That's baffling. Engineering is the art of compromise. The helicopter _does_ have many compromises in it's design, but it's benefits are unmatched by other aerial vehicles. In other words, the benefits outweigh the negatives.

If you don't believe me, go to your nearest general aviation airport, hire a training helicopter and an instructor, and try it yourself.

Other Pilots have already commented - it is nowhere as difficult as balancing on a Basketball.
