Allowing purchased hubs devalues the time and effort myself and countless
others have invested learning the skills necessary to build one. Should we
also allow other "hard to build" components to be purchased? Maybe someone
can start selling motor tubes and tail booms so the only skill required to
build an F1D is knowing how to glue sticks together.

Why can't some things in life be a challenge? It saddens me that this
conversation is even happening.
