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 bind 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.
Preflight

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: Assigned switch toggles between SAFE Select mode and AS3X mode

Battery Installation and ESC Arming
Battery Selection
A 3S 2200-3200mAh LiPo battery is required. Refer to the Optional Parts List for battery recommendations. 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.
CAUTION: Add nose weight for lighter batteries. Always verify the model balances within the recommended CG range before flying. Attempting to fly the model with an aft CG will cause the model to be unstable.
CAUTION: Never adjust the CG while a battery is connected.
CAUTION: When replacing the wheels with floats, recheck the CG. Place the battery further forward to compensate for the CG change.
1. For added security, apply the loop side (soft side) of the optional hook and loop tape to the bottom of your battery, and the hook side to the battery tray.
2. Remove the battery hatch. 3. Install the fully charged battery in the center of the battery compartment as
shown. Secure using the hook and loop straps. 4. Connect the battery to the ESC. Two beeps indicate the ESCs are armed.
CAUTION: Always keep hands away from the propeller. When armed, the motor will turn the propeller in response to any throttle movement.
5. Keep the aircraft immobile and away from wind or the system will not initialize. · The motor will emit two even tones when the battery is connected and the ESC has a throttle signal. · The receiver LED will illuminate orange when it is initialized. · Fast continuous beeps indicate the ESCs are not armed.
6. Reinstall the battery hatch.

SAFE® Select Switch Designation
SAFE® Select technology can be assigned to any open switch (2 or 3 position) controlling a channel (59) 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 59. 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.
Control Surface Centering
After assembly and transmitter setup, confirm that the control surfaces are centered. The model must be powered up 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 subtrims on your transmitter are 0.
2. Power up the model in AS3X mode and leave the throttle at 0.
3. Verify the control surface tips are mechanically centered.

Assigning a Switch
1. Bind the aircraft to choose SAFE Select ON. This will

Mode 1 and 2 Transmitters

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.

AS3X Control Direction Test (BNF)
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 (BNF)
During your first flight, trim the aircraft for level flight at 1/2 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 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.
Getting Started
Before you fly, range check the radio system. Refer to your specific transmitter instruction manual for range test information. When you first connect the battery to the airplane AS3X will not be active. After advancing the throttle the first time, the AS3X system will be active and it is normal to see the control surfaces react to aircraft movement. For your first flights set your transmitter timer or a stopwatch to 5 minutes. Adjust your timer for longer or shorter flights once you have flown the model.
Takeoff
Face the aircraft into the wind for takeoff. Set your transmitter to low rates and drop the flaps to takeoff position (half position). Flaps are not required, but lowering them makes takeoffs shorter.
Gradually increase the throttle to full, and steer on the ground with rudder as necessary to keep the aircraft rolling straight. Be aware the nose wheel will become more sensitive as speed increases. Leave the elevator at neutral and allow the aircraft to accelerate up to speed on the ground, then pull up gently on the elevator to rotate for takeoff. When airborne, climb to a comfortable altitude, and return the flaps to the level position.
Flying
For your first flights climb to a moderate altitude and get comfortable with the aircraft while the battery is fresh. Get a feel for the aircraft’s low speed performance with the flaps up and down at a safe altitude (approximately 100 feet or more) before being required to make your first landing attempt. Land the aircraft when the timer expires. 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
Plan to land the aircraft into the wind when possible. Fly downwind and turn into the wind to begin the approach. Lower the throttle and lower the flaps to the landing position (full down position.) Flaps will make the landing approach steeper and slower, and allow for a smoother landing. If there is a significant crosswind, only lower the flaps to the takeoff position (middle position) which will help maintain speed and better directional control during approach.
During the approach and descent, keep the wings level and the aircraft pointed into the wind. The angle of attack (the angle between the aircraft’s pitch attitude and the horizon) should remain consistent and slightly nose high during the decent. With the angle of attack maintained during the descent, the speed and descent rate is mostly controlled with small throttle changes. Stay into the throttle to maintain speed and control during decent until the aircraft is ready to flare. As the airplane descends into ground effect, fully lower the throttle, pull the nose up more to bleed off airspeed (flare), and the aircraft will settle on its wheels.

Once on the ground leave the elevator neutral and 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 too much 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).
Oscillation
For most flight maneuvers the aircraft should fly smoothly and normal, but it is possible 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.
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 CA accelerant on your aircraft can damage paint. DO NOT handle the aircraft until accelerant fully dries.

SAFE Select Flying Tips
When flying in SAFE Select mode the aircraft will return to level flight any time the aileron and elevator controls are at neutral. Applying aileron or elevator control will cause the airplane to bank, climb or dive, and the amount the stick is moved will determine the attitude the airplane flies. Holding full control will push the aircraft to the pre-determined bank and roll limits but it will not go past those angles.
When flying with SAFE Select it is normal to hold the control stick deflected with moderate aileron input when flying through a turn. To fly smoothly with SAFE Select avoid making frequent control changes and don’t attempt to correct for minor deviations. With SAFE Select, 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 Select mode to AS3X mode. If you do not neutralize controls when switching into AS3X mode, the control inputs used for SAFE Select mode will be excessive for AS3X mode and the aircraft will react immediately.

Differences between SAFE Select and AS3X modes
This section is generally accurate but does not take into account flight speed, battery charge status, and many other limiting factors.
· In SAFE Select mode the aircraft will self level when the control stick is neutralized. In AS3X mode the aircraft will continue to fly at its present attitude when the control stick is neutralized.
· In SAFE Select mode holding a small amount of control will result in the model banking or pitching to a moderate angle and remaining at that angle as long as the control stick doesn’t move. In AS3X mode holding a small amount of control will result in the model continuing to pitch or roll at a slow rate as long as the control stick doesn’t move.
· In SAFE Select mode holding full control will result in the airplane banking or pitching to the predetermined limits and the aircraft will keep flying at that attitude as long as the control stick is fully deflected. In AS3X mode holding full control will result in the aircraft pitching or rolling as fast as possible, and it will continue to rapidly change attitude as long as the control stick is fully deflected.

Float Assembly and Installation
1. Remove the screw on the bottom of the fuselage, and remove the landing gear cover.
2. Loosen the nose wheel assembly screw, and remove the nose wheel assembly from the nose wheel steering bracket.
3. Loosen the six 2mm x 10mm mounting screws from the landing gear mounting clamps. Remove the mounting clamps (screws attached) and set them aside.
4. Install the front and rear float struts in the fuselage. The float struts angle down at the ends; the wheel strut is straight out, away from the plane.
5. Reinstall the landing gear cover and tighten the fuselage screw.
6. Install the floats and the spreader bars onto the struts, using the plastic clamps and the 2mm x 10mm screws to secure each clamp.
7. Install the steering wire, slipping the z-bend into the steering arm and snapping the rear clip into the water rudder clevis.
8. Secure the pushrod sleeve to the rear spreader bar with the included zip tie.
Tip: If you removed the steering arm for the water rudder for flying with wheels, reinstall it for flying with floats.
Disassemble in reverse order.
NOTICE: If installing floats, always recheck the center of gravity before attempting to fly. Failure to do so may result in a crash.

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.
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 rudders 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.
