You put a link to the 1/4 Scale Citabria Pro, That's not a bipe, It is a aerobatic high wing, 2 of my flying friends and I are planning to build Hog bipes this winter, From the research I've read there are tons of modifications that can be done to the Hog to make it look better and it is supposed to be a great flying plane too. Could this be the one you where looking at at Balsausa http://www.balsausa.com/kits/kit.htp?id=33&shopperid=
