Transmitter Setup
†Some of the terminology and function locations used in the iX12 programming may
be slightly different than other Spektrum AirWare™ radios. The names given in
parenthesis correspond to the iX12 programming terminology. Consult your transmitter
manual for specic information about programming your transmitter.
* Flap programming values may vary slightly. For your initial ights use the
recommended ap travel settings provided in the Flaps section and adjust the
ap travel to your preference on subsequent ights.
‡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 section below 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: The included receiver has been programmed specically for
operation in this aircraft. If you desire to use the AR637T receiver in a different
aircraft visit spektrumrc.com for reprogramming instructions.
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 ights.
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.
Expo
After rst ights, you may adjust expo in your transmitter.

Horizontal Tail Installation
1. Slide the horizontal tail into the tail opening in the rear of the fuselage.
Ensure the control horn faces down.
2. Center the horizontal tail and then secure into place using the 3 included
(3x40mm) screws (A).
3. Connect the z-bend end of the control linkage to the second hole of the servo
arm (B).
4. Connect the ball link (C) to the ball (D) installed on the elevator’s control horn
using pliers or ball link pliers. Ensure the elevator servo arm is in the correct
position.
When needed, disassemble in reverse order.

Propeller Installation
WARNING: Do not install the propeller until all system setups are
complete. Failure to heed this warning could result in severe personal
injury.
1. Install the 4 propeller blades (A) onto the spinner backplate (B) using 8
screws (3x20mm) (C) and 8 nuts (D). The propeller’s yellow tips must face
out from the motor for correct propeller operation.
2. Install the spinner backplate onto the propeller shaft (E). Make sure the hex of
the backplate properly seats into the hex at the base of the propeller shaft.
3. Install the propeller washer (F) and spinner nut (G) onto the propeller shaft.
Secure the propeller assembly into place by tightening the spinner nut with
a wrench.
4. Align and install the spinner (H) with a screw (3x30mm) (I).

Optional Drop Tank Installation
The recommended receiver for this aircraft is the Spektrum AR637T. If you
choose to install a different receiver, ensure that it is at least a 6-channel
full range eceiver. Refer to the manual of your chosen receiver for correct
installation and operation instructions.
AR637T Installation
1. Slide the canopy latch (A) back and lift the back of the canopy to remove
the canopy from the fuselage.
2. Attach the appropriate control surfaces to the their respective ports on the
receiver using the table at the right.
3. Using double-sided servo tape,(not included) mount the receiver to the at
area behind the battery compartment, as shown. The receiver should be
mounted in the orientation shown, parallel to the length of the fuselage,
with the label facing up and the servo ports facing the front of the
aircraft. The orientation of the receiver is critical for all AS3X®and SAFE®
technology setups.
CAUTION: Incorrect installation of the receiver could cause a crash.

Drop Tank
Slide the optional drop tanks (A) into the rails (B) on the bottom of the left and
right outer wing panels.
TIP: The drop tanks are labeled (L) for left and (R) for right.
Check the Center of Gravity with the drop tanks installed.
See the Adjusting the Center of Gravity instructions for more information.

Battery Selection
We recommend the 5000mAh 22.2V 6S 30C Li-Po battery (SPMX50006S30).
Refer to the Optional Parts List for other recommended batteries. If using
a battery other than those listed, the battery should be within the range of
capacity, dimensions and weight of the Spektrum Smart Li-Po battery packs to
t in the fuselage. Be sure the model balances at the recommended CG.
1. Lower the throttle to the lowest settings. Power on the Transmitter, then
wait 5 seconds.
2. Slide the canopy latch back and lift the back of the canopy (A) to remove.
3. Slide the battery tray (B) out of the battery compartment.
4. For added security apply the loop side (soft side) of the optional hook and loop
tape (C) to the bottom of your battery and the hook side to the battery tray.
5. Install a fully charged battery (D) on the front edge of the battery tray as
shown and secure it using the hook and loop straps (E).
6. Align the battery tray with the tracks in the battery compartment and slide
the tray all the way forward until the tray locks.
7. Connect the battery to the ESC (the ESC is now armed).
8. Keep the aircraft immobile and away from wind or the system will not
initialize.
• The ESC will sound a series of tones (refer to step 6 of the binding
instructions for more information).
• An LED will light on the receiver.
If the ESC sounds a continuous double beep after the ight battery is
connected, recharge or replace the battery.
9. Reinstall the canopy hatch.
WARNING: Always keep hands away from the propeller. When armed,
the motor will turn the propeller in response to any throttle
movement.
WARNING: If your transmitter supports it, always engage throttle cut
before approaching the aircraft any time a battery is connected.

IMPORTANT: Perform the Control Direction Test before performing control
surface centering.
While SAFE is inactive (before advancing the throttle), mechanically center the
control surfaces.
IMPORTANT: Correct operation of the SAFE system requires sub-trim and trim
at 0.
After binding a transmitter to the airplanes 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. • Turn the linkage clockwise
or counterclockwise until the
control surface is centered.
• Attach the linkage to the
servo arm or control horn
after adjustment
The table to the right shows the factory settings for the control horns and servo
arms. Fly the aircraft at factory settings before making changes.
NOTICE: If control throws are changed from the factory settings, the AR637T
gain values may need to be adjusted. Refer to the Spektrum AR637T manual
for adjustment of gain values.
After ying, you may choose to adjust the linkage positions for the desired
control response. See the table to the right.
