Transmitter

RTFREADY-TO-FLY

Installing the Transmitter BatteriesYour Spektrum DXS Transmitter comes prebound to the aircraft.Remove the battery cover, install the four included batteries (noting proper polarity) and reinstall the battery cover.Low Battery AlarmWhen the transmitter battery voltage drops below 4.7 volts, an alarm sounds, and the voltage LEDs flash. The batteries must be replaced immediately. If this happens while flying, land your aircraft as soon and as safely as possible.CAUTION: If using rechargeable batteries, charge only rechargeable batteries. Charging non-rechargeable batteries may cause the batteries to burst, resulting in injury to persons and/or damage to property.

Explanation of DXS Transmitter LEDs, Switches, and Modes for the Habu STS.Trainer/Bind/Panic Button (I button):This switch is used as both the trainer and bind switch as well as the Panic Switch for your Habu STS. For complete binding instructions,  refer to the binding section below. When using the trainer function, connect the SRXL2 DSMX remote receiver (SPM9747, sold separately)  into the wireless trainer port of the master (instructor) transmitter. The master transmitter must be powered ON and bound to the aircraft receiver. The slave transmitter must be powered OFF. Any time you press and hold the trainer button on the master, it will give control authority to the slave. Releasing the trainer button returns control to the master.IMPORTANT: The slave transmitter must always have the same settings as the master. See Flight Training section for setup of other  Spektrum Transmitters.Hi/Lo Rate Switch (F Switch):This switch supports high and low rate functions on aileron, elevator, and rudder channels. In the upper, or “HI” position, servo travel is  100% on these channels. In the lower, or “LO,” position, servo travel decreases to 70%. This switch lets you quickly change control rates from high for aggressive maneuvers to low for smooth, precise maneuvers. When learning to fly, use low rate.Flight Mode Switch (A Switch):This switch is used to select the SAFE Flight mode. For other conventional receivers, this switch controls a servo connected to the Channel 5/Gear port.

RGB LEDs:Flashing with beeps- Bind mode when Trainer (Bind) switch is held and the transmitter is powered on (see Binding instructions).Pulsates with one low tone beep every 2 seconds (when transmitter battery voltage drops below 4.7 volts). Replace the transmitter batteries immediately. If this happens while flying, land your aircraft as soon and as safely as possible.

Battery Voltage LevelThe included DXS transmitter includes a new flight battery voltage level indicator feature.LED SMART Battery voltage indication is based on current-voltage and will change with throttle/power usage. When the throttle is increased,  voltage drops, causing the bars to indicate lower power (e.g., fewer LEDs solid or flashing.) When the throttle is lowered to idle/off, the bars recover (e.g., more LEDs solid or flashing). LED bars will rise and lower depending on throttle/power usage.

The SMART Battery low voltage alarm sounds when the ESCs are close to reaching low voltage cutoff. The alarm will sound for 25 seconds.  If the throttle is lowered to allow voltage recovery, the alarm will stop early. Land the aircraft when the alarm sounds.After landing, reset the SMART Battery low voltage warning by either (1) powering cycling the DXS transmitter, or (2) disconnecting the battery from the aircraft for more than 15 seconds or until the LED voltage indication bars go out.Connect a fully charged battery to the aircraft, which will ensure the SMART Battery low voltage warning resets prior to the next flight.

Transmitter Setup

If using any DSMX transmitter other than the included DXS (3 position gear switch, RTF only) the radio will have to be configured correctly for the SAFE system to work properly.

• SAFE Flight mode is selected using Channel 5 signal (high, middle, low)• Panic mode is selected with Channel 6 signal (high, low)

Refer to your transmitter’s manual for more information about transmitter setup.If using a 2 position switch for SAFE flight modes, only Beginner andExperienced modes will be active.BNF Transmitter Telemetry SetupIf 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.

The flight controller should be mounted in the orientation shown, parallel to the length of the fuselage, with the label facing up and the servo ports facing the rear of the aircraft. The orientation of the flight controller is critical for all AS3X® and SAFE® technology setups.CAUTION: Incorrect installation of the flight controller could cause a crash.

