I ordered a set of the Yak - 9 plans from Brodak. If you are not in a hurry you call them to place the order they can send it out via regular mail like $3 shipping. I have done this for small orders where the standard shipping cost was more than the price of item I purchased. They also have laser cut rib sets for the Yak - 9 and some kind of templates (I didn't order the templates, don't know what they are for?).
Best, DennisT
