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 binding 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.
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 a switch assigned: Switch toggles between SAFE Select mode and AS3X mode

IMPORTANT: Do not point the transmitter’s antenna directly at the receiver while binding.
IMPORTANT: Keep away from large metal objects while binding.
6.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 slick and throttle trim are low enough to trigger aiming.
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 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 Futabe 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.
1.Move the transmitter controls to neutral (flight controls: rudder, elevators and ailerons) or to low positions (throttle, throttle trim). *
2.Install a bind plug In the receiver bind port.
3.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.
4.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.

6.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 moves 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 assigned to any open switch (2 or 3 position) controlling a channel (5–9) on your transmitter. Once assigned to a switch, SAFE select ON gives you the flexibility to choose SAFE technology or AS3X mode while in flight. If the aircraft is bound with SAFE select OFF, the aircraft will be in AS3X mode exclusively.
IMPORTANT: Before assigning your desired switch, ensure that the travel for that channel is set at 100% in both directions and the aileron, elevator, rudder and throttle are all on high rate with the travel at 100%.

CAUTION: Keep all body parts well clear of the propeller and keep the aircraft securely restrained in case of accidental throttle activation.
TIP: SAFE Select is assignable on any unused channels 5–9. See your transmitter manual for more information about assigning a switch to a channel.
TIP: Use your radio channel monitor to confirm that the four primary channels are showing 100% travel while assigning the switch.
TIP: Use the channel monitor to make sure the switch you are assigning for SAFE Select is active and driving a channel between 5-9 and that it is traveling 100% in each direction.
TIP: Make sure your four primary channels are not reversed if you are having trouble assigning a SAFE Select switch.

Assigning a switch

1. Bind the aircraft to choose SAFE Select ON. This will allow the system to be assigned to a switch.
2. Hold both transmitter sticks to the inside bottom corners and toggle the desired switch 5 times (1 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 assign a different switch or to deactivate the current switch if desired.

 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, adjust the linkage positions for the desired control response if necessary. See the table to the below:

Center of Gravity (CG)

The CG location is measured from the leading edge of the wing. This CG location has been determined with the recommended Li-Po battery (SPMX22003S30) mounted all the way forward.
Begin with the battery all the way to the rear of the battery compartment when running a battery larger than a 3S 2200mAh. Always confirm the CG is located correctly when changing the battery configuration.

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.

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.

In Flight Trimming

During the first flight, trim the aircraft for level flight at 3/4 throttle with flaps up. Make small trim adjustments with the transmitter’s trim switches to straighten the aircraft’s flight path.
After adjusting the trim, do not touch the control sticks for three 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 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), the control surfaces will react to aircraft movement. In some flight conditions oscillation may occur (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 the transmitter in low rate and use the flap switch to drop the flaps to takeoff or “half” position. Flaps make takeoffs shorter. Gradually increase the throttle to ¾ and steer with the rudder. As the tail comes off the ground, pull back gently on the elevator. When airborne, climb to a comfortable altitude and then flip the flap switch to level the flaps.
Flying
With the recommended battery pack (SPMX22003S30) set the transmitter timer or a stopwatch to five minutes. After five minutes, land the aircraft. Adjust the 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  utoff (LVC) section for more details on maximizing battery health and run time.
Landing
Land the aircraft into the wind. Use a small amount of throttle for the entire descent. Lower the throttle to ¼ and flip the flap 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.
Keep the throttle on until the aircraft is ready to flare. During 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, 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 the receiver is replaced, install the new receiver in the same orientation as the original receiver or damage may result.
NOTICE: Crash damage is not covered under warranty.
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 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 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 paint. DO NOT handle the aircraft until accelerant fully dries.

Flying Off Water

Flying off water poses a higher risk because piloting errors or water conditions can cause the aircraft to become stranded. Only fly from the water when a level of comfort has been achieved flying the aircraft from the ground. Never fly near people fishing, swimming, or playing.
Pre-Flight
Ensure the optional floats are secure on the fuselage and the water rudder is correctly connected and operating with the main rudder before putting the aircraft in the water.
Select an area to fly that does not have water currents, salt water, or debris. Look around the flight area and be aware of trees, docks, buoys, or other obstacles. Always fly with a
spotter and avoid swimmers, boaters, people fishing, and people on the beach.
Taxiing
When taxiing, use low throttle settings and the rudder to steer. Hold up elevator to help keep the rudder in the water and the nose of the floats above the surface. Steer into the wind when turning, and crab into the wind if crosswind taxiing is required. When turning or crabbing into the wind, apply aileron against the wind to keep the upwind side of the wing down and prevent the aircraft from being flipped over. Do not apply down elevator when the airplane is taxiing or during the takeoff run.
On Step
When speed increases with throttle, the floats will rise out of the water and begin to plane on the surface of the water, riding “on step.” The floats will come on step at a speed below flight speed, this is a transitional phase when the aircraft is not up to flight speed yet. This is considered a high speed taxi. Do not attempt to take off as soon as the aircraft comes on step. Use low to medium throttle and hold up elevator to manage speed on the water during a high speed taxi.

Takeoff
To lift off from the water, set the flaps to the takeoff position, hold up elevator and accelerate the aircraft to bring it on step. Relax the up elevator as the airplane comes on step and accelerate to flight speed with full throttle. When the aircraft is travelling at a sufficient speed, pull back slightly on the elevator to rotate for liftoff.
Landing
To land on the water, set the flaps to the landing position, and fly into the wind. Reduce the throttle to a low setting but keep some power during the approach. As the aircraft settles into ground effect, reduce the throttle fully and hold up elevator to flare. Hold up elevator through the touch down and as the airplane decelerates on the water.
WARNING: Never attempt to retrieve a downed aircraft by swimming unless you are sufficiently trained and/or there is another person available to respond in the case of an emergency.
CAUTION : Have a plan for retrieval in the event the airplane becomes stranded. Never retrieve a downed model in the water alone.
CAUTION: If at any time water splashes in the fuselage while flying from water, bring the airplane to shore, open the battery hatch and immediately remove any water that may have gotten in the fuselage. Leave the battery hatch open overnight to let the inside dry out and to prevent moisture damage to the electronic components. Failure to do so could cause the electronic components to fail, which could result in a crash.
TIP: Use a fishing pole with heavy line as a retrieval tool. Attach a tennis ball to the line, and throw the ball past a stranded aircraft to retrieve it.

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 bottom of the fuselage.

2. Mount the receiver using double-sided servo tape. The receiver may be mounted upright, upside down or on its side, but it should be square with the fuselage in its mounting position. The receiver cannot be mounted at an odd angle.
   TIP: For SAFE setups, install the receiver as close to the center of gravity of the aircraft as practical.

3. Connect the servos to their respective ports on the receiver using the chart below.

4. CAUTION : Incorrect installation of the receiver could cause a crash.
   Always perform a control surface check and AS3X control surface response test before flying a new setup, or after any setup changes.

IMPORTANT : When using Y-harness or servo extensions with Spektrum equipment, do not use reversing harnesses. Using reversing Y-harnesses or servo extensions may cause servos to operate erratically or not function at all.

AMA National Model Aircraft Safety Code

Academy of Model Aeronautics National Model Aircraft Safety Code

National Model Aircraft Safety Code
Effective January 1, 2018
A model aircraft is a non-human-carrying device capable of sustained flight within visual line of sight of the pilot or spotter(s). It may not exceed 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 humancarrying 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 of 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 willcomply 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 flightline, 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.
