As has been said already here, Dodgson Designs is no longer in business.
But, it is possible to find a kit every now and then here on RCU, eBay, and other places.
Just ask around online and search eBay if you are looking for a particular plane.
But, be forewarned!! I have seen some Dodgson planes go for ridiculous amounts of money on eBay!(of course,so do other items there!)
Sure do wish someone(Hey Shawn!) would bring back some of the Dodgson kits--with maybe a little "updating".
