I am a plans junkie, and have been all over the web looking for free plans.
I will not use any that have been posted as scans from RCM, etc. If I want that aircraft, I'll get a better deal by purchasing from the designer or plan holder.
I am guilty of scanning someones 3-views so I can trace them for conversion to buildable plans.
Most plans are under $30 & its well sorth it to get good copies.
