If you go into the kit building forum there is a sticky at the top, Where have all the kits gone. People have been posting there for about a year. Go onto Towers site and look at what few kits they have there. For old school pattern planes I go to Blue Jay because I'm a fan of Joe Bridi designs but these are builders kits and not something for new builders. Great Planes and SIG instructions are much easier to follow and have photos taking the builder through each step. At Tower take a look at the Ultra Sport, it's the grand son of Bridis Kaos. If you look around you may find one of the old GP Decathlon kits, pretty much the same thing as the Citabria. RCU also has a forum of items for sale and there are often some nice kits there. If you are a good builder then you can buy plans for almost any type of plane. Model Airplane News plans section, RC Modeler Plans section, the AMA web site plans section. For plans building I get my wood from Lone Star Balsa or Balsa USA in bulk.
