Cheapest i've seen a mini helicopter so far.
Probably the smallest helicopter in the world! The Wasp RC is only six inches long and weighing an incredible 10 grams, the amazing new Wasp micro helicopter is a fascinating flying machine that is super stable and easy to fly in the smallest of spaces, and unbelievably fits in the palm of your hand for fantastic desk top fun! The Wasp Micro Helicopter is supplied completely ready-to-fly with an innovative pre-installed two channel proportional wide beam infra red control system, the lightweight Lithium Polymer flight battery will provide flights of 10 minutes or more between charges driving two powerful micro motors, yet can be recharged in less than half an hour with the portable charger provided. The helicopter has a small blue LED strobe light that flashes when in-flight for night flying
