Picoo Z

A tiny 2-channel IR helicopter that set a world record in 2006.

Picoo Z

The Picoo Z is a miniature remote-controlled 2-channel helicopter manufactured by Hong Kong–based Silverlit Toys. In North America it is also sold under the brand name Air Hogs Havoc Heli and distributed by Spin Master. Designed by Belgian engineer Alexander van de Rostyne, it was recognized by Guinness World Records in 2006 as the smallest remote-controlled production model helicopter in the world. Silverlit later surpassed this record in 2013 with the even smaller Nano Falcon.

Lore & Background

The Picoo Z was released in the summer of 2006. Its popularity far exceeded manufacturer and distributor expectations, causing the first shipments to sell out instantly upon arrival in stores. This demand led some resellers to offer the Picoo Z for premium prices upwards of US$150. The success quickly spawned a number of Chinese-made clones with an estimated street price of around $13 retail. Most of Silverlit's toys are manufactured in China.

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. It is designed for indoor flying but can be flown outdoors in calm conditions with minimal lighting; otherwise, sunlight can overpower the IR transmitter and cause a crash. The Picoo Z is made of tough EPP foam and contains a lithium polymer rechargeable battery and two micro motors. Charging is done by plugging the helicopter into the controller, taking 10–15 minutes for a flight duration of five to seven minutes (other sources state 5 to 10 minutes). Range is limited to up to 10 meters due to the use of infrared.

The Picoo Z features a self-stabilized main rotor with a weighted airfoil-type stabilizer bar, removing the need for corrective pilot input to achieve stable flight. It lacks collective or user-input cyclic control; the rotor blades are mounted on a simple rocking hinge with no swashplate. To achieve forward flight, the helicopter includes three stick-on weights that can be attached to the nose. Some owners add greater weight or modify the tail rotor. Without modifications, the Picoo Z can only change altitude and yaw.

Reader's Guide

The Picoo Z's significance lies in its combination of small size, low cost, and ease of use, which made it an instant hit upon its 2006 release. Its self-stabilizing rotor design allowed beginners to hover almost immediately, lowering the barrier to entry for radio-controlled helicopter flying. The use of infrared control, while limiting range and requiring indoor or low-light conditions, kept the system simple and affordable. The helicopter's popularity led to a fan base that created websites with forums, modification information, and tips, as well as fan-made videos on video sharing sites. The Picoo Z also demonstrated the market potential for ultra-miniature RC helicopters, prompting Silverlit to later release even smaller models such as the Nano Falcon. Its legacy includes a range of variations, including the Sky Challenger set that added infrared "shooting" gameplay between two helicopters. The Picoo Z remains a notable example of how a well-designed toy can achieve widespread cultural impact and spawn a community of enthusiasts.
