SAFE Select Technology BNF

The BNF Basic version of this aircraft features SAFE Select technology for enhanced in-flight protection. SAFE Select prevents the aircraft from exceeding pre-set limits or tipping. Automatic self-leveling keeps the aircraft in a straight and level flight attitude when control surfaces are neutral. SAFE Select is activated or deactivated during the binding process. If SAFE Select is activated, a switch can be assigned to toggle between SAFE Select mode and AS3X mode. AS3X technology remains active without bank limits or self-leveling when SAFE Select is deactivated.

SAFE Select can be configured in three ways:

• SAFE Select Off: Always in AS3X mode.
• SAFE Select On - No Switch Assigned: Always in SAFE Select mode.
• SAFE Select On with Assigned Switch: Toggle between SAFE Select and AS3X modes.

PNP Receiver Selection and Installation

The recommended receiver for this aircraft is the Spektrum AR631. If installing a different receiver, it must be at least a full (sport) receiver with 4 channels. Refer to the manual of your chosen receiver for correct installation and operation.

AR631 Installation

1. Lift the rear part of the canopy to remove it.
2. Connect the respective control surfaces to their corresponding ports on the receiver as shown in the table on the right.
3. Secure the receiver with double-sided servo tape in the flat area behind the ESC as shown. The receiver should be mounted parallel to the fuselage length in the orientation shown, with the label facing down and the servo connectors facing the rear of the aircraft. The receiver's orientation is absolutely critical for the technical configuration of all AS3X® and SAFE® systems.

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

Antenna Installation

The AR8360T receiver has coaxial antennas. It is recommended to mount the antennas at a 90° angle to each other and as far as possible from metal, batteries, carbon fiber, or fuel tanks to maximize signal reception.

NOTICE: Do not cut, kink, or modify the antennas. Damage to the coaxial area of the antenna will reduce its performance. Shortening or cutting off the tip by 31 mm will reduce the range.

Receiver Port Assignments: 1 = Throttle, 2 = Aileron, 3 = Elevator, 4 = Rudder.

Active part of the antenna is indicated.

Installing the Battery and Arming the ESC

Battery Selection

The recommended battery is the Spektrum 2200mAh 14.8V 4S 30C Li-Po battery (SPMX22004S30). Please refer to the optional accessories list for other batteries. If using a different battery not listed, it must match the E-flite battery in weight, capacity, and dimensions to fit in the fuselage. Ensure the battery achieves the recommended Center of Gravity (CG).

1. Move the throttle and throttle trim all the way down. Turn on the transmitter and wait 5 seconds.
2. Attach the hook-and-loop side of the hook-and-loop tape (A) to the underside of the battery.
3. Gently lift the rear edge of the canopy to remove it.
4. Insert a fully charged battery (C) into the battery compartment. Refer to the "Setting the Center of Gravity" section for more information.
5. Connect the battery to the ESC. The ESC is now armed.
• The ESC will produce a series of tones.
• An LED will light up on the receiver.

If the ESC emits a continuous double beep after connecting the battery, charge or replace the battery.

6. Replace the canopy.

CAUTION: Keep your hands well clear of the propeller at all times. When armed, the motor will spin the propeller with any movement of the throttle stick.

Center of Gravity (CG)

WARNING: Install batteries, but do not connect them to the ESC while checking the CG. This can cause injury. Place the battery as far forward as possible in the battery holder and secure it with hook-and-loop tape. The easiest way to determine the center of gravity is to turn the aircraft upside down.

CG is measured 67-72mm back from the leading edge of the wing at the root.

Failsafe and General Tips for Binding BNF

General Binding Tips

• The included receiver is specifically programmed for the operation of this aircraft. After replacing the receiver, refer to the receiver manual for proper setup instructions.
• Keep away from large metal objects during binding.
• Do not point the transmitter antenna directly at the receiver during binding.
• The orange LED on the receiver will begin to blink rapidly when the receiver enters bind mode.
• After successful binding, the receiver retains its binding settings until a new binding occurs.
• If communication between the receiver and transmitter is interrupted, failsafe is activated. Failsafe will move the throttle channel to the "low throttle" position. The elevator and aileron channels will move to actively stabilize the aircraft in a bank or turn.
• If problems occur, consult the troubleshooting guide, and if necessary, contact Horizon Product Support.

Binding Transmitter and Receiver / Enabling and Disabling SAFE Select BNF

The BNF Basic version of this aircraft is equipped with SAFE Select technology, which allows you to select the degree of flight protection. SAFE mode includes bank angle and automatic self-leveling limits. AS3X mode allows the pilot direct response to the control sticks. SAFE Select is activated or deactivated during the binding process.

