Required Tools

Low Voltage Cutoff (LVC)

• When a Li-Po battery is discharged below 3V per cell, it will not hold a charge. The aircraft’s ESC protects the flight battery from over-discharge using Low Voltage Cutoff (LVC). Once the battery discharges to 3V per cell, the LVC will reduce the power to the motor to leave adequate power to the receiver and servos to land the airplane.
• When the motor power decreases, land the aircraft immediately and replace or recharge the flight battery.
• Always disconnect and remove the Li-Po battery from the aircraft after each flight. Charge your Li-Po battery to about half capacity before storage. Make sure the battery charge does not fall below 3V per cell. Failure to unplug a connected battery will result in trickle discharge.

NOTICE: Repeated flying to LVC will damage the battery.

Transmitter Setup

Transmitter Setup (BNF Basic)

• 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, and CG range is 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 the throttle cut before approaching the aircraft.

Dual Rates
A 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 the first flights, you may adjust exponentially in your transmitter.

Transmitter Telemetry Setup
If the transmitter that you intend to use with this aircraft is not displaying telemetry data, visit Spektrumrc.com and update your firmware. With the latest firmware installed on your transmitter, the telemetry option should now be functional on your transmitter.

1. Insert the main landing gear wires into the landing gear mounting brackets on the bottom of the wings.
2. Secure the main gear in place with the retainers and the M2.5 x 16mm screws, as shown.

Wing Installation

IMPORTANT:
Hands-free servo connectors are installed in the wing and fuselage mating surfaces. Ensure that they slide together correctly.

1. Slide the wing tube into the fuselage.
2. Slide the wings onto the wing tube until they fully seat to the fuselage.
3. Secure the wing halves in position using the included M3 x 8mm screws. Disassemble in reverse order.

Antenna Installation

1. Place the dummy antenna on the front of the hatch latch.
2. Secure the dummy antenna into place with the included M2 x 5mm screw, as shown.

Propeller Installation

1. Install the propeller adapter, propeller, propeller washer, and nut.
2. Tighten the nut until the prop adapter grasps the propeller shaft securely.
3. Secure the spinner with a M3 x 8mm screw. Disassemble in reverse order.

Control Surface Centering

After assembly and transmitter setup, confirm that the control surfaces are centered. The model must be powered on and bound to the transmitter, with the throttle at the lowest setting.

IMPORTANT: Control surface centering must be done with SAFE mode OFF.

1. Verify the trims and sub-trims on your transmitter are set to zero.
2. Power on the model with SAFE mode OFF and the throttle at the lowest setting.
3. If any of the control surfaces are not centered, loosen the screw in the quick connector linkage on the servo arm for the control surface that requires adjustment.
4. Slide the pushrod in or out through the quick connector to center the control surface.
5. Apply a small amount of removable thread lock compound to the screw threads.
6. Tighten the screw to secure the pushrod.

General Binding Tips and Failsafe

• 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. Fail-safe moves the throttle channel to the 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/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. 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 a 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.

To Disable SAFE Select

SAFE SELECT DISABLED:
The control surfaces cycle back and forth once every time the receiver is powered on.

Using The Bind Plug

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.

To Disable SAFE Select

SAFE SELECT DISABLED:
The control surfaces cycle back and forth once every time the receiver is powered on.

Battery Installation and ESC Arming

We recommend the Spektrum™ 14.8V 2200mAh 4S 30C Smart LiPo Battery: IC3 (SPMX22004S30). Refer to the Optional Accessories 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 your 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 to the lowest settings. Power on the transmitter.
2. Pull the hatch latch aft to release the hatch, and lift the hatch rear.
3. For added security, apply the loop side (soft side) of the optional hook and loop tape to the bottom of the battery and the hook side to the battery tray.
4. Install a fully charged battery in the middle of the battery compartment, as shown. Secure it using the hook and loop straps.
5. Connect the battery to the ESC. If you have not completed the bind sequence, do so at this time as outlined in this manual.
6. On a flat surface, keep the aircraft immobile, upright, and out of the wind, or the system will not initialize.
   • The motor emits a steady beep when the battery is connected, then 4 tones (indicating the number of connected cells) followed by a rising tone to indicate the ESC is armed.
   • An LED will light on the receiver when it is initialized.
7. Reinstall the battery hatch.

