Well by old school...Im guessing you mean planes like the Kwik Fly, Flea Fly, Daddy Rabbit, etc. None of which fly worth a flip. Overweight rocketships with not enough wing area or rudder for today's aerobatics.

Here are plans for many of the old vintage planes

One suggestion. if you go with the KwikFly - change the flat stab out for a airfoiled or diamond shaped stab. It will fly MUCH better.
My dad loves these things.

Honestly, bear in mind that NONE of them will fly as well as a more modern pattern design. If your doing it specifically because you want a vintage plane...go for it, but dont expect it to fly like your buddies brio.
