occurs at high speed, refer to the Troubleshooting Guide
for more information.
Exponential
After first flights, you may adjust exponential in your transmitter.
Transmitter Telemetry Setup

4. Insert the Z-bend end of the elevator push rod in the middle hole of the
elevator servo arm, as shown.
5. Attach the clevis end to the second outermost hole of the elevator control horn.
CAUTION: Ensure the rubber retention sleeve is properly installed on the
clevis. Failure to properly install the sleeve may allow the clevis to open
in flight, causing a loss of control of the aircraft
Wing Installation
1. Insert the longer of the two wing tubes in the front hole of the wing root of one
of the wing panels.
2. Insert the shorter tube in the rear hole of the wing root.
3. Slide the opposite wing panel onto the wing tubes until the panels meet at the
wing root. Ensure the aileron, flap, LED and gear servo wires pass through the
square hole to the top of the wing.

Center of Gravity (CG)
Battery Installation and ESC Arming
The CG location is measured from the leading edge of the wing, where the wing
meets the fuselage. Measure the CG location with the recommended battery
(SPMX56S30) installed, with the model balanced inverted and the landing gear
extended. Adjust the battery forward or aft as needed to achieve the proper CG
location. 180mm (+/– 5mm) behind the leading edge
of the wing where it meets the fuselage.
We recommend the Spektrum™5000mAh 6S 22.2V Smart G2 30C (SPMX56S30).
Refer to the Optional Parts List for additional recommended batteries. If using a
battery other than those listed, the battery should be within the range of capacity,
dimensions and weight of the recommended battery packs to fit in the fuselage.
Ensure the model balances at the recommended CG.
CAUTION: Always keep hands away from the propeller. When armed, the
motor will turn the propeller in response to any throttle movement.
1. Lower the throttle and throttle trim on the transmitter to the lowest settings.
Power on the transmitter, then wait 5 seconds.
2. Apply the loop side of hook and loop tape to the bottom of your battery. The
hook material is pre-installed in the battery compartment.
3. Pull back on the release button and remove the battery hatch.
4. Install the fully charged battery in the battery compartment as shown. See the
Center of Gravity section for how to achieve proper balance of the aircraft.

Transmitter and Receiver Binding / Switching ON and OFF SAFE Select
The BNF Basic version of this airplane includes SAFE Select technology, enabling you to choose the level of flight protection. SAFE mode includes angle limits and
automatic self leveling. AS3X mode provides the pilot with a direct response to the control sticks. SAFE Select is enabled or disabled during the bind process. With SAFE
Select disabled the aircraft is always in AS3X mode. With SAFE Select enabled the aircraft will be in SAFE Select mode all the time, or you can assign a switch to toggle
between SAFE Select and AS3X modes.
Thanks to SAFE Select technology, this aircraft can be configured for full-time SAFE mode, full-time AS3X mode, or mode selection can be assigned to a switch.
IMPORTANT: Before binding, read the transmitter setup section in this manual and complete the transmitter setup table to ensure your transmitter is properly
programmed for this aircraft.
IMPORTANT: Move the transmitter flight controls (rudder, elevators, and ailerons) and the throttle trim to neutral. Move the throttle to low before and during binding.
This process defines the failsafe settings.
You can use either the bind button on the receiver case OR a conventional bind plug to complete the binding and SAFE Select process.
• The included receiver has been specifically programmed for operation of this
aircraft. Refer to the receiver manual for correct setup if the receiver is replaced.
• Keep away from large metal objects while binding.
• Do not point the transmitter’s antenna directly at the receiver while binding.
• The orange LED on the receiver will flash rapidly when the receiver enters
bind mode.
• Once bound, the receiver will retain its bind settings for that transmitter until
you re-bind.
• If the receiver loses transmitter communication, the failsafe will activate.
Failsafe moves the throttle channel to low throttle. Pitch and roll channels move
to actively stabilize the aircraft in a descending turn.
• If problems occur, refer to the troubleshooting guide or if needed, contact the
appropriate Horizon Product Support office.
