IMHO the best bipe out there for general all around flying, and for being an easy bipe to start out on, is the Sig Hog Bipe. I've had 3 Sig Pigs and I love them. They are a lot more forgiving than most other bipes, but still fly like a bipe. They look great. And they are an easy building plane. This plane seems like it was made for a 91 4-stroke engine. You won't be worry here for getting one.

Hope this helps
