SAFE ® Select Technology

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, or it can be enabled via forwarding Programming. When the airplane is bound with SAFE Select enabled, a switch can be assigned to toggle SAFE Select ON or OFF. AS3X® technology remains active at all times.
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

Serious injury could result if the motor starts inadvertently with the propeller still attached.

Model Assembly

Horizontal Stabilizer Installation

1. Slide the horizontal stabilizer joiner into the hole in the rear of the fuselage.
2. Flex each of the elevators up and down several times to ensure the hinge allows the elevators to move freely.
3. Install the two-piece (left and right) horizontal stabilizer as shown. Ensure the control horn faces down.
4. Secure the horizontal stabilizer pieces in place using the two included 3 x 12 mm self-tapping screws (Pack C).

Wing Installation

1. Connect the Y harnesses as shown.
   Note: Verify polarity when connecting servo leads. The included Y-harnesses have
   a yellow signal wire which connects to the white wire on the servo lead.
   • Flaps: Y-harness (Pack A) connects the flap servo plugs in the center of the wing with the receiver.
   • Ailerons: Y-harness (Pack A) connects the aileron servo plugs in the center of the wing with the receiver.
   • Gear: There is a 3-way Y-harness connected to the receiver with 2 open plugs. The servo plugs from the retract mounted in the wing should be connected directly into the 3-way Y-harness in the receiver when installing the wing.

2. Locate the holes for the M3 x 20mm wing screws (Pack B) and begin to thread the screws into place.

3. Press the wing into place, being cautious to prevent pinching servo wires.

4. Tighten the wing screws.
   Servo connector locks
   The Y harnesses have a locking feature to secure the servo leads in place. Gently lift the locking tabs to remove the connector.

Receiver Selection and Installation PNP

The recommended receiver for this aircraft is the Spektrum AR631. If you choose to install a different receiver, ensure that it is at least a 6-channel full range receiver. Refer
to the manual of your chosen receiver for correct installation and operation instructions.
AR631 Installation

1. Connect the servos to their respective ports in the receiver using the table at the right.
2. Using high-quality double-sided servo tape (not included), mount the receiver to the flat 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.

NOTE: The rudder and nose gear servo has a Y-harness installed from the factory. The nose gear servo lead is labeled “Rudd”, indicating it is plugged into the rudder channel.
CAUTION: Incorrect installation of the receiver could cause a crash.
Antenna Installation
The AR631 receiver has a coaxial-style antenna. We recommend installing the antenna as far as possible from metal, batteries, or carbon fiber to maximize signal reception performance.
NOTICE: Do not cut, kink, or modify the antenna. Damage to the coaxial portion of an antenna will reduce its performance of the antenna. Shortening or cutting off the 31mm tip will reduce the range.

Connect the Pushrods to the Control Surfaces

Control Horn and Servo Arm Settings
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 AR631 gain values may need to be adjusted. Refer to the Spektrum AR631 manual for adjustment of gain values. After flying, you may choose to adjust the linkage positions for the desired control response. See the table to the right.

General Binding Tips and Failsafe BNF

• The included receiver has been specifically programmed for the 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.

**Transmitter and Receiver Binding / Enabling and Disabling SAFE Select

BNF**

The BNF Basic version of this airplane includes SAFE Select technology, enabling you to choose the level of flight protection. The 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 binding 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 the conventional bind plug to complete the binding and SAFE Select process.
Using The Bind Button…
To Enable SAFE Select

SAFE SELECT ENABLED: The control surfaces cycle back and forth twice with a slight pause at a neutral position every time the receiver is powered on.

SAFE ® Select Switch Designation BNF

Once SAFE Select is enabled, you can choose to fly in SAFE mode full-time or assign a switch. Any switch on any channel between 5 and 9 can be used on your transmitter.
If the aircraft is bound with SAFE Select disabled, the aircraft will be in AS3X mode exclusively.
CAUTION: Keep all body parts well clear of the propeller and keep the aircraft securely restrained in case of accidental throttle activation.
IMPORTANT: To be able to assign a switch, first verify:

• The aircraft was bound with SAFE Select enabled.
• Your choice for the SAFE Select switch is assigned to a channel between 5 and 9 (Gear, Aux1-4), and travel is set at 100% in each direction.
• The aileron, elevator, rudder and throttle direction are set to normal, not reverse.
• The aileron, elevator, rudder and throttle are set to 100% travel. If dual rates are in use, the switches need to be in the 100% position.
  See your transmitter manual for more information about assigning a switch to a channel.

Assigning a Switch with Stick Inputs

1. Power on the transmitter.
2. Power on the aircraft.
3.  Hold both transmitter’s sticks to the inside bottom corners, and toggle the desired switch 5 times quickly (1 toggle = full up and down).* This example of the channel monitor shows the stick positions for assigning a switch, the switch selection on Aux2, and +/- 100% travel on the switch.
4. The control surfaces of the aircraft will move, indicating the switch has been selected.
   Repeat the process to assign a different switch or to deactivate the current switch.

