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 ESC.

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 recommended receiver for this aircraft is the Spektrum AR631.

If you choose to install a different receiver, it needs to be a 4-channel or more

full range (sport) receiver. Refer to the manual of your chosen receiver for

correct installation and operation instructions.

AR631 Installation

1. Press the latch button and remove the canopy.

2. Attach the appropriate control surfaces to their respective ports on the

receiver using the table at the right.

3. Using double-sided servo tape, mount the receiver to the ﬂat area behind

the ESC, as shown. The receiver 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 receiver

is critical for all AS3X

and SAFE

technology setups.

CAUTION: Incorrect installation of the receiver could cause a crash.

ANTENNA INSTALLATION

The AR631 receiver has a coaxial style antenna. We recommend installing the

antenna as far as possible from metal, batteries, or carbon ﬁber to maximize

signal reception performance.

NOTICE: Do not cut, kink, or modify the antenna. Damage to the coaxial por-

tion of an antenna will reduce the performance of the antenna. Shortening or

cutting off the 31mm tip will reduce the range.
