I also hear the Skybolt was easy to build.....what a bunch of hooey. It's not as easy as a 4star but I had no problems at all. The directions were easy to follow and very detailed. The hardest part was trying decide on the color scheme. Build the Slybolt if you like to hear oooo's and ahhhh's when you get to the field. The Hog bipe is nice too but get the fiberglass cowl that Stan's Fibertech makes for it. That open motor just ruins the whole look[:'(]
