It's a fairly involved build - not crazy, but maybe more than u want to tackle on a 1st bipe.

I wud suggest a Sig Hog Bipe (mine attached) if you want a easy yet satisfying project, or the Goldberg Ultimate for an all-out aerobatic machine that's still not too hard to build. The hog flies great w/ anything between a 60 2-stroke to a 91 4-stroke.
