Safety in Flying This is NOT a toy! It is a very high-performance RC airplane capable of high speeds and extreme maneuvers. It should only be operated by a competent pilot in a safe area with proper supervision. ONLY fly your aircraft in a safe, open area, away from spectators and vehicles–and where it is legal to fly. NEVER fly over an unsafe area, such as a road or street. Never fly too close to yourself or spectators. Never run your motor inside a house or building with the propeller attached – Remove the prop for safety.

Servos installation Step1. Locate the fuselage.

Step2. Locate two servos and two servo mounts. (We provide two sizes of servo mounts for 9g servo and 17g servo.)

Step3. Install the servos into the servo mounts. (You can use the self-tapping screw provided with the servo to secure the servo to the mount, or you can do this in next step.)

Step4. Use foam glue to glue the servo into the servo opening in the fuselage.

Step5. Connect a 12in servo extension into the servo lead.

Step6. Use a ruler to cut a slot for the servo lead.

Step7. Insert the servo lead into the slot.

Step4. Connect a pushrod to the control horn. (Need to enlarge the hole in the control horn.)

Step5. Use the pushrod as the guide, cut a slot on the aileron for installing the control horn.

Step6. Use foam glue to install the control horn to the aileron. (Need to cut off the excessive pushrod wire.)

Step7. With the aileron centered, tighten the screw to secure the pushrod to the servo arm.

Step8. Repeat the previous steps to install the other aileron servo and linkage.

Tail and Rudder/Elevator Servo Linkage Installation Step1.Install the servo arms to the rudder servo and elevator servo.

Step2. Locate the horizontal stabilizer, control horn and wood control horn mount.


10

Step3. Use foam glue to glue the wood mount to the elevator and install the control horn to the elevator.

Step4. Insert the horizontal tail into the slot of the fuselage. Adjust the tail to make sure it is 90 degree with the fuselage, as well make sure the distance between one point in the fuselage and left tail wing tip and the distance between that point and right tail wing tip are the same.

Step5. Apply thin CA to the area between the fuselage and tail.

Step6. Use foam glue to glue the fin together.

Step7. Glue the rudder to the fuselage. Make sure that the rudder is in the central line of the fuselage and it is perpendicular to the horizontal tail.


11

Step8. Cut a slot in the rudder for installing the control horn.

Step9. Install the rudder and elevator servo linkage using the some methods in the section of aileron servo linkage installation

Landing Gear and Tail Skid Installation Step1. Locate the items as shown.

Step2. Use two wheel collars to install the foam wheel to the landing gear wire.

Step3. Install the other foam wheel to the landing wire.


12

Step4. Locate the wood landing gear insert.

Step5. Use one M2*16mm self-tapping screw and one wood insert to secure the landing gear into the fuselage.

Step6. Locate the tail skid.

Step7. Cut a slot in the bottom of the fuselage.

Step8. Insert the tail skid into the slot and apply some thin CA to the slot.


13

Wing installation Step1. Locate four plastic hooks.

Step2. Glue them into the slots in the wings.

Step3. Locate the fiberglass wing tube and rudder bands.

Step4. Insert the wing tube into the fuselage.

Step5. Attach two wing panels onto the fuselage along the wing tube.
