Transmitter Setup

Dual Rates

To obtain the best fl ight performance, we
recommend using a DSM2/DSMX radio capable
of adjustable Dual Rates. The suggested settings
shown here are the recommended starting settings.
Adjust according to the individual preferences after
the initial fl ight.

Dual Rate

High Low

Elevator 100% 70%

Rudder 100% 70%

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 signifi cant
noise. The noise is not an indication of a
faulty servo.

Wing Installation

Install the wing on the fuselage using 4 screws.

Tip: For the fi rst fl ight, fl y the model in low rate.

Transmitter and Receiver Binding

EN

Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifi er)
code of a single specifi c transmitter. You need to ‘bind’ your chosen Spektrum
equipped aircraft transmitter to the receiver for proper operation.

Any full range Spektrum DSM2/DSMX transmitter can bind to the DSM2/DSMX receiver. Please visit www.
bindnfl y.com for a complete list of compatible transmitters.

Binding Procedure

9

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 fl ight battery is disconnected from the aircraft.

3. Power off your transmitter.

4. Connect the fl ight battery in the aircraft. The receiver LED will begin to fl ash rapidly (typically after
5 seconds).

5. Make sure the transmitter controls are neutral and the throttle and throttle trim are in low position.

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.