If SAFE Select is deactivated, the aircraft will always be in AS3X mode. If SAFE Select is activated, the aircraft will always be in SAFE Select mode. Alternatively, a switch can be assigned to toggle between SAFE Select and AS3X modes.

Thanks to SAFE Select technology, this aircraft can be configured for full-time SAFE mode or full-time AS3X mode. Mode selection can also be assigned to a switch.

IMPORTANT: Before binding, read the transmitter setup section of this manual and complete the transmitter setup to ensure the transmitter is programmed correctly for this aircraft.

IMPORTANT: Set the transmitter's flight controls (elevator, aileron, and rudder) and throttle trim to neutral. Set the throttle to low before and during binding. This process defines the failsafe settings.

To complete binding and the SAFE Select process, you can use either the binding switch on the receiver case or the conventional bind plug.

Using the Binding Switch

SAFE Select Enabled: Lower throttle, apply power, press and hold the bind switch, release bind switch, bind TX to RX. The LED will blink orange. The aircraft's control surfaces will move back and forth twice with a short pause at the neutral position when the receiver is powered on.

Using the Bind Plug

SAFE Select Enabled: Lower throttle, apply power, install bind plug, release bind switch, bind TX to RX. The LED will blink orange. The aircraft's control surfaces will move back and forth twice with a short pause at the neutral position when the receiver is powered on.

SAFE Select Disabled: Lower throttle, apply power, install bind plug, release bind switch, bind TX to RX. The LED will blink orange. The aircraft's control surfaces will move back and forth once when the receiver is powered on.

SAFE Select Switch Designation BNF

SAFE Select technology can be assigned to any open switch (2 or 3 position) that controls a channel (5-9) on the transmitter. Once assigned to a switch, SAFE Select provides the flexibility to choose between SAFE technology or AS3X mode during flight. If the aircraft was bound with SAFE Select turned off, it will remain exclusively in AS3X mode.

IMPORTANT: Before assigning the desired switch, ensure that the travel for that channel is set to 100% in both directions, and that the aileron, elevator, rudder, and throttle are all set to high rates with 100% travel.

CAUTION: Keep all body parts away from the propeller and hold the aircraft securely if the throttle is accidentally applied.

TIP: SAFE Select can be assigned to any unused channel 5-9. Refer to your transmitter's manual for more information on assigning a switch to a channel.

TIP: Use the channel monitor to confirm that the four main channels have 100% travel when assigning the switch.

TIP: Use the channel monitor to ensure that the switch intended for SAFE Select is active and moves a channel between 5-9, traveling 100% in each direction.

TIP: Ensure the four main channels are not reversed if you encounter problems assigning a SAFE Select switch.

Assigning a Switch

1. Bind the aircraft with SAFE Select enabled. This allows the system to be assigned to a switch.
2. Hold both transmitter sticks in the lower inner corners and toggle the desired switch 5 times (1 toggle = fully from top to bottom) to assign it. The aircraft's control surfaces will move to indicate that the switch has been selected.

If desired, repeat the process to assign a different switch or to disable the current switch.

Integrated ESC Telemetry

This aircraft is equipped with telemetry between the ESC and receiver, which can provide information such as battery voltage and temperature.

To View Telemetry:

1. Start with the transmitter bound to the receiver.
2. Turn on the transmitter.
3. Turn on the aircraft.
4. A signal bar will appear in the top left corner of the screen when telemetry information is being received.
5. The technology screens will appear when navigating past the servo monitor.

For more information on compatible transmitters, firmware updates, and transmitter telemetry technology, visit www.SpektrumRC.com.

Centering Control Surfaces

After assembling and setting up the transmitter, check that the control surfaces are centered. The model must be connected to the transmitter in AS3X mode with the throttle at zero. If enabled, SAFE mode is active upon power-up. AS3X mode is activated once the throttle is increased above 25% for the first time after power-up. It is normal for control surfaces to react to flight movements when the aircraft is in AS3X or SAFE mode.

1. Check that the trims and sub-trims on your transmitter are set to zero.
2. Turn on the model in AS3X mode and keep the throttle at zero.
3. Observe the tip of each control surface and ensure it is mechanically centered.
4. If adjustment is needed, rotate the linkage ball on the pushrod to change the length of the linkage between the servo arm and the control horn.

Diagrams show 90° alignment for control surfaces.

Control Direction Tests

Turn on the transmitter and connect the battery. Use the transmitter to control the aileron and elevator controls. When checking control directions, view the aircraft from behind.

Ailerons

1. Move the aileron stick left. The right aileron should move down and the left aileron should move up, causing the aircraft to bank left.
2. Move the aileron stick right. The right aileron should move up and the left aileron should move down, causing the aircraft to bank right.