Battery Installation and ESC Arming

The Spektrum ™ Smart 2200mAh 4S 30C Li-Po battery (SPMX22004S30) is recommended for best performance.
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 Li-Po battery pack to fit in the fuselage. Be sure the model balances at the recommended CG before flying.
WARNING: Always keep hands away from the propeller. When armed, the motor will turn the propeller in response to any throttle movement. If your transmitter supports it, always engage a throttle cut before approaching the aircraft any time a battery is connected.

1. Lower the throttle and throttle trim to the lowest settings. Power on the transmitter then waits 5 seconds.

2. Push back on the hatch release button behind the canopy and lift up on the rear of the hatch up to remove the hatch from the fuselage.

3. Install the fully charged battery in the middle of the battery compartment, as shown. Secure using the three included hook and loop straps.

4. Connect the battery to the ESC (the ESC is now armed).

5. Keep the aircraft immobile and away from wind or the system will not initialize.
   • The ESC will sound a series of tones.
   • An LED will light on the receiver.
   • If the ESC sounds a continuous double beep after the flight battery is connected, recharge or replaces the battery.

6. Push back on the hatch release button before pressing down on the canopy to reinstall the canopy hatch.
   IMPORTANT: The hatch release button will not engage by pressing down on the canopy. You must move the hatch release button back while lowering the canopy in
   order for it to engage.

Control Surface Direction

Switch on the transmitter and connect the battery. Use the transmitter to operate the aileron, elevator, and rudder controls. View the aircraft from the rear when checking the control directions.
Ailerons

1. Move the aileron stick to the left. The right aileron should move down and the left aileron up, which will cause the aircraft to bank left.

2. Move the aileron stick to the right. The right aileron should move up and the left aileron down, which will cause the aircraft to bank right.
   Elevators

3. Pull the elevator stick back. The elevator should move up, which will cause the aircraft to pitch up.

4. Push the elevator stick forward. The elevator should move down, which will cause the aircraft to pitch down.
   Rudder

5. Move the rudder stick to the left. The rudder should move to the left, which will cause the aircraft to yaw left.

6. Move the rudder stick to the right. The rudder should move to the right, which will cause the aircraft to yaw right.

AS3X ® Control Response Test

WARNING: Do not perform any testing or maintenance with the propeller installed on the aircraft. Serious injury or property damage could result from the motor starting inadvertently.
This test ensures that the AS3X control system is functioning properly. Assemble the aircraft and bind your transmitter to the receiver before performing this test.

1. Raise the throttle just above 25%, then lower the throttle to activate AS3X technology.
   WARNING: Keep all body parts, hair and loose clothing away from the spinning motor, as these items could become entangled.

2. Move the entire aircraft as shown and ensure the control surfaces move in the direction indicated in the graphic. If the control surfaces do not respond as shown, do not fly the aircraft. Refer to the receiver manual for more information. Once the AS3X system is active, control surfaces may move rapidly. This is normal. AS3X remains active until the battery is disconnected.

Control Surface Centering
After assembly and transmitter setup, confirm that the control surfaces are centered. The model must be powered, bound to the transmitter in AS3X mode, with the throttle left at zero. When enabled, SAFE mode is active at power up. AS3X mode is activated when the throttle is raised above 25% for the first time after being powered on. It is normal for the control surfaces to respond to aircraft movement if the aircraft is in AS3X or SAFE modes.

1. Verify the trims and sub-trims on your transmitter are zero
2. Power up the model in AS3X mode and leave the throttle at zero
3. Look at the tip of each control surface and verify it is mechanically centered.
4. If adjustment is required, turn the clevis on the linkage to change the length of the linkage between the servo arm and the control horn.

Dual Rates and Control Throws
Program your transmitter to set the rates and control throws to the values given.
These values have been tested and are a good starting point to achieving a successful flight.
After flying, you may choose to adjust the values for the desired control response.

| High Rate| Low Rate
---|---|---
Aileron| ▲ = 16mm

▼ = 16mm

| ▲ = 9mm

▼ = 9mm

Elevator| ▲ = 15mm

▼ = 10mm

| ▲ = 10mm

▼ = 8mm

Rudder| ▶ = 20mm

◀ = 20mm

| ▶ = 13mm

◀ = 13mm

Propeller Installation

WARNING: Do not install the propeller until the aircraft has been completely assembled, all the systems have been checked thoroughly and you are located at a suitable flying site.
WARNING: Never install a cracked, nicked or otherwise damaged propeller.
NOTICE: If the propeller is not balanced, the aircraft may vibrate, causing the stabilization system to not operate correctly and/or decrease the life of the servos.

1. Install the propeller, ensuring the embossed size numbers are facing forward.
2. Install the prop nut. Do not over-tighten the prop nut as damage to the propeller or threads may result.

