Question: Where is the CG located on the VMAR Extra 330L 45-60 ARF ECS?

Answer: In stage 29 on page 15 of the manual there is a diagram and information as follows: The CG is located 4.75-5.25 inches (120-130 mm) back from the leading edge of the wing. This information is correct.

Additional Information: This is an aerobatic model. It is designed for aerobatics and is inherently less stable than a high wing trainer. The CG location affects its ability to do aerobatics. Setting the CG further forward will make the model more stable (easier to fly) but will limit it's ability to do aerobatics. Flyers who are unfamiliar with flying an Extra 330L OR who wish to test the model initially in a more stable configuration may wish to move the CG further forward for the first few flights. The CG can be moved ahead to lie up to 1/2" (12 mm) forward of the thickest part of the wing. This will be a more stable less aerobatically capable configuration. After becoming confident and more familiar with the flying characteristics the CG can be moved further aft towards the recommended location.
