I built this kit this past summer. The instructions do not give the CG in measurable units. The plans indicate the CG as being just a little forward of the rear corner of the center wing strut. Basically put your finger in that corner and see if the plane will sit level without fuel. I have found that the kit comes out a little nose heavy with all standard ball bearing servos and a 46fx engine. To get the plane's CG back a little and to lighten the overall weight, I removed the wheel pants.

This is a really fun plane to fly, its not a great 3d trainer but very aerobatic. You will love it.
