Fast!
Take A 40 size pattern plane with A foam wing and thin the wing down and put A .60 on it and I bet it would haul butt.They are streamlined already,mybe V-tail it to.I always wanted to take A quickie and thin the wing and sweep it back,do A little work to the firewall,put A lite 45 with A pipe and see what it would do.Sound good?-Wilburn