Center of Gravity (CG)

The CG location is measured along the mold line on the bottom of the wing. The recommended starting location is 83mm back from the front of the wing saddle. This CG location has been determined with the recommended Li-Po battery (SPMX22004S30).
WARNING: Install the battery but do not arm the ESC while checking the CG. Personal injury may result.
TIP: Measure the CG with the aircraft inverted.

Flying Tips and Repairs

Consult local laws and ordinances before choosing a flying location.
Range Check your Radio System
Before you fly, range check the radio system. Refer to your specific transmitter instruction manual for range test information.
Oscillation
Once the AS3X system is active (after advancing the throttle for the first time), you will normally see the control surfaces react to aircraft movement. In some flight condi,tions
you may see oscillation (the aircraft rocks back and forth on one axis due to overcontrol). If oscillation occurs, refer to the Troubleshooting Guide for more information.
Takeoff
Place the aircraft facing into the wind. Set your transmitter in low rate and use your flaps switch to drop the flaps to takeoff or “half position”. Gradually increase the throttle to ¾ and steer with the rudder. Flaps make takeoffs shorter. As the tail comes off the ground, pull back gently on the elevator. When airborne, flip your gear switch to raise your landing gear. Climb to a comfortable altitude and then flip your flaps switch to level the flaps.
Flying
For your first flights with the recommended battery pack (SPMX22004S30), set your transmitter timer or a stopwatch to 4 minutes, land the aircraft. Adjust your timer for longer or shorter flights once you have flown the model. If at any time the motor power reduces, land the aircraft immediately to recharge the flight battery. See the Low Voltage Cutoff (LVC) section for more details on maximizing battery health and run time.
Landing
Land the aircraft into the wind. Use high-rate Elevators for landings. Use a small amount of throttle for the entire descent. Lower the throttle to ¼ and select your flap to switch to deploy the flaps to the landing, or full down position. Flaps will make the landing approach steeper and slower, and allow for a smoother landing. Flip your gear switch to lower your landing gear. This will slow the aircraft further. Keep the throttle on until the aircraft is ready to flare. During a flare, keep the wings level and the aircraft pointed into the wind. Gently lower the throttle while pulling back on the elevator to bring the aircraft down on its wheels.
If landing on grass, it is best to hold the full up elevator after touchdown and when taxiing to prevent nosing over.
Once on the ground, avoid sharp turns until the plane has slowed enough to prevent scraping the wingtips.
NOTICE: If a crash is imminent, reduce the throttle and trim fully. Failure to do so could result in extra damage to the airframe, as well as damage to the ESC and motor.
NOTICE: After any impact, always ensure the receiver is secure in the fuselage. If you replace the receiver, install the new receiver in the same orientation as the original receiver or damage may result.
NOTICE: Crash damage is not covered under warranty.
NOTICE: When you are finished flying, never leave the aircraft in direct sunlight or in a hot, enclosed area such as a car. Doing so can damage the aircraft.
Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per cell, it will not hold a charge. The ESC protects the flight battery from over-discharge using Low Voltage Cutoff (LVC).
Before the battery charge decreases too much, LVC removes power supplied to the motor. Power to the motor reduces, showing that some battery power is reserved for flight control and safe landing.
Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle discharge. Charge your Li-Po battery to about half capacity before storage.
During storage, make sure the battery charge does not fall below 3V per cell. LVC
does not prevent the battery from over-discharge during storage.
NOTICE: Repeated flying to LVC will damage the battery.
TIP: Monitor your aircraft battery’s voltage before and after flying by using a Li-Po Cell Voltage Checker (SPMXBC100, sold separately).
Repairs
Thanks to the EPO material in this aircraft, repairs to the foam can be made using virtually any adhesive (hot glue, regular CA, epoxy, etc). When parts are not repairable, see the Replacement Parts List for ordering by item number. For a listing of all replacement and optional parts, refer to the list at the end of this manual.
NOTICE: Use of CA accelerant on your aircraft can damage paint. DO NOT handle the aircraft until the accelerant fully dries.

In Flight Trimming
During your first flight, trim the aircraft for level flight at 3/4 throttle with flaps up. Make small trim adjustments with your transmitter’s trim switches to straighten the
aircraft’s flight path.
After adjusting the trim, do not touch the control sticks for 3 seconds. This allow the receiver to learn the correct settings to optimize AS3X performance.
Failure to do so could affect flight performance.

Post Flight

1. Disconnect the flight battery from the ESC (Required for safety and battery life).
2. Power OFF the transmitter.
3. Remove the flight battery from the aircraft.
4. Recharge the flight battery.
5. Repair or replace all damaged parts.
6. Store the flight battery apart from the aircraft and monitor the battery charge.
7. Make note of the flight conditions and flight plan results, planning for future flights.

Motor Service

CAUTION: Always disconnect the flight battery before performing motor service.
Disassembly

1. Remove the spinner nut by using a small screwdriver or hex wrench.
2. Remove the propeller.
3. Remove the four screws from the front of the cowling and remove the dummy radial engine from the fuselage.
