The building part is no problem, been doing it for over 25 years.
I guess t know what "type" of Pattern I would like to fly is something I will have to decide after going to a meet and watching.
I haven't seen Pattern since the 1988 Nats in Va. Beach when my club was hosting. (Saw a nasty mid-air during practice rounds)
In those days it seemed all were fibergals fuse, foam core wings, retracts and the "new" YS engines.
