Peter,
just do a search for "Giant Scale Planes" and you will find tons of info on them.
Some of them like them and then others don't ! Maybe they have improved within the last 18 month ! Don't know, and probably never will, since I won't buy another one. Do you have a chance to inspect the plane before buying, or where you going to mail order the Bird Dog ?
The problem you will run into, is that there aren't many ARF's of that plane out there. Have you thought about the Goldberg Decathlon ? Now that is a very nice looking and high quality ARF (in my opinion). Flies great too ! Check it out at : http://www.carlgoldbergproducts.com/...ady_to_fly.htm