Transmitter and Receiver Binding

Binding is the process of programming the control unit to recognize the GUID (Globally Unique Identifier) code of a single specific transmitter.The aircraft should be bound to the transmitter at the factory, but if you need to re-bind them, follow these steps. If your aircraft does not  respond to the transmitter when the batteries in the aircraft and transmitter are fully charged, your aircraft and transmitter may need to be re- bound using the instructions in the chart.IMPORTANT: The throttle will not arm if the transmitter’s throttle control is not put at the lowest position. If you encounter problems,  follow the binding instructions and refer to the transmitter troubleshooting guide for other instructions. If needed, contact the appropriate Horizon Product Support office.* FailsafeIf 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 for the aircraft to slowly circle and descend until radio link is re-established.

√	Binding Procedure
1. Make sure the transmitter is powered off.
2. Make sure the transmitter controls are neutral, the  throttle is in the low position, and the aircraft is immobile.*
3. Connect the flight battery to the ESC. The Flight  Controller LED will begin to flash red and blue.
4. On the remote Spektrum receiver that is connected to  the flight controller, press and release the bind button.  The receiver LED will flash rapidly.
5. Press and hold the Bind button on the top of the  transmitter while turning ON the power switch.
6. When the receiver binds to the transmitter, the  receiver LED will be solid ON.
Once bound the receiver and transmitter should retain their bind for future flights.

Flight Battery Installation, SAFE system and Electronic Speed Control (ESC) Arming

1. Rest the aircraft on its landing gear on a flat surface.
2. Lower the throttle and turn on the throttle hold switch, then power on the transmitter for at least 5 seconds.
3. Press the latch button (A) and remove the canopy.
4. Secure the flight battery (B) in the battery compartment using the hook and loop straps (C) so that the aircraft has a balanced Center of Gravity (CG).
5. Connect the flight battery to the aircraft.TIP: Connect the battery to the flight controller plug before securing the battery. Then secure the battery with the hook and loop straps. Important: Before flying, refer to the “Verifying Your Aircraft’s Center of Gravity (CG)” section for details about final battery placement.6. Replace the canopy.The aircraft should be on level ground and must be kept immobile while the SAFE system initializes. If the aircraft does not initialize after about 30 seconds because of too much movement, disconnect and reconnect the flight battery to re-initialize the system.After the SAFE system initializes, the rudder will move back and forth, then come to neutral to indicate the SAFE system has initialized and is ready to operate. If you accidentally connect the battery while the throttle is not a its lowest position, the ESC will not arm the motor. Reduce throttle to lowest setting for motor to arm.

IMPORTANT: SAFE technology is not active until you advance the throttle past 25%. Once it is active, the control surfaces may move on the aircraft. This is normal. The SAFE technology will remain active until the ESC is turned off.

CAUTION: Always disconnect the Li-Po flight battery from the aircraft receiver when not flying to avoid over-discharging the battery.  Batteries discharged to a voltage lower than the lowest approved voltage may become damaged, resulting in loss of performance and potential fire when batteries are charged.

Center of Gravity (CG)

An aircraft with a correct CG has its weight balanced at a calculated point where the entire airframe will balance when suspended at that point. After installing the battery (in the recommended position) and before powering on the ESC switch, verify the CG by supporting the aircraft 90-95mm (approximately 3.74 inches) back from the wing root, as shown.3S 4000mAh Smart battery CG position- The battery is installed all the way forward in battery compartment. Only the front battery strap will be used.4S 4000mAh Smart battery CG position- The battery is installed centered in the battery tray, using both front and rear battery straps. Balance the aircraft on your fingertips near the fuselage under the wings.

• If the nose goes down, move the flight battery back until the aircraft balances.
• If the nose goes up, move the flight battery forward until the aircraft balances.

When flying with correct CG in beginner mode, the aircraft should climb gradually at full power and fly level at 50%–60% power with no elevator input. If the aircraft CG is too far forward (nose heavy), up elevator is required to fly level at 50%–60% power. If the aircraft CG is too far aft (tail heavy), down elevator is required to fly level. Adjust the battery position as needed.

