This past winter I built a sport 19 profile using a left over Bi-Slob wing, I just got back from the park and I have to say this is the best flying sport plane I've ever designed and built! A nice fat wing with lots of wing area and only weighs 23 oz. ready to fly, On 54' foot lines this plane will do most anything you want and sould do the AMA pattern with no problems. If you go to my site click on photos there is a album with the numbers for it, so if you have a left over Bi-Slob wing give this one a try you won't be dissapointed.
Thanks
