I have made three astro hogs and one hog pipe. They are great planes to build and fly. I consider Sig kits the best on the market in terms of quality, plans, and instructions.

A recommendation I would give you is to cover the wing tips with 1/16 to 1/32" balsa. Also, put foam in the tips to give the balsa support. I have done this on every hog I have built. This technique has protected the wings from minor damage and really doesn't add much weight. It also makes the wing look better.
