I've only built a hand full of kits, so you'll have to take my opinions with a grain of salt. The Hog Bipe is not difficult to build. I don't think I'd recomend it as a first kit though. With two wings and getting the wings aligned, there's a fair bit that can be messed up. The directions are also not quite as explicit as say, the directions for a trainer... with the Hog Bipe, it seems they expect you to know which glue to use where and so on.

As to how it flies...well, I've had a few flights on mine(currently waiting for a wing kit[:@] ) and it is defintely a step or two up from a trainer. Quick roll rate, doesn't glide as well as a trainer does, turns better with some rudder, lands nice and slow.

If this your first kit build or you're just moving up from a trainer, I'd say maybe try something else first. I know I would not have been comfortable flying it as my second airplane or it as a first kit to build.... however as they say, individual results may vary!
