Picoo Z Sky Challenger ($121) is a new and improved version of the much talked about Picoo Z R/C Helicopter.
You purchase them is paris of two and use laser beams to temporarily disable the other chopper, accompanied by a sound effect.
Only 17cms long and weighing just 11 grams, these two tiny Sky Challenger Choppers are remarkably robust, and incorporate an auto stability system to make them easy to operate both indoors and outside in calm conditions.
Supplied completely ready-to-fly with pre-installed two channel proportional wide beam infra red control systems, each lightweight Lithium Polymer flight battery will provide flights of up to 10 minutes between charges driving two powerful micro motors, yet can be recharged in less than half an hour with the portable chargers provided.
