The Airscoot rc helicopter is one of several such mini electric rc helicopters that feature contra-rotating main rotors as opposed to the conventional single main rotor and tail rotor. Contra-rotating means that both rotors spin in opposite directions to one another.

The Airscoot's design is very beneficial to the beginner rc helicopter pilot, as the contra-rotating rotors mean that no tail rotor is needed - that's one less function to worry about!
So why no tail rotor? Well, a helicopter's tail rotor is needed to counteract the torque generated by the spinning main rotors - without a tail rotor the fuselage of the helicopter would just spin out of control in the opposite direction to the main rotors.
With the Airscoot however, each rotor balances out the torque generated by the other one and so the fuselage is not subject to the normal forces of torque. Therefore the fuselage doesn't want to spin in any direction at all.

The Airscoot rc helicopter comes ARF, with a final assembly time of around only 30 minutes.
The model comes with all mechanics and radio control servos and receiver fully installed and set up - the rc gear being a simple 4 channel system rather than the usual complicated 6 channel systems that are required to fly many model rc helicopters.
As for flying the Airscoot, it is a very stable model and can easily be flown indoors in a decent sized room. It has not been designed for helicopter aerobatics, but its intended use is to get the novice pilot used to level flight and hovering a model helicopter, both of which it does perfectly well.
Having said that though, many experienced rc helicopter pilots are finding the Airscoot rc helicopter a lot of fun to fly, particularly around the home!
The Airscoot electric rc helicopter is available from RC Discounts.
