27. Lets install the wings at this time and check our center of
gravity (CG). Install the carbon fiber wing tube. Slide in each
wing panel and secure them with the two nylon wing retention
bolts
(figure 89).
Tip#6
If the wing tube is tight you can coat the tube with a little baby
powder to aid the insertion of the wing panels.
Now we re ready to check the CG and install your remaining hardware.

The CG range is 5 to 6 / inches back as measured where the wing meets
the fuselage (root). We recommend 5 to 6 inches for initial flights.
28. Check CG at this time and place your batteries and switches in locations to attain the desired CG. If
satisfied mount your remaining hardware.
Congratulations! You have just completed assembly of your Extra330L. Now would be a good time to apply
the optional vinyl graphics included with the kit. Make sure you apply the vinyl in a warm room and the
surface area is clean where the graphics are to be applied.
29. First, remove the backing from the clear transfer tape and place it on a clean work surface tact side
up. Apply the vinyl graphic face down on the transfer tape. Use a credit card or similar and press down
on the backing of your graphics to ensure the vinyl adheres to the transfer tape and will not lift up when
removing the paper backing
(figure 94 and 95).
30. Carefully remove the paper backing of your graphics ensuring the vinyl is adhering to the transfer
tape. Now place the transfer tape with your vinyl graphic in a location of your choice. Take your
fingers and gently rub the vinyl so it will bond firmly to the aircrafts surface
(figure 96 and 97).
31. Slowly pull the transfer tape off ensuring that the vinyl adheres to the surface
(figure 98).
