Announced back in 2007 by LISA Airplanes, the amazing amphibian Akoya airplane is now available for orders.  In name and design, this brilliant, private air taxi reminds us quite a bit of the Aptera, a car we reviewed on GearCrave last December.  Powered by a tail-mounted 100hp Rotax piston engine and made of high-tech composite materials, this Akoya is able to operate from either land, snow or water.  Orders will be accepted for around $400,000, with an initial $13,000 advance, although the delivery date will not be guaranteed.