Elevator

1. Pull the elevator stick back. The elevators should move up, causing the aircraft to climb.
2. Push the elevator stick forward. The elevators should move down, causing the aircraft to descend.

Rudder

1. Move the rudder stick left. The rudder should move left.
2. Move the rudder stick right. The rudder should move right.

Horn and Servo Arm Settings

The table on the right shows the factory settings for the control horns and servo arms. Fly the aircraft at the factory settings before making any changes.

NOTICE: If the factory settings for control throws are changed, the AR631 gain values may need to be adjusted. Refer to the Spektrum AR631 manual for adjusting gain values.

After flying, the linkage positions can be adjusted for desired control response. Refer to the following table.

AS3X Control Link Test BNF

This test ensures that the AS3X® control system is functioning correctly. Assemble the aircraft and bind the transmitter to the receiver before performing this test.

1. Lift the throttle stick slightly above 25%, then lower the throttle stick to activate the AS3X technology.

CAUTION: Keep all body parts, hair, and loose clothing away from the spinning propeller, as they can get caught in the propeller.

2. Move the entire aircraft as shown in the illustration and ensure that the control surfaces move in the directions indicated in the graphic. If the control surfaces do not react as shown, do not fly the aircraft. Refer to the receiver manual for more information.

The control surfaces may move rapidly once the AS3X system is active. This is normal. AS3X remains active until the battery is disconnected.

Trimming During Flight BNF

For the first flight, trim the aircraft for level flight with the throttle at 1/2. Make small trim adjustments with the transmitter's trim switches to improve the aircraft's straight-line flight. After setting the trims, do not touch the control sticks for 3 seconds. This allows the receiver to gather information for optimizing AS3X performance. Failure to do so may affect flight performance.

A 3-second delay is indicated.

Dual Rates and Control Throw

Program the transmitter to set speeds and control throws according to your experience level. These values have been tested and are a good starting point for a successful first flight.

After flying, the values can be adjusted for desired control response.

Flight Tips and Repairs

Please observe local regulations and laws before selecting an area to fly.

The Airfield

Always choose a wide, open field for flying. It is recommended to fly at an approved model airfield. Avoid flying near houses, trees, power lines, or buildings. Do not fly in crowded places such as parks, sports fields, or schoolyards.

Range Check Your Transmitter

Before flying, perform a range check with your transmitter. Refer to your transmitter's manual for instructions.

Takeoff

For the first flights, set the timer/stopwatch to 7 minutes. After the first flight, adjust the timer shorter or longer as desired. Position the aircraft for takeoff facing into the wind. Use low RPM for the first takeoff, then gradually increase throttle to 3/4 to full, steering with the rudder. Slowly pull back on the elevator to climb to an appropriate altitude.

Flying

Fly the aircraft with the throttle set to 3/4 for level flight. After landing, mechanically adjust the linkages to correct trim changes and then reset the trims to neutral. Ensure the aircraft flies straight and aligns itself without trim or sub-trim.

Landing

To land the T-28, fly the aircraft to approximately 30 cm above the ground. Reduce throttle to idle and increase elevator during the glide. Touch down with the main landing gear first, keeping the nose gear gently in the air. Do not apply too much elevator, or the aircraft will take off again. Use the rudder to maintain direction until the aircraft slows down. Avoid sharp turns on the ground, as the aircraft may scrape the ground with its wingtips.

WARNING: Immediately cut throttle if the propeller touches the ground.

NOTICE: If a crash is imminent, reduce throttle and trim completely. Failure to do so could result in additional damage to the fuselage, ESC, and motor.

NOTICE: After every impact, check that the receiver is still securely seated in the fuselage. When replacing the receiver, ensure it is installed in the same orientation and position as the old receiver, otherwise damage is likely.

NOTICE: Crash damage is not covered by the warranty.

NOTICE: Never leave the aircraft in the sun after flying. Do not store it in a hot, enclosed environment like a car. This could damage the foam.

Low Voltage Cutoff (LVC)

If a Li-Po battery is discharged below 3V per cell, it will no longer hold a charge. The ESC protects the flight battery from deep discharge with Low Voltage Cutoff (LVC). Before the battery voltage drops too low, the LVC cuts off the power supply to the motor. The power supply to the motor will stutter, indicating that some battery power is reserved for flight control and a safe landing.

Remove the Li-Po battery from the aircraft after use to prevent gradual discharge. Charge your Li-Po battery to approximately half capacity before storage. During storage, ensure the battery voltage does not drop below 3V per cell.

NOTICE: Repeatedly flying into Low Voltage Cutoff will damage the battery.

TIP: Check battery voltage before and after flying with a LiPo Volt Checker (SPMXBC100, sold separately).

