The Hobbico Avistar also has a semi symmetrical wing. They are quite well thought of at my club. I believe the new NexStar also has a semi symmetrical wing, but I have not seen these fly.

My son did a beautiful barrel roll today with his Avistar. Quickly followed by Mr. Instructor "I'm taking control now......." Santa brought the Avistar because it was seen being very well flown in a demo before Christmas. I'm really not qualified to say it's a great aerobatic plane but it looks good to me!