Control Direction Test

WARNING: Do not perform this or any other equipment test with the propeller installed on the aircraft. Serious injury or property damage could result from the motor starting inadvertently.

1. Set the flight mode switch to Experienced mode (position 2).
2. Keep the throttle at zero and place the model on level ground away from obstacles.
3. Move the sticks on the transmitter as described in the table to ensure the aircraft control surfaces respond as shown.

If the control surfaces do not respond as shown, DO NOT FLY. Refer to the Troubleshooting Guide for more information. If you need more assistance, contact the appropriate Horizon Hobby Product Support department.If the aircraft responds as shown, continue on to the Flight Control section.

Choose a Flying Field

Consult local laws and ordinances before choosing a location to fly your aircraft.

In order to have the most success and to protect your property and aircraft, it is very important to select a place to fly that is very open.Remember, your aircraft can reach significant speeds when flying and can cover ground quickly. Plan on flying in an area that gives you more space than you think you need, especially with first flights.

The flying site should:

• Have a minimum of approximately 1300 feet(400m) of clear space in all directions.
• Be clear of people and pets.
• Be free of trees, buildings, cars, power lines or anything that could entangle your aircraft or interfere with your line of sight.

Range Test

WARNING: While holding the aircraft during the range test, always keep body parts and loose items away from the motor. Failure to do so could cause personal injury.

Before each flying session, and especially with a new model, you should perform a range check. If you have the PNP aircraft, refer to your transmitter manual to perform a range check of your system.

The RTF included DXS transmitter incorporates a range check mode to reduce the output power of the transmitter. Follow the directions below to enter range check mode for the DXS transmitter:

1. Power on the transmitter for 5 seconds or more with the throttle stick and trim low. Plug in the aircraft battery and keep the aircraft immobile for 5 seconds.
2. Face the model with the transmitter in your normal flying position.
3. Toggle (back and forth = 1 toggle) the HI/LO Rate switch rapidly 4 times and then press and hold the bind button. The transmitter  LEDs will flash and the alarm will sound. The system is in range check mode. Do not let go of the bind button until you are finished with the range check.IMPORTANT: You must hold the BIND/Panic button during the entire range check process. Releasing the button will exit the range check mode.
4. With the radio system powered on and the model restrained on the ground, stand 28 meters (90 feet) away from the model.TIP: In some aircraft, when the model is placed on the ground, the antenna(s) can be within inches of the ground. Close proximity of the antenna(s) to the ground can reduce the effectiveness of the range check. If you experience issues during the range check, restrain the model on a non-conductive stand or table up to 2ft (60cm) above the ground, then range check the system again.
5. Move the transmitter rudder, elevator, aileron, and throttle control to ensure they operate smoothly at 28 meters (90 feet).
6. If control issues exist, do not attempt to fly. Refer to the contact table at the end of this manual to contact Horizon Hobby product support. Also, see the Spektrum website for more information.
7. When the range check is successfully completed, release the bind button to exit range check mode.

CAUTION: Due to the reduced output power of the transmitter, NEVER attempt to fly while the transmitter is in range check mode. Loss of control will occur.

Sensor Assisted Flight Envelope (SAFE) Technology Flight Modes

At any time during a flight you can switch between the 3 flight modes or use Panic recovery to get your aircraft to a safe flying attitude.  Change between flight modes by changing the flight mode switch position.

Beginner Mode (position 0)

Flight Controller LED Blue

• Envelope limit: Pitch (nose up and down) and Roll (wing tips up and down) angles are limited to help you keep the aircraft airborne.
• Self-leveling: when the pitch and roll controls are returned to neutral, the aircraft returns to level flight.
• Stability assisted takeoff and landing.
• Throttle-based climb and descent.

Intermediate Mode (position 1)Flight Controller LED Purple• Natural Flight Experience: In normal training flight conditions, the pilot experiences natural AS3X® flight for smooth handling and outstanding precision.• Large Flight Envelope: The pilot is only prevented from entering extreme flight conditions outside the training flight envelope.TIP: When flying Intermediate Mode, the Habu STS will automatically be in beginner mode when below 100 feet.