SAFE Select Technology

The E-flite Piper Cherokee has two flight modes controlled by Channel 5, SAFE and AS3X. Switch A is the Spektrum default for channel 5. Position 0 is SAFE, Position 1 is AS3X only. When flying in SAFE mode, the aircraft will return to level flight any time the aileron and elevator controls are at neutral. Applying an aileron or elevator control will cause the airplane to bank, climb, or dive. The amount the stick is moved will determine the attitude of the airplane flies. Holding full control will push the aircraft to the pre- determined bank and pitch limits, but it will not go past those angles.

When flying in SAFE mode, it is normal to hold the control stick deflected with moderate aileron input when flying through a turn. To fly smoothly with SAFE, avoid making frequent control changes and don’t attempt to correct for minor deviations. Holding deliberate control inputs will command the aircraft to fly at a specific angle, and the model will make all corrections to maintain that flight attitude. Return the elevator and aileron controls to neutral before switching from SAFE mode to AS3X mode. If you do not neutralize controls when switching into AS3X mode, the control inputs used for SAFE mode will be excessive for AS3X mode and the aircraft will react immediately.

Differences Between SAFE and AS3X Modes
This section is generally accurate but does not take into account flight speed, battery charge status, and other limiting factors.

slowly
Holding full control| Aircraft will bank or pitch to the predetermined limits and maintain the attitude| Aircraft will continue to roll or pitch rapidly

Disabling and Enabling SAFE Select
By default, the SAFE Select function of your aircraft is enabled and assigned to the gear channel switch (channel 5). If you do not wish to have access to SAFE Select while flying, you can choose to disable the SAFE Select functionality. AS3X will still be active when SAFE Select is disabled.

IMPORTANT:
Before attempting to disable or enable SAFE Select, ensure the aileron, elevator, rudder, throttle, and gear channels are all on high rate with the travel set to 100%. Turn the throttle hold OFF if it is programmed in the transmitter.

CAUTION:
Keep all body parts clear of the propeller, and keep the aircraft securely restrained in case of accidental throttle activation.

1. Power on the transmitter.
2. Power on the aircraft.
3. Hold both transmitter sticks to the inside bottom corners and toggle the Gear switch 5 times (1 toggle = full up and down). The control surfaces of the aircraft will move, indicating SAFE Select has been enabled or disabled.

Repeat the process to disable or enable or disable SAFE Select. The aircraft will cycle both ailerons up and down to indicate a change has been made.

DXe and DXS Transmitters
Switch A is the FMODE switch on these transmitters, and the switch needs to be toggled between positions 0 and 2 when disabling/enabling SAFE Select.

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 left aileron should move up and the right aileron down, 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.
   Elevator

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

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

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

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

AS3X Control Response Test (BNF Basic)
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.
   CAUTION: Keep all body parts, hair, and loose clothing away from a moving propeller, 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.

Center of Gravity (CG)
The CG location is measured from the leading edge of the wing at the root. This CG location has been determined with the recommended Li-Po battery (SPMX22004S30). Measure the CG with the aircraft inverted.

In Flight Trimming

• During your first flight, trim the aircraft for level flight at 3/4 throttle. 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 allows the receiver to learn the correct settings to optimize AS3X performance.
• Failure to do so could affect flight performance.

Flying Tips and Repairs

Consult local laws and ordinances before choosing a flying location.

• Flying Field
  Always choose a wide-open space for flying your aircraft. It is recommended that you fly at a designated RC flying field. Always avoid flying near houses, trees, wires, and buildings. Avoid flying in areas where there are many people, such as parks, schoolyards, or soccer fields.

• Range Check your Radio System
  Before you fly, range check the radio system. Refer to your specific transmitter instruction manual for range test information.

