It doesn't do much?
Today, I had the opportunity to watch someone really fly a heli and so did the large crowed that stopped what they were doing to watch it.
My personal thought is that planes are cool and difficult but you can only do loops so many times. A car goes around the track does some jumps and if you have a really nice street car you can do 70mph going straight.
A small (30) heli will do all that a plane does and much much more and it can go somewhere around 60 mph
The larger helis can go 85-90 mph.