Panic RecoveryThis function is intended to provide you with the confidence to continue to improve your flight skills. If you become disoriented or the aircraft is in an unknown or uncomfortable attitude in any flight mode:

1. Press and hold the Bind/PANIC button on the transmitter and release the control sticks. The aircraft will immediately pull out of a dive and roll wings upright and level.IMPORTANT: The aircraft will recover to a safer attitude even if sticks are held while holding the PANIC button. However, release the control sticks for the quickest recovery.
2. Release the PANIC button and continue your flight.

CAUTION: The Panic Recovery function will not avoid obstacles in the aircraft flight path. Sufficient altitude is required for the aircraft to return to straight and level flight if the aircraft is upside down when the panic function is applied.

Flight Control

IMPORTANT: Even though SAFE technology is a very helpful tool, the aircraft still needs to be flown manually. If incorrect input is given at lower altitudes or at slower speeds, the aircraft can crash. Study these control inputs and the aircraft response to each carefully before attempting your first flight.  For first flights, set the SAFE® flight mode switch to Beginner Mode (position 0). For smooth control of your aircraft, always make small corrections. All directions are described as if you were sitting in the aircraft.

Flying faster or slower: When your aircraft is stable in the air, push the throttle stick up to make the aircraft go faster. Pull the throttle stick back to slow down. The aircraft will climb when the throttle is increased.Elevator up and down: Push the elevator stick forward to make the aircraft go down. Pull the elevator stick back to go up.Aileron right and left: Move the aileron stick right to make the aircraft roll or “bank” right. Move the aileron stick left to bank left.TIP: Always picture yourself in the aircraft when determining which way to bank the aircraft wings. When the aircraft is flying away from you, banking the aircraft right or left appears normal. When flying toward you, the aircraft will appear to bank the opposite direction to the control input given. This will become more instinctual with experience.

Rudder left and right: Push the rudder stick left or right to yaw or point the nose of the aircraft left or right. The rudder stick is also used to steer the aircraft left and right while taxiing on the ground.TIP: Similar to aileron control, picture yourself in the aircraft to determine which direction to point the nose whether you are flying away from yourself or toward yourself.

Flight Training

InstructionTo the new pilot:This aircraft is easy to fly and helps you apply beginner skills to flying; however, we recommend you get help from a qualified flight instructor for your first radio-controlled flights. Some model flying clubs provide flight training at their flying fields. Find a nearby flying club through your local hobby shop. In the  U.S., visit the Academy of Model Aeronautics at www.modelaircraft.org for more information on clubs and flight instruction.

To the flight instructor:Feel free to experiment with the SAFE technology before instructing your student on this aircraft. The progressive switch positions in the SAFE technology are intended for a new pilot to learn with minimal instructor assistance. We recommend using Channel 5 Switch Position 1 to instruct a new pilot. Switch positions 0 and 2 may stabilize the aircraft more or less than you desire for instruction purposes.

RTFRADY-TO-FLY

DXS Wireless Trainer FeatureYour DXS transmitter may be connected to another transmitter through the SRXL2 DSMX Remote Receiver (SPM9747, sold separately).

The DXS transmitter is ideal as the master as it is compatible with all Spektrum transmitters when using this feature. Servo reversing and trims must be the same on both transmitters.

This “buddy box” approach has helped many new pilots get the feel for aircraft control with the close assistance of a flight instructor. Connecting two transmitters enables your flight instructor to hold the master transmitter while you hold the slave transmitter. While you learn to fly, the instructor holds the trainer switch to give you control of the aircraft. If you need help, the flight instructor can release the switch to take control.

IMPORTANT: If a transmitter other than the included DXS is used for master or slave, refer to Buddy Box Setup in this manual.

Remote Receiver Installation1. Open the battery door2. Connect the remote receiver cable to the wireless trainer port.3. Install the remote receiver in the cavity behind the battery door with double-sided tape.

