Here's a hypothetical. What if the BOM rule went away and some of the top
competitors began selling components? Treger sells his hub for about $100.
 Let's say Schramm started selling wings for $150, and prop blades for $100
a pair. Now you need to spend $350 to build one plane. You need several
backup models to compete. That means I need to invest $1400 in models to be
competitive. Is that going to spur interest in the hobby or will it just
scare away the average guy like myself that can't afford to risk a $350
model on every flight?
