A small helicopter is a great indoor toy,
because they are not likely to harm furnishings or pets. The
Syma S107, and the Helizone Firebird sister ship, are examples
of the high quality you can find in them
A 3 channel IR helicopter has a simple control:
it hovers in place automatically. When you push forward, the
tail rotor spins to push air DOWN. This LIFTS the TAIL, and
the copter "slides" forward on its air column. turning left or
right allows you to avoid objects.

The futuristic look of the helicopter canopy really makes the
copter look purposeful.