Buddy Box SetupIMPORTANT: If using the buddy box option for training on a transmitter other than the included DXS use these settings for a Master and or Slave  Transmitter. Failure to do so will not allow SAFE technology Flight modes to work correctly.

Preflight Checklist

√

1. Find a safe open area to fly.

2. Charge the flight battery.

3. Install a fully charged flight battery in the aircraft.

4. Make sure all linkages move freely.

5. Check the Center of Gravity (CG).

6. Perform the control direction test

7. Perform a radio system range test.

8. Plan flight for flying field conditions.

9. Set a flight time for:4-6 minutes using a 3000mAh 3S battery pack.8-10 minutes using a 4000mAh 3S battery pack.

10. Have Fun!

Flying

TakeoffSet the flight mode switch to Beginner Mode (position 0) for your first flights. Set a flight timer for 5 minutes for initial flights. Depending on your battery selection, adjust timer.TIP: The included DXS transmitter includes a new flight battery voltage level indicator feature. See page 6 for more details.TIP: When battery reaches LVC, the motor will pulse on/off for about 30 seconds before motor shuts off indicating it is time to land. Adjust timer accordingly.

Ground LaunchOnce the aircraft is ready for flight, slowly advance the throttle to start the takeoff roll into the wind. Small rudder inputs may be required for heading correction as the aircraft will begin a slow climb out as the throttle is advanced.TIP: Rudder/nose wheel control throw is automatically set for taxi mode in beginner mode when on the ground and under 6 meters of altitude.This provides more control to taxi the aircraft and yaw control during landings.Once airborne, rudder control throw is automatically reduced to beginner flight mode.

In FlightLet the aircraft climb at full throttle, into the wind, until the aircraft reaches about 50 feet. Gradually turn the aircraft away from you while still maintaining altitude. Climb to about 200 feet and reduce the throttle to about half throttle stick position. Try not to get the aircraft too high or far away. It will make it difficult to see.Make small and gentle stick movements to see how the aircraft responds.

Flying with the nose pointed toward you is one of the hardest things to do when learning to fly. Practice flying in large circles high off the ground.

If you lose the orientation of the aircraft, press and hold the PANIC button and the aircraft will return to level flight.

NOTICE: If a crash is imminent, activate throttle hold or quickly lower the throttle and throttle trim. Failure to do so could result in extra damage to the airframe, as well as damage to the ESC and motor.

Low Voltage Cutoff (LVC)LVC is a function built into your ESC to protect the battery from over-discharge. When the battery charge is low, LVC limits power supplied to the motor.  The aircraft will begin to slow and you will hear the motor pulse. When the motor power decreases, land the aircraft immediately and recharge the flight battery.NOTICE: Repeated flying to LVC will damage the battery.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.

Land the aircraft

1. Reduce the throttle to around 50% to slow the airspeed.
2. Fly the aircraft downwind past the end of the runway.
3. Turn the aircraft into the wind and line the aircraft up with the runway center line.
4. Decrease the throttle further and begin descending towards the runway, keeping the wings level during approach. Try to have the aircraft at 10ft altitude as it passes over the threshold of the runway.
5. As the aircraft passes over the threshold of the runway slowly decrease the throttle.
6. Just as the aircraft is about to touch down, gently pull back on the elevator to raise the nose and flare for a gentle landing.

NOTICE: If a crash is imminent, activate throttle hold or quickly lower the throttle. Failure to do so could result in extra damage to the airframe, as well as damage to the ESC and motor.IMPORTANT: When finished flying, never keep the aircraft in the sun. Do not store the aircraft in a hot, enclosed area such as a car. Doing so can damage the foam.

Trimming the Aircraft

Adjusting Trim in flightIf your aircraft does not fly straight and level at half throttle with the sticks at neutral, fly into the wind and adjust the trim sliders as indicated in the table until the aircraft maintains a reasonably straight and level flight path.• Trimming is best done in calm wind conditions.• The SAFE flight mode switch should be set to Experienced mode (position 2) before adjusting the trims.

After the aircraft is trimmed in flight, land the aircraft and proceed to the Manually Adjusting Trim section to set the trim mechanically.

