These have been available for over a year. I won one in a raffle at last years SIG C/L fun fly, which is coming up again this weekend. I had ideas of having it built to take back this year but it's still in the box. This kit and the smaller Wee Duper Zilch were mostly the work of Bob Nelson. SIG was/is the last holder of the rights to Berkeley kits.
Type at you later,
