I just finished building my first TH plane the other day, the Edge, and am about 75% done with building the CY. I used both the Edge instructions and the build info here, and choose to do my own thing with a few aspects.
The CY goes together really easy. The high you can get from Welders is a plus. A nice touch is the servo areas are already cut-to-size for the TH kit servos - sweet! Lasers cut foam nicer than I do.
Hella nice job on the CY, guys. Gonna maiden the Edge in the next day or so, then the CY. Fun times in 2012 and it's only January.
