Transmitter and Receiver Binding

For a list of compatible DSM2/DSMX transmitters, please visit www.bindnfly.com

✓ Binding Procedure
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.
	1. Refer to your transmitter's unique instructions for binding to a receiver (location of transmitter's Bind control).
	2. Make sure the flight battery is disconnected from the aircraft.
	3. Ensure the transmitter is powered OFF.
	4. Connect the flight battery to the aircraft and turn the aircraft upright. The receiver LED will begin to flash (typically after 5 seconds).
	5. Ensure that control surface trims are centered and the throttle and throttle trims are in the low position to correctly set the failsafe.
	6. Put your transmitter into bind mode. Refer to your transmitter's manual for binding button or switch instructions.
	7. After 5 to 10 seconds, the receiver status LED will turn solid, indicating that the receiver is bound to the transmitter. If the LED does not turn solid, refer to the Troubleshooting Guide at the back of the manual.

For subsequent flights, power ON the transmitter for 5 seconds before connecting the flight battery.

Low Voltage Cutoff (LVC)

When a Li-Po battery is discharged below 3V per cell, it will not hold a charge. The aircraft's ESC protects the flight battery from over-discharge using Low Voltage Cutoff (LVC). Once the battery discharges to 3V per cell, the LVC will reduce the power to the motor in order to leave adequate power to the receiver and servos to land the aircraft.

When the motor power decreases, land the aircraft immediately and replace or recharge the flight battery.

Always disconnect and remove the Li-Po battery from the aircraft after each flight. Charge your Li-Po battery to about half capacity before storage. Make sure the battery charge does not fall below 3V per cell. Failure to unplug a connected battery will result in trickle discharge.

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.

NOTICE: Repeated flying to LVC will damage the battery.

ESC/Receiver Arming, Battery Installation and Center of Gravity

NOTICE: Always keep material or debris away from the intake. When armed, the rotor will turn in response to throttle movement and could ingest in any loose objects.

Arming the ESC/receiver also occurs after binding as previously described, but subsequent connection of a flight battery requires the following steps.

1. Lower the throttle and throttle trim to the lowest settings on your transmitter.
2. Remove the battery/canopy hatch from the fuselage and install a flight battery (A) all the way to the back of the battery comportment.

Center of Gravity (CG)

The CG location is 34-36mm back from the leading edge of the wing at the root. Balance the airplane inverted on this recommended CG mark with all landing gear installed. Adjust as needed by sliding the battery forward or back.

1. Power on your transmitter, then wait 5 seconds.
2. Connect the battery to the ESC, noting proper polarity. Keep the plane immobile and away from wind for 5 seconds to allow the AS3X system to initialize.

A successful connection is indicated by:

• A series of tones
• A continuous LED

CAUTION: Always disconnect the Li-Po y from the ESC when not flying to eliminate r supplied to the motor. The ESC does not an arming switch and will respond to any mitter input when a signal is present.

CAUTION: Always disconnect the Li-Po rty from the ESC when not flying to avoid discharging the battery. Batteries discharged voltage lower than the lowest approved ge may become damaged, resulting in loss of remance and potential fire when batteries charged.

Control Centering

Before the first flights, or in the event of an accident, make sure control surfaces are centered when the transmitter controls and trims are neutral. The transmitter sub-trim must be set to zero. Adjust the linkages mechanically if the control surfaces are not centered. Use of the transmitter sub-trims may not correctly center the aircraft control surfaces due to the mechanical limits of linear servos.

• Make the U-shape narrower to make the connector shorter. Make the U-shape wider to make the linkage longer.
• Ensure that the leading edge of both the horizontal stabilizers are 1mm above the lower edge of the side panel, as shown in the image to the right.

Dual Rates and Expos

To obtain the best flight performance, we recommend using a DSM2/DSMX transmitter capable of Dual Rates and Expo. Before binding, ensure that you are starting with a blank acro model in your transmitter. Set wing type and servo reversing to normal.

The suggested settings shown here are the recommended starting settings. Adjust according to the individual preferences after the initial flight.

