But understand it's limitation... You said your a excellent builder and

your cost down and still have a safe plane, as long as you fly within it's
envelope... And on Club members.... If you fly within you and your plane's
envelope.... And are truely haveing a hard time $$$$$ wise in this hobby
some members will help in keeping you going......
