Don't get me started with the Cub thing. I can give you the three primary reasons why that plane is bursting from the seams from every RC magazine.

#1 It does have value as a scale design goes. People who learned to fly real planes trained in a Cub. So it makes sence that what you learned to get your Pilots license with, suddenly becomes appealing as a kit.

#2 Of all the documentation available for the Piper Cub. Very detailed material is available to build a kit from. In fact, Piper released very sharp and large plan views of the plane, in such a way, that it was almost drawn up for direct use as a scale kit. Almost no work has to be done for any company who wants to produce a Cub kit.

#3 The design is so basic, it's almost looks like Piper made the real plane by copying a model kit.

For companies like us, we have to almost purchase the full size plane to make an accurate kit. Specially with aircraft that is still in production.
