The Bridi Krafty 60 (semi symmetrical) has been "currently out of stock" for a year and a half from Bluejay. I inquired as to an expected date they would be available, never got a reply. Makes one wonder if they are going to continue producing. Eureka offers a kit of the Bridi RCM Trainer (not sure of airfoil).
The Bridi Trainer has many vesions, with differences in airfoil, wingspan and the tail.
The Great Planes version that JollyPopper speaks of was offered by GP in the 80's, has a symmetrical airfoil and a 2 piece (split) elevator. It was offered in .20, .40, & .60 sizes.
Plans for any of the versions can be obtained from various sources.
