Transmitter Setup

IMPORTANT: The installed receiver has been programmed for operation speciﬁ cally in this aircraft.

To operate the SAFE® system in this aircraft, set up your optional DSM2®/DSMX® transmitter using the chart below.

- SAFE Flight mode is selected using Channel 5 signal (high, middle, low)

- Panic Recovery mode is selected with Channel 6 signal (high, low)

IMPORTANT: A transmitter with a 2-position Channel 5 switch will only allow the use of position 0 or position 2 ﬂ ight modes. If possible assign Channel 5 in your transmitter to a 3-position switch to operate all 3 ﬂ ight modes (refer to your transmitter manual).

SAFE® Technology Flight Modes

Beginner Mode (with Self leveling):

Pitch (nose up and down) and Roll (wing tips up and down) angles are limited to help you keep the aircraft airborne. Release both sticks for self-leveling.

Intermediate Mode:

The pilot is only prevented from entering extreme ﬂ ight conditions.

Beginner Mode

(Switch Position 0)

Intermediate Mode (Switch Position 1)

RollPitch

Experienced Mode:

Unlimited Flight Envelope

Panic Recovery Mode:

If you feel you have lost control in any mode, hold the Panic Recovery trigger. The SAFE technology will return the aircraft to a stable attitude (wings level with a slight climb). Always ﬂ y at a safe altitude, as Panic Recovery may cause the aircraft to lose some altitude when leveling the wings. Release the Panic Recovery trigger to turn off Panic mode and return to the current SAFE ﬁ ght mode.

Experienced Mode (Switch Position 2)

NOTICE: If the aircraft is upside down when the Panic

Recovery trigger is pressed, sufﬁ cient altitude is required

for the aircraft to return to straight and level ﬂ ight.

Installing Landing Gear

1. Insert the main landing gear assemblies into the plastic brackets on the bottom of the wing with the

struts toward the front of the wing.

2. Ensure the landing gear wires are fully inserted

into the clip so the end of the wire snaps into place.

3. Insert the nose gear into the plastic nose gear mount on the bottom of the fuselage.
