I just checked the plans in my kit. The CG range is 4 7/8" - 5 7/8" behind the leading edge of the top wing at the center section. With everyone talking about the weight of the finished model, this thing sounds like a prime candidate for an Irvine .53 or maybe even a .60. Hmm, I still have a couple of YS .60 short strokes sitting in the drawer. I bet they would make the Tecate perform!
