I really wish manufacturers would stand on their (legitimate) merits and refrain from marketing BS such as this:
large R-Cs need carbon fiber tubes, quartz mirrors, and cooling fans

Oh really....? How many professional institutions (that collectively) spend millions of dollars analysing mechanical merit functions opt for RC's which are constructed using quartz mirrors and something other than a welded steel truss?

Cue; tumble weed emoticon.
