Picoo Z


The Picoo Z (also sold under the brand name of Air Hogs Havoc Heli in North America) is a miniature remote-controlled 2-channel helicopter manufactured by Hong Kong-based Silverlit Toys. In the United States it is distributed by Spin Master.

Designed by the Belgian engineer Alexander van de Rostyne, the Picoo Z was the smallest remote-controlled production model helicopter in the world (Guinness World Records) in 2006. However, Silverlit beats their own record again in 2013 with an even smaller RC helicopter-Nano Falcon

Weighing a mere 10 grams, the Picoo Z measures 170mm long, and has a main rotor span of 130mm. The helicopter is controlled by a 3-frequency a-b-c infrared controller, with two channels (one for the main rotor and one for the tail rotor) allowing independent user control of throttle (main rotor RPM) and tail rotor RPM. It is designed for indoor flying, but can also be flown outdoors in calm conditions with minimal lighting, otherwise the sun will overpower the IR transmitter and cause the Picoo Z to crash. The Picoo Z is made of tough EPP (expanded polypropylene) foam and comprises a lithium polymer rechargeable battery and 2 micro motors. The helicopter is recharged by plugging it into the controller. Charging generally takes 10–15 minutes and will give the Picoo Z a flight duration anywhere between 5 and 7 minutes. Range is limited due to the use of infrared instead of the more common radio frequency remote control. Because of this, ambient light may also have varying degrees of effect on the range and responsiveness of the helicopter. MSRP is between $20 and $40 USD.

The Picoo Z features a self-stabilized main rotor with a weighted airfoil-type stabilizer bar that removes the need for corrective pilot input to achieve stable flight. Because of this full-cyclic-authority stabilizer design, merely applying enough lift power to cancel gravity allows the Picoo Z to hover almost immediately making it very simplistic for a beginner.