• Understanding 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 conditions, you will see oscillation. If oscillation occurs, decrease airspeed. If oscillation persists, refer to the Troubleshooting Guide for more information.

• Takeoff
  Place the aircraft in position for takeoff (facing into the wind). Set your transmitter at a low rate gradually increase the throttle from ¾ to full and steer with the rudder. As the airplane gains speed, gently pull back on the elevator and climb to a comfortable altitude. You may also set flaps to half- travel for shorter takeoffs.

• Flying
  Fly the airplane and trim it for level flight at ¾ throttle with flaps up. After adjusting the trim in flight do not touch the control sticks for 3 seconds. This allows the receiver to learn the correct settings to optimize AS3X performance.

• Landing
  TIP: To prevent damage to the landing gear wheel pants, remove them when landing the aircraft in tall grass.

Make sure to land the aircraft in the wind. Start to slow the model down to an approach speed and set the flaps to half travel. If landing in windy conditions, land at half-flap travel. If flying in light winds, set flaps to full for the final approach. With flaps and retracts extended, fly the aircraft to approximately 36 inches (90 cm) or less above the runway, using a small amount of throttle for the entire descent. 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.

• NOTICE: When using flaps with this airplane, down elevator to flap mixing is required. Failure to do so may result in loss of control or a crash.
• 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 and install the new receiver in the same orientation as the original receiver damage may result.
• NOTICE: Crash damage is not covered under warranty.
• NOTICE: When you are finished flying, never leave the airplane in direct sunlight or a hot, enclosed area such as a car. Doing so can damage the foam.

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 the power supplied to the motor. Power to the motor pulses, 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 Smart LiPo Battery Checker and Servo Driver (SPMXBC100, sold separately).

Repairs
Thanks to the EPO foam 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 The use accelerator on your aircraft can damage paint. The O NOT does handle the aircraft until the accelerator fully dries.

PNP Receiver Selection and Installation
The Spektrum AR631 receiver is recommended for this airplane. If you choose to install another receiver, ensure that it is at least a 6-channel full-range receiver. Refer to your receiver manual for correct installation and operation instructions.

Installation (AR631 shown)

1. Remove the hatch from the fuselage.
2. Mount the receiver parallel to the length of the fuselage as shown. Use double-sided servo tape.
3. Attach the appropriate control surfaces to their respective ports on the receiver using the chart in the illustration.

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

AMA National Model Aircraft Safety Code

Effective January 1, 2018
A model aircraft is a non-human-carrying device capable of sustained flight within the visual line of sight of the pilot or spotter(s). It may not exceed the limitations of this code and is intended exclusively for sport, recreation, education, and/or competition. All model flights must be conducted by this safety code and related AMA guidelines, any additional rules specific to the flying site, as well as all applicable laws and regulations.

As an AMA member, I agree:

• I will not fly a model aircraft carelessly or recklessly.

• I will not interfere with and will yield the right of way to all human-carrying aircraft using AMA’s See and Avoid Guidance and a spotter when appropriate.

• I will not operate any model aircraft while I am under the influence of alcohol or any drug that could adversely affect my ability to safely control the model.

• I will avoid flying directly over unprotected people, moving vehicles, and occupied structures.

• I will fly Free Flight (FF) and Control Line (CL) models in compliance with AMA’s safety programming.

• I will maintain visual contact with an RC model aircraft without enhancement other than the corrective lenses prescribed to me. When using an advanced flight system, such as an autopilot, or flying First-Person View (FPV),
  I will comply with AMA’s Advanced Flight System programming.

• I will only fly models weighing more than 55 pounds, including fuel if certified through AMA’s Large Model Airplane Program.

• I will only fly a turbine-powered model aircraft in compliance with AMA’s Gas Turbine Program.

• I will not fly a powered model outdoors closer than 25 feet to any individual, except for myself or my helper(s) located at the flight line, unless I am taking off and landing, or as otherwise provided in AMA’s Competition Regulation.

• I will use an established safety line to separate all model aircraft operations from spectators and bystanders.
