I was speaking with John Brodak last evening and he mentioned something I thought was interesting: with the addition of DARE, he offers over 200 kits....He is the largest kit manufacturer in the World according to a recent article.
John has built and written the construction books for each of his models, and frequently finds that the CAD pieces need to be modified to work.
A recent release of a C-130 sold out almost immediately.
John lamented that it is becoming increasingly difficult to obtain quality balsa because balsa serves as a core for wind turbine blades.