The included RTF DXS transmitter features electronic trim buttons. The transmitter emits a faint beep with each click of the trim buttons in either direction. Holding the button in either direction quickly adjusts the trim several steps until the button is released or until the trim reaches the end of its travel. If the trim button does not beep when clicked, the trim is at the far end of its travel. Center trim is indicated by a slightly louder beep.TIP: Trim the aircraft at a sufficient altitude of 30 meters (about 100’). Having an experienced flight instructor trim your aircraft during the first flight is recommended.

Manually Adjusting TrimThe SAFE flight mode switch should be set to Experienced mode (position 2) before manually adjusting the trim settings.The aircraft should be kept still while performing manual adjustment of trim.With the trim settings from the trim flight still set in the transmitter, take note of the positions of each of the control surfaces, one at a time.Adjust the clevis on each control surface to position the surface the same as it was with the trim offset.1. Remove the clevis from the control horn.2. Turn the clevis (as shown) to lengthen or shorten the pushrod.3. Close the clevis onto the control horn and slide the tube towards the horn to secure the clevis.4. Move to the next control surface.When you have all of the surface trims centered, return the trim settings on the transmitter to neutral by pushing the trim buttons for each surface until the transmitter emits a loud beep indicating center trim.

Factory settings for the Control Horns and Servo Arms

The Illustration shows recommended hole settings in the servo arms and control horns.

Post Flight

1. Disconnect the flight battery from the ESC (Required for Safety and battery life).
2. Power OFF the transmitter.
3. Remove the flight battery from the aircraft.
4. Recharge the flight battery.
5. Repair or replace all damaged parts.
6. Store the flight battery apart from the aircraft and monitor the battery charge.
7. Make note of the flight conditions and flight plan results, planning for future flights.

Optional Landing Assist Sensor (LAS) Upgrade

The Habu STS is upgradable with the addition of the optional LAS module (SPMA3180 not included) this allows the advanced SAFE features to be combined with a Landing Assist Sensor (LAS) for smoother gentler landings.

IMPORTANT: For best results when using LAS, land on grass surfaces or a light-colored surface, such as light-colored concrete. Black surfaces or water normally do not have enough reflection for the sensor to receive accurate readings.

Installation of the LAS module

1. Rotate the aircraft to access the bottom of the fuselage.
2. Press the factory-installed plug (A) to release it. Then removed it from the LAS pocket. Save the plug for flights without LAS module.
3. Feed the LAS connector through the channel in the base of the LAS pocket.
4. Align the LAS module with the wires facing the back of the aircraft.Place the LAS module into the pocket and press it to secure it into place with a click.
5. Place the aircraft on its landing gear and connect LAS connector to Channel 7 on the flight controller. For correct polarity of the plug ensure that the  orange (not brown) signal wire (B) is facing towards the front of the aircraft when plugged into the flight controller.

Landing with LASReduce throttle, keep the wings level and slowly reduce the altitude of the aircraft. When the aircraft’s landing approach reaches an altitude of roughly 1m  the LAS will level off the aircraft, manage the throttle, and then flare the aircraft for a touchdown.IMPORTANT: LAS is functional for all SAFE flight modes except for Experienced Mode. When the flight mode is switched to Experienced mode the  LAS is deactivated and the pilot will have zero assistance on landing, a traditional manual landing of the aircraft is necessary.IMPORTANT: Installation of the LAS module is not auto land. The aircraft must be guided and aligned with the landing strip for landing.TIP: If the speed of the aircraft is too fast for landing or above 20% throttle setting, LAS is not effective.TIP: If the Aircraft’s landing approach is too low and fast, LAS will not flare.

Service and Repairs

NOTICE: After any impact or replacement, always ensure the receiver and flight controller are secure in the fuselage. If you replace the receiver or flight controller, install the new receiver in the same orientation and manner as the original receiver or damage may result.Repairs to the wings and fuselage of this aircraft can be made easily using virtually any adhesive (hot glue, regular CA (cyanoacrylate adhesive), 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 back of this manual.