Repairs

Thanks to the EPO foam material in this aircraft, foam repairs can be made with almost any adhesive (hot glue, regular CA, epoxy, etc.). The elevator is not made of this material; use only foam-compatible CA glue there.

If parts are irreparable, refer to the spare parts list for the part number.

NOTICE: Using activator spray for cyanoacrylate (CA) glue can damage the aircraft's paint. Do not handle the model until the activator is completely dry.

Post-Flight Checklist

1. Disconnect the flight battery from the ESC (necessary for safety and battery longevity).
2. Turn off the transmitter.
3. Remove the flight battery from the aircraft.
4. Recharge the flight battery.
5. Repair or replace damaged components.
6. Store the flight battery separately from the aircraft and monitor its charge.
7. Record flight conditions.

Flying with SAFE® Select BNF

When flying in SAFE Select mode, the aircraft will return to level flight when the aileron and elevator controls are neutral. Using the aileron or elevator control can cause the aircraft to bank, climb, or dive. The intensity with which the stick is moved determines the aircraft's attitude. Maintaining full control challenges the aircraft's preset bank and roll limits but does not exceed them.

When flying with SAFE Select, the control stick is typically held in a deflected position, with moderate input for turns. To fly smoothly with SAFE Select, avoid frequent control changes and minimize correcting minor deviations. Thoughtful control inputs command the aircraft to fly at a specific angle, and the model makes all adjustments to maintain that attitude.

When flying with SAFE Select, the throttle controls the aircraft's ascent or descent. Full throttle causes the aircraft to slightly nose up and climb. Mid-throttle maintains the aircraft's altitude. Low throttle causes the aircraft to slowly descend with the nose down.

Set the elevator and aileron controls to neutral, then switch from SAFE Select mode to AS3X mode. If the controls are not neutralized when switching to AS3X mode, the control inputs used for SAFE Select are too large for AS3X mode, and the aircraft will react immediately.

Differences Between SAFE Select and AS3X Modes

This section is generally accurate but does not account for flight speed, battery charge status, and other limiting factors.

Horizon is not responsible for direct or indirect consequential damages, loss of income, or commercial losses in any way related to the product, regardless of whether a claim is made in contract, warranty, or tort. Furthermore, Horizon will not accept any warranty claims that exceed the individual value of the product. Horizon has no control over the installation, use, or maintenance of the product or any product combinations chosen by the buyer. Horizon makes no warranty and accepts no claims for resulting injuries or damages. By using and installing the product, the buyer accepts all listed warranty terms without restriction or reservation.

If you, as the buyer, are not willing to accept these terms in connection with the use of the product, you are asked to return the product in unused condition in its original packaging to the seller.

Safety Information

This is a high-quality hobby product and not a toy. It must be used with caution and care and requires some mechanical and mental skills. Failure to operate the product safely and prudently can lead to injuries to living beings and significant property damage. This product is not intended for use by children without the supervision of a guardian. The manual contains safety instructions and regulations as well as tips for maintenance and operation of the product. It is essential to read and understand these instructions before initial commissioning. Only then can improper use be prevented and accidents with injuries and damage be avoided.

Questions, Help, and Repairs

Your local dealer and point of sale cannot carry out a warranty assessment without consulting Horizon. This also applies to warranty repairs. Therefore, in such cases, contact the dealer who will consult with Horizon to make a proper decision to help you as quickly as possible.

Maintenance and Repair

If your product needs to be serviced or repaired, contact either your dealer or Horizon directly.

Returns / Repairs will only be processed with an RMA number issued by Horizon. You or your dealer will receive this number from technical service. More information can be found in the service portal at www.Horizonhobby.de or by calling Horizon's technical service.

Pack the product carefully. Note that the original carton is usually not sufficient to prevent damage during shipping. Use a parcel service provider with a tracking function and insurance, as Horizon is not responsible for shipping until acceptance. Please include proof of purchase, a detailed description of the defect, and a list of all returned components. We also need your complete address, a phone number for inquiries, and an email address.

Warranty and Repairs

Warranty requests will only be processed if an original proof of purchase from an authorized dealer is provided, showing the buyer and purchase date. If a warranty case is confirmed, the product will be repaired or replaced. This decision rests solely with Horizon Hobby.

Paid Repairs

For paid repairs, we will provide a cost estimate to your dealer. The repair will only be carried out once we receive approval from the dealer. The repair cost is to be paid to your dealer. Paid repairs will incur a minimum of 30 minutes of workshop time and return shipping costs. If we do not receive your consent for repair within 90 days, we reserve the right to destroy or otherwise dispose of the product.

CAUTION: We only perform paid repairs for electronics and motors. Mechanical repairs, especially for helicopters and RC cars, are extremely complex and must therefore be carried out by the buyer themselves.
