I have Hostetler plans for the Full Tilt Boogie bipe and I bought the kit from Precision Cut Kits (http://www.precisioncutkits.com/instock.html) I just looked and they have a Hostetler Skymaster kit ready to go out the door...it's big at 119" span.

The plans are excellent. My Bipe looks like it'll be a relatively straight forward build (I've not started it yet) but then I've been building for almost 40 years.

Wendell will size his plans to any size you want, the only downside being that the accessories that can be had from other sources (windshiels, cowls, etc) won't fit.

You can also try to find a Royal Skymaster kit on the auction sites.
