Assembly Instructions

1. Cut off the connections (shown blue in the picture) and remove the parts.
2. Use utility knife to cut carbon rods.
3. Divide φ0.8mm carbon rod into: 2x 425mm; 2x 300mm; 1x 117mm; 1x 38mm；1x 31mm.

4. Use 502 glue to attach the φ0.8mm carbon rod to the fuselage frame.
5.
6. Insert a φ1.5mm x 250mm carbon rod into the fuselage and glue it with 502 glue.

7. Install part I.
Note: Place the fuselage on a level surface to ensure part I level. The slots are facing the tail.
8. Assemble the landing gear. Use heat-shrinkable tube to hold the wheels.
9. Combined motor unit. Note: Only the non-skid end of the shaft can be put into the
copper bushing, otherwise it will be stuck.

10. Use glue to bond copper bushing.
11. Install landing gear and battery seat (E), servo seat (L).
In case of resistance, slightly polish the clamp. Temporarily not bonded.
12. Take two φ0.8x300mm carbon rods, combine with part C, and fix with 502 glue.

13. Bend the carbon into tail frame; The end of the carbon rod is extended by 10 mm.
Note: The direction of carbon rod bending is confusing. Please observe the picture.
14. The carbon rod end stopper (part G) has a gap of 4-5 mm between the stopper and the
bracket. (Please read step 13 before bonding)
15. The root of the tail fin needs to be inserted into the groove of part I, and it can rotate
freely without sticking. Excess carbon rods are removed at the end.

16. Use the screws to secure part H to form a full-motion V-tail.
17. Two φ0.8x425mm carbon rods were taken and combined with Part B to form a wing.
Both ends of the carbon rod are 80 mm apart from part B.
18. Use heat-shrink tube to connect the wings on both sides and glue with 502 glue.

19.
20.
21. Use part D to secure the wing.

22.
23. Six propeller adapters (K) have different diameters. Please choose the optimum size
according to the propeller aperture.
24. The propeller adapter is wedge-shaped and is installed with the smaller end facing
forward.

25.Install the propeller.
26.Install the servos. Use Velcro to attach the battery and receiver.
Adjust the center of gravity to 40mm back from the leading edge of wing, glue the
mounting base.
27. Use heat-shrinkable tube to connect the φ1mm carbon rod to the clips.
Note: The length of the push rods needs to be cut according to the actual demand.
