The Hog Bipe is a great choice after the Astro Hog. I've built 2 of each and they both fly very well. The bipe fuselage is a lot easier to build as well. The .91 four stroke is also a great match. That's what I fly on my bipe although if I ever build another the Saito 1.00 would be my choice.

The Hog Bipe is a great first bipe and won't surprise you. Just keep in mind it has a lot more drag than the monoplane so keep some power on during final approach.
