I would highly suggest using a more modern airfoil. If you may have noticed on the plans the tip airfoil is incredibly thin and has an insane amount of washout. The Mustang was designed when we thought that you needed thin airfoils to fly fast. Having designed airfoils for a fair amount models I would be more then happy to work up a set for you, all I would need is the root cord and thickness and the tip cord.

Glad to help, this way I can do some design work without having to spend any money on a building a new airplane I don't have room for LOL. The last go fast airplane I designed for Warbird pylon racing did very well, coming within one second of the course record in Sacramento.
