Preﬂ ight

1 Remove and inspect contents. 2 Read this instruction manual thoroughly. 3 Charge the ﬂ ight battery. 4 Setup Transmitter using transmitter setup chart. 5 Fully assemble the airplane. 6 Install the ﬂ ight battery in the aircraft (once it has been fully charged). 7 Check the Center of Gravity (CG). 8 Bind the aircraft to your transmitter. 9 Make sure linkages move freely.

Transmitter Setup

IMPORTANT: After you set up your model, always rebind the transmitter and

receiver to set the desired failsafe positions.

Dual Rates

Take ﬁ rst ﬂ ights in Low Rate. For landings, use high rate elevator.

NOTICE: To ensure AS3X functions properly, do not lower rate values below

50%. If lower rates are desired, manually adjust the position of the pushrods on the servo arm.

NOTICE: If oscillation occurs at high speed, refer to the Troubleshooting Guide for more information.

Expo

Expo is factory set in the receiver. After ﬁ rst ﬂ ights, you may adjust expo in your transmitter or refer to the AR636 receiver manual for expo adjustment.

10 Test the retract operation. 11 Test the ﬂ ap operation. 12 Perform the Control Direction Test with the transmitter. 13 Perform the AS3X Control Direction Test with the aircraft. 14 Adjust ﬂ ight controls and transmitter. 15 Perform a radio system Range Test. 16 Find a safe open area to ﬂ y. 17 Plan ﬂ ight for ﬂ ying ﬁ eld conditions.

Model Assembly

Horizontal Tail Installation

1. Slide the horizontal tail tube (A) into the hole in the rear of the fuselage.

2. Install the 2 piece (left and right) horizontal tail as shown. Ensure the control horn faces down.

3. Secure the two horizontal tail pieces in place using the 2 included screws.

4. Attach the clevis to the elevator control horn (see instructions for clevis connection).

Model Assembly Continued

Wing Installation

1. Remove the canopy hatch.

2. Guide the Flaps, Retracts and Aileron servo connectors (A) through the hole (B) located in the bottom of the fuselage as shown.

Tip: If needed, use hemostats or pliers to pull the servo connectors into the fuselage.

3. Connect the Flaps, Retracts and Aileron connectors to respective Y-harnesses connected to the receiver. The left and right servos can be connected to either side of a Y-harness.

IMPORTANT: The ailerons must be connected to the receiver’s AILE (#2 channel) with a Y-harness (included) for the AS3X

4. Align the wing with the fuselage and secure into position using the included 4 screws (C).

CAUTION: DO NOT crush or otherwise damage the wiring when

attaching the wing to the fuselage.

5. Reinstall the canopy hatch on the fuselage.

Disassemble in reverse order.

Clevis Installation

• Pull the tube from the clevis to the linkage.

• Carefully spread the clevis, then insert the clevis pin into the desired hole in

the control horn.

• Move the tube to hold the clevis on the control horn.

Control Surface Centering

After assembly and transmitter setup, conﬁ rm that the control surfaces are centered. If the control surfaces are not centered, mechanically center the control surfaces by adjusting the linkages.

If adjustment is required, turn the clevis on the linkage to change the length of the linkage between the servo arm and the control horn.

After binding a transmitter to the aircraft receiver, set the trims and sub-trims to 0, then adjust the clevises to center the control surfaces.
