Gaui 330X Build Guide

The Gaui 330X-S UAVs are supplied in kit form with all components required to complete the build (apart from the radio gear and battery). The assembly is not difficult if you take your time and check the instructions carefully. This guide will show you step-by-step how to complete the 330XS. It is designed as an illustrated reference - we recommended that you closely follow the Gaui manual throughout the assembly process.

Tools needed: CA glue, size 0 screwdriver, size 1.5 allen key, thread lock, small nose pliers, scissors.

1. Insert the magnet into the hole of each windshield mount. Use CA to glue it on the underside.

2. Assemble the landing gear as shown above.

3. The assembled gear components should look like this.

4. Begin assembling the pieces of the frame. Use thread lock on screws. IMPORTANT: Ensure the motor mount plate is correctly aligned - with the mounting holes in the positions shown.

The correct positioning shown from a different angle.

5. Ensure the screws are tightened on each section

6. Carefully CA glue the inner joints of the sides and top plate. Only a small amount is needed for a secure join.

7. Assemble the aluminium posts (8 pieces) to the centre frame as shown.

8. Attach using the M2x4.6mm screws.

9. Slot the four frame extensions into the top half of the centre frame.

10. Then attach the bottom plate to the main assembly. IMPORTANT: You must ensure that the hole pattern of the top plate matches that of the bottom plate. Note the larger holes along one edge of the two plates.

11. Once positioned correctly, fix to the aluminium poles with the remaining M2x4.6mm screws

12. Use a small amount of CA glue on the upper join between the frame and the motor arm. NOTE: We advise not to glue the bottom plate as this may need to be removed to allow maintenance of other components.

13. Insert each ESC through the frame, as shown. Feed the signal plug through the upper hole...

and the power plug out of the bottom hole.

14. Install each motor using the M3x3 screws.

15. Connect the motor wires to the ESCs. IMPORTANT: Take care to ease these together without bending or using excessive force, otherwise you may break the connector pin. Also...

make sure that the connections for motor 2 and 4 (as per the instruction manual) are reversed for the black and red wires.

16. Feed the 4-in-1 power connector through the right side of the frame and out of the top hole...

then connect them up...

and feed them back through the hole.

17. Apply the Velcro strip (cut to 7.5cm length) across the lower panel.

18. Take four squares of double sided foam (only use the ones included in the kit) and stick to the bottom corners of the GU-344 gyro.

19. Attach the gyro in the position shown and insert each ESC signal plug correctly (as shown in the manual). IMPORTANT: the arrow on the GU-344 nameplate should be towards the nose direction

20. Insert the signal plugs from the GU-344 to the receiver correctly (as shown in the manual). Then attach the receiver to the frame with double-sided tape in the position shown. Tip: use a small tie-wrap to keep the wires tidy.

21. Assemble the props, adaptors and spinners as above, Ensure the 'GAUI' logo is facing upward on the prop...

22. and they are positioned correctly for the direction of rotation as show above. Fix the adapter to the motor shaft using the M3X3 allen screw. Tighten the spinner using a small spanner.

23. Carefully trim the windshield along the raised edge of the circumference using small scissors.

24. CA glue the metal washers in the positions shown and allow to dry.

25. The windshield is then simply held in place by the four magnets.

26. Push the white plastic tube through the outer hole of the frame below motor 4...

then insert the orange ball onto the middle of the tube (CA glue in place) and push the other end of the tube through the hole below motor 1.

27. The battery can be attached after applying the other piece of 7.5 cm Velcro to its bottom surface.