NOTICE: Do not set your transmitter travel adjust over 100%. If the TRAVEL ADJUST is set over 100%, it will not result in more control movement, it will overdrive the servo and cause damage.

It is normal for linear servos to make significant noise. The noise is not an indication of a faulty servo.

Elevator 100%	70%	10%	0%
Rudder 100%	70%	10%	0%

Tip: For landing, we recommend using high rate elevator.

Landing Gear Removal

1. Carefully pull the gear straight out of the retainer clip that secures it into the fuselage.

When needed, assemble in reverse order.

Flying Tips and Repairs

Range Check your Radio System

After final assembly, range check the radio system with the aircraft. Refer to your specific transmitter instruction manual for range test information.

Flying

We recommend flying your aircraft outside in no greater than moderate winds or inside in a very large indoor facility. Always avoid flying near houses, trees, wires and buildings. Be careful to avoid flying in areas where there are many people, such as busy parks, schoolyards or soccer fields. Consult local laws and ordinances before choosing a location to fly your aircraft.

Hand Launching

Hold the aircraft just behind the wings. Apply full throttle with a little up elevator and give a firm toss directly into the wind with the nose pointed slightly up (5–10 degrees above the horizon). After the model gains altitude, decrease the throttle as you desire.

The A-10 has a high thrust line. If the model is not launched with enough airspeed or the throttle is added quickly at very low airspeed the aircraft will pitch down slightly. Adding some up elevator trim for the first few hand launches is recommended, until you are comfortable with the launching characteristics of this aircraft.

Tip: The electric ducted fans (EDF) acts like a jet aircraft, so control is generated by airspeed rather than air from a propeller moving over the control surfaces.

Takeoff

Taxi the aircraft in position for takeoff (facing into the wind if flying outdoors). Gradually increase the throttle to full power, holding a small amount of up elevator and steering with the rudder. Climb gently to check trim. Once the trim is adjusted, begin exploring the flight envelope of the aircraft.

Landing

Always land into the wind. Fly the landing pattern with a slightly nose high attitude. Use throttle management to control the decent rate of the aircraft.

During flare, keep the wings level and the airplane pointed into the wind. Gently lower the throttle while pulling back on the elevator to bring the aircraft down on the main wheels or to belly land without landing gear.

NOTICE: Always fully lower the throttle when landing the aircraft to prevent intake of foreign objects, which can damage the ducted fan and motor.

Failure to lower the throttle stick and trim to the lowest possible positions during a crash could result in damage to the ESC in the receiver unit, which may require replacement.

Over Current Protection (OCP)

The aircraft is equipped with Over Current Protection. OCP protects the ESC from overheating and stops the motor when the transmitter throttle is set too high and the rotor cannot turn. OCP will only activate when the throttle is positioned just above 1/2 throttle. After the ESC stops the motor, fully lower the throttle to re-arm the ESC.

Disassembly

CAUTION: DO NOT handle the rotor or motor while the flight battery is connected. Personal injury could result.

1. The lower half of the nacelle hatch is secured to the top half using glue and clear tape. Carefully cut the clear tape and follow the seam with a knife to cut the glue and remove the bottom half of the nacelle.

NOTICE: Removing tape or decals can damage paint on your aircraft. Avoid pinching or otherwise damaging any wires when opening or closing the fuselage.

1. Disconnect the motor from the receiver.
2. Carefully remove the lower half of the nacelle (A) from the upper half of the nacelle.
3. Remove the 4 screws (B) and fan unit (C) from the upper nacelle half.
4. Put a small flat blade screwdriver in the motor mount hole (D) and carefully push the rotor (E) away from the motor shaft. Rotate the rotor while prying it away from the motor (F) to avoid bending the motor shaft.
5. Remove the 4 screws (G) and motor from the motor mount.

Assembly

- Assemble in reverse order, connecting the top and bottom half of the nacelle with clear tape and or foam safe CA.

NOTICE: Always install the motor mount so that the rotor faces the front of the fuselage and the hole in the unit faces the bottom of the fuselage.
