Sam San is now concentrating on his composite kit business.
Here is one of his Semi-Composite-Kits. His products fly great and are available at competitive prices.
Here's a link to this kit:
The composite versions are legal for the 426 class racer. They are not legal for 424 (Thunder Tiger) racing.
The wing weighs in at 16.75 ounces and modelers should have no problem building a racer at minimum weight.
I plan on finishing a couple other models before getting started on this one.
