600 feet (183 m) Fly in this area (upwind of pilot) Stand here Wind 0–7 mph (0–11km/h)Flying Tips
- Sensor Assisted Flight Envelope (SAFE™) technology is designed as flight assistance, not an autopilot. The pilot is always in control and required to fly the aircraft at all times.
- Start in Beginner mode (SAFE switch position 0). As you learn and become more confident, change modes to advance your flying skills.
- Always keep your aircraft in plain sight and upwind from you.
- Do not attempt your first turn at low altitude. Higher altitudes allow for greater possibility of correction.
• Always make deliberate and steady control stick movements for smooth control of your aircraft. - Do not fly in winds greater than 8-10 mph. If flying in winds 5-10mph and in beginner Mode (SAFE positon 0), you will likely need to fly in High Rates.
| Preflight Checklist | √ | |
| 1. | Find a safe and open area. | |
| 2. | Charge flight battery. | |
| 3. | Install flight battery in aircraft. | |
| 4. | Perform Control Direction Test. | |

√ Binding Procedure Reference Table
| 1. Make sure the transmitter is powered off. | |
| 2. Make sure the transmitter controls are neutral, the throttle and throttle trim are in the low position, and the aircraft is immobile. | |
| 3. Install a bind plug in the receiver bind port. | |
| 4. Connect the flight battery in the aircraft. The receiver LED will begin to flash. | |
| 5. Power on the transmitter while holding the transmitter bind button. | |
| 6. When the receiver binds to the transmit-ter, the light on the receiver will turn solid and produce a series of three ascending tones. The tones will indicate the ESC is armed, provided the throttle stick and throttle trim are low enough to trigger arming. | |
| 7. Release the Bind button and remove the bind plug from the receiver. | |
| 8. Confirm that the aircraft is bound by moving controls. |
The receiver should retain the binding instructions received from the transmitter until another binding is done.

Bind-N-Fly.* Ready to fly, redefined.
Transmitter and Receiver Binding
Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single specific transmitter.
You need to 'bind' your chosen Spektrum™ DSM2/DSMX technology equipped aircraft transmitter to the receiver for proper operation.
Please visit www.bindnfly.com for a complete list of compatible transmitters.

Flying
- In Beginner mode, when properly trimmed, your aircraft will climb at full throttle without use of the elevator stick.
- Make small and steady control stick movements for smooth control of your aircraft.
- Let the aircraft climb at full throttle, into the wind, until the aircraft gets about 150 feet (46 meters) above the ground, then decrease the throttle to half (50%).
- Flying with the nose pointed toward you is one of the hardest things to do when learning to fly. To practice piloting the aircraft, try flying in large circles high off the ground.

| Post Flight Checklist | √ | |
| 1. | Disconnect flight battery from aircraft (Required for Safety). | |
| 2. | Remove flight battery from the aircraft. | |
| 3. | Power off transmitter. | |
| 4. | Recharge flight battery. | |
| 5. | Repair or replace all damaged parts. | |
| 6. | Store flight battery apart from the aircraft and monitor the battery charge. | |
| 7. | Make note of flight conditions and flight plan results, planning for future flights. | |
Landing
Land the aircraft in Beginner mode.
CAUTION: Never catch a flying aircraft in your hands. Doing so could cause personal injury and damage to the aircraft.

Easy Landing
Landing is easier if you hold the Panic Recovery button. Line up for your landing, decrease the throttle to 0% and press and hold the Panic Recovery button. The aircraft will glide down wings level with the nose up (flared) for landing.


text_image
0 A 1 - 2 T CH 5NOTICE: If a crash is imminent, reduce the throttle. Failure to do so could result in extra damage to the airframe, as well as damage to the receiver and motors.
NOTICE: Crash damage is not covered under warranty.
Post Flight
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 foam.
Adjusting Trim in Flight
Move the trim sliders for the controls as they are assigned on your transmitter. Familiarize yourself with your transmitter's controls and the aircraft's response before flying by performing the recommended Control Direction Test.
Elevator trim:
Trim the elevator at 50%-60% throttle. When the elevator is trimmed correctly, your aircraft will fly level at half throttle, climb steadily above half throttle and descend below half throttle.
- If the aircraft's nose drifts up or down while the elevator stick is at neutral (centered) position, move the elevator trim slider by one or two "click" increments in the SAME direction as the drift.
Aileron trim:
When trimmed correctly, your aircraft flies with wings level.
- If the aircraft drifts left or right when the aileron stick is at neutral (centered) position, move the aileron trim slider by one or two "click" increments OPPOSITE the direction of roll.
If you must use more than 8 "clicks" on a trim slider to make the aircraft fly straight and level, land and adjust a control surface as described below.
Manually Adjusting Trim
Perform manual adjustment of trim before increasing the throttle above 25% or SAFE will move the control surfaces when the aircraft is moved.
Return any trim setting on the transmitter to neutral by pushing the trim slider to the middle position, then adjusting the clevis on that control surface to position it the same as it was with the trim slider offset.
- Remove the clevis from the control horn.
- Turn the clevis (as shown) to lengthen or shorten the pushrod.
- Close the clevis onto the control horn and slide the tube towards the horn to secure the clevis.

Service and Repair
Thanks to the Z-Foam ^™ material in the wing and fuselage of this aircraft, repairs to the foam can be made 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.

CAUTION: DO NOT handle a propeller, motor or ESC while the flight battery is connected to the ESC. Personal injury could result.
Disassembly
- Remove the spinner (A) by carefully pulling it away from the propeller (B).
- Hold the motor shaft (C) in place, then pull the propeller from the motor shaft.
- Remove 3 screws (D) from the motor cowling under the wing.
- Remove the cowling (that contains the motor) from the wing. Paint may keep the cowling attached to the wing.
- Remove 2 screws (E) from the front of the cowling that secures the motor.
- Disconnect the motor wires from the ESC wires.
- Remove the motor (F) and motor wires from the wing.
- Assemble in reverse order.
- Correctly center and attach the spinner to the propeller hub using CA (cyanoacrylate adhesive).
NOTICE: Make sure the propeller size numbers (4.75x2.5R for right side and 4.75X2.5L for left side) face out from the motor.

text_image
Wiring not shown.Prolong Battery Life
- Low Voltage Cutoff (LVC) pulses the power to the motors when the voltage gets low. When the motors pulse, land the aircraft immediately and recharge the flight battery.
- The aircraft can fly as recommended for approximately 8 minutes on one battery charge. Set a timer or stopwatch to let you know when it is time to land. However, if the motor begins to pulse (hits LVC), land immediately.
NOTICE: Repeated flying to LVC will damage the battery.
