Honestly I never understood why anyone would do this. R/C Modelers
always claim they "can't afford to fly the real thing" so they settle
for models, but they spend more in modeling than it costs to fly real
gliders.
I spent about $3000.00 flying r/c helicopters... but it only cost me
$2500.00 to learn to fly real gliders, and my check ride should be any
time now

And I bet that 1/2 scale glider costs more than a Ka6.
