Transmitter and Receiver Binding / Switching ON and OFF SAFE® Select
This product requires an approved Spektrum™ DSM2®/DSMX® compatible
transmitter. Visit www.bindnfly.com for a complete
list of approved transmitters.
The aircraft has an optional SAFE Select feature, which can be switched ON or
OFF easily by binding in a specific manner as described below.
IMPORTANT: Before binding a transmitter, read the Transmitter Setup
section of this manual to ensure that your transmitter is properly programmed
for this aircraft.
Bind Plug Installation
Switching ON SAFE Select Binding Sequence
Binding Procedure / Switching ON SAFE Select
IMPORTANT: The included AR631 receiver has been programmed for operation
specifically for this aircraft. Refer to the receiver manual for correct setup
if the receiver is replaced or is used in another aircraft.
CAUTION: When using a Futaba® transmitter with a Spektrum DSM® module,
you must reverse the throttle channel and rebind. Refer to your Spektrum
module manual for binding and failsafe instructions. Refer to your Futaba
transmitter manual for instructions on reversing the throttle channel. Move
the transmitter controls to neutral (flight controls: rudder, elevators, and
ailerons) or too low positions (throttle, throttle trim).*
Install a bind plug in the receiver bind port.
Place the aircraft level on its wheels, then connect the flight battery to the
ESC. The motor will produce a series of sounds. The orange bind LED on the
receiver will begin to flash rapidly.
Remove the bind plug from the bind port.
Take three steps away from the aircraft /receiver and then put the transmitter
in inbind mode. Refer to your transmitter’s manual for specific binding
instructions.
IMPORTANT: Do not point the transmitter’s antenna directly at the
receiver while binding.
IMPORTANT: Keep away from large metal objects while binding.
The receiver is bound to the transmitter when the orange bind light on the
receiver stays orange. The ESC will produce a series of sounds. The tones
indicate the ESC is armed, provided the throttle stick and throttle trim are
low enough to trigger arming.
IMPORTANT: Once bound, the receiver will retain its bind settings for
that transmitter until it has been intentionally changed, even when power is
cycled ON and OFF. Repeat the binding process as necessary.
SAFE Select ON Indication
Every time the receiver is powered ON the surfaces will cycle back and forth
twice with a slight pause at a neutral position to indicate that SAFE Select
is switched ON.
The throttle will not arm if the transmitter’s throttle control is not put at
the lowest position. If problems are encountered, follow the binding
instructions and refer to the transmitter troubleshooting guide for other
instructions. If needed, contact the appropriate Horizon Product Support
office.
Switching OFF SAFE Select Binding Sequence
Binding Procedure / Switching OFF SAFE Select
IMPORTANT: The included AR631 receiver has been programmed for operation
specifically for this aircraft. Refer to the receiver manual for correct setup
if the receiver is replaced or is used in another aircraft.
CAUTION: When using a Futaba® transmitter with a Spektrum DSM module, you
must reverse the throttle channel and rebind. Refer to your Spektrum module
manual for binding and failsafe instructions. Refer to your Futaba transmitter
manual for instructions on reversing the throttle channel.
Move the transmitter controls to neutral (flight controls: rudder, elevators,
and ailerons) or too low positions (throttle, throttle trim). *
Install a bind plug in the receiver bind port.
Place the aircraft level on its wheels, then connect the flight battery to the
ESC. The motor will produce a series of sounds.
The orange bind LED on the receiver will begin to flash rapidly. DO NOT
remove the bind plug at this time.
Take three steps away from the aircraft /receiver and then put the transmitter
in bind mode. Refer to your transmitter’s manual for specific binding
instructions.
IMPORTANT: Do not point the transmitter’s antenna directly at the
receiver while binding.
IMPORTANT: Keep away from large metal objects while binding.
The receiver is bound to the transmitter when the orange bind light on the
receiver stays orange. The ESC will produce a series of sounds. The tones
indicate the ESC is armed, provided the throttle stick and throttle trim are
low enough to trigger arming.
Remove the bind plug from the bind port.
IMPORTANT: Once bound, the receiver will retain its bind settings for
that transmitter until it has been intentionally changed, even when power is
cycled ON and OFF. Repeat the binding process as necessary.
SAFE Select OFF Indication
Every time the receiver is powered ON the surfaces will cycle back and forth
once to indicate that SAFE Select has been switched OFF.
The throttle will not arm if the transmitter’s throttle control is not put at
the lowest position. If problems are encountered, follow the binding
instructions and refer to the transmitter troubleshooting guide for other
instructions. If needed, contact the appropriate Horizon Product Support
office.
*Failsafe
If the receiver loses transmitter communication, the failsafe will activate.
When activated, failsafe move the throttle channel to its preset failsafe
position (low throttle) that was set during binding. All other channels move
to actively level the aircraft in flight.
SAFE® Select Switch Designation
SAFE® Select technology can be easily assigned to any open switch (two or
three positions) on the transmitter. With this new feature, you now have the
flexibility to enable or disable the technology while in flight.
IMPORTANT: Before assigning your desired switch, ensure that the travel
for that channel is set at 100% in both directions.
Assigning a switch
Bind the aircraft correctly to activate SAFE Select. This will allow the
system to be assigned to a switch.
Hold both transmitters sticks to the inside bottom corners and toggle the
desired switch five times (one toggle = full up and down) to assign that
switch. The control surfaces of the aircraft will move, indicating the switch
has been selected.
Repeat the process to deselect the switch or to assign a different switch if
desired.
TIP: SAFE Select is assignable on any unused Channels 5–9.
AS3X Control Direction Test
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.
-
Raise the throttle just above 25%, then lower the throttle to activate AS3X.
CAUTION: Keep all body parts, hair, and loose clothing away from a moving propeller, as these items could become entangled.
IMPORTANT: The AR631 programming for this aircraft increases control surface movement when flaps are fully down. -
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
(EFLB22003S30) installed to the front edge of the battery tray.
Tip: Measure the CG with the aircraft inverted.
NOTICE: Install the battery but do not arm the ESC while checking the CG.
Personal injury may result.
In-Flight Trimming
During your first flight, trim the aircraft for level flight at 3/4 throttle
with flaps and gear 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
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.
Range Check your Radio System
Before you fly, range checks 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 conditions, 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 at a 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 (EFLB22003S30), set
your transmitter timer or a stopwatch to 5 minutes. After five minutes, land
the aircraft. Adjust your timer for longer or shorter flights once you have
flown the model. If at any time the motor pulses, 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 Elevator for landings. Use a
small amount of throttle for the entire descent. Lower the throttle to ¼ and
flip your flaps 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 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.
WARNING: Always decrease throttle at propeller strike.
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 Li-Po Cell Voltage Checker (SPMXBC100, sold separately).
Repairs
Thanks to the Z-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 CA accelerant on your aircraft can damage the paint. DO
NOT handle the aircraft until the accelerant fully dries.

AMA National Model Aircraft Safety Code
Academy of Model Aeronautics
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
in accordance with 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 in a careless or reckless manner.
- 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 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.
