SAFE® Select Technology (BNF Basic)

The BNF Basic version of this airplane includes SAFE Select technology which can offer an extra level of protection in ﬂight. Use the following instructions to make the SAFE Select system active and assign it to a switch. When enabled, SAFE Select prevents the airplane from banking or pitching past predetermined limits, and automatic self-leveling keeps the airplane ﬂying in a straight and level attitude when the aileron, elevator and rudder sticks are at neutral.

SAFE Select is enabled or disabled during the bind process. When the airplane is bound with SAFE Select enabled, a switch can be assigned to toggle between SAFE Select mode and AS3X mode. AS3X® technology remains active with no banking limits or self leveling any time SAFE Select is disabled or OFF.

Preﬂight

SAFE Select can be conﬁgured three ways:

• SAFE Select Off: Always in AS3X mode

• SAFE Select On with no switch assigned: Always in SAFE Select mode

• SAFE Select On with a switch assigned: Assigned switch toggles between SAFE Select mode and AS3X mode

1 Remove and inspect contents. 2 Read this instruction manual thoroughly. 3 Charge the ﬂight battery. 4 Set up the transmitter using transmitter setup chart. 5 Fully assemble the airplane. 6 Install the ﬂight battery in the aircraft (once it has been fully charged). 7 Check the Center of Gravity (CG). 8 Bind the aircraft to your transmitter.

Model Assembly

Landing Gear Installation

1. Remove the screw (2mm x 15mm) on the bottom of the fuselage and remove the landing gear cover.

2. Install the six mounting screws (2mm x 10mm) and three landing gear mounting clamps as shown.

3. Reinstall the landing gear cover and tighten the fuselage screw (2mm x 15mm).

4. Install the nose wheel, aligning the ﬂat area on the nose gear with the set screw in the nose gear bracket.

TIP: The steering arm for the water rudder can be removed when ﬂying with

wheeled landing gear if desired.

5. Tighten the set screw.

TIP: Apply a drop of CA to the landing gear strut covers and nose gear set screw, if desired.

9 Make sure linkages move freely. 10 Test the ﬂap operation. 11 Perform the Control Direction Test with the transmitter. 12 Perform the AS3X Control Direction Test with the aircraft. 13 Adjust ﬂight controls and transmitter. 14 Perform a radio system Range Test. 15 Find a safe open area to ﬂy. 16 Plan ﬂight for ﬂying ﬁeld conditions.

Horizontal Tail Installation

1. Slide the horizontal stabilizer into place within the vertical ﬁn, inserting it with the elevator control horn on the bottom of the stabilizer and the right side of the fuselage.

2. Install two screws (2mm x 10mm) on each side of the horizontal tail, as shown.

3. Move the elevator up and down several times. If the elevator joiner binds against the fuselage, continue to ﬂex it until the binding is eliminated to allow for proper movement.

TIP: Check and tighten any screws securing the control horns as needed. Do not overtighten the screws as it could damage the control surface and/or control horn.

4. Snap the elevator clevis into place, then snap the rudder clevis into place, if needed.

5. Slide the horizontal stabilizing ﬁns into place.

TIP: You may apply a drop of CA to secure the horizontal stabilizing ﬁns, if desired.

Wing Installation

1. Connect the ESC, ailerons, LED lights, and ﬂaps to the receiver in the following locations: 1–ESC 2–Aileron 3–Elevator 4–Rudder 5–LED Lights 6–Flaps

2. Install the wing, then secure it by tightening the thumb screw as shown.

3. Slide each wing strut into the fuselage slot.

4. Snap each wing strut into place at rear of motor nacelle.

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. Determine which propeller matches each image and install as shown.

2. Install the left propeller (T7056C) on the left propeller adaptor. Install the right propeller (T7056CR) on the right propeller adaptor. Tighten each nut to secure each propeller in place. The nut securing the T7056CR propeller on the right wing is reverse threaded.

3. Install the spinners and secure them in place with a 2mm x 10mm machine screw.

Receiver Installation (PNP)

The Spektrum AR631 receiver is recommended for this airplane. If you choose to install another receiver, ensure that it is at least a 5-channel full range (sport) receiver. Refer to your receiver manual for correct installation and operation instructions.

Installation (AR631 shown)

1. Mount the receiver parallel to the length of the fuselage as shown. Use double-sided servo tape.

CAUTION: Incorrect installation of the receiver could cause a crash.

2. Attach the appropriate control surfaces to the their respective ports on the receiver using the chart in the illustration.

IMPORTANT: After you set up your model, always rebind the transmitter and

receiver to set the desired failsafe positions. If you are using a 6 channel transmitter, the FLAP Channel (CH 6) controls the ﬂaps.

Dual Rates

Attempt your ﬁrst ﬂights in Low Rate. For landings, use high rate elevator.

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 ﬁrst ﬂights, you may adjust expo in your transmitter.

†

Some of the terminology and function locations used in the iX12 and iX20 programming may be slightly different than other Spektrum AirWare™ radios. The names given in parenthesis correspond to the iX programming terminology. Consult your transmitter manual for speciﬁc information about programming your transmitter.

* Flap programming values may vary slightly. For your initial ﬂights use the

recommended ﬂap travel settings provided in the Flaps section and adjust the ﬂap travel to your preference on subsequent ﬂights.

Computerized Transmitter Setup

Start all transmitter programming with a blank ACRO model (perform a model reset), then name the model.
