Richard Outred has kindly dropped us an email regarding the Epson µFR-II micro-helicopter, and pointed us to a smaller one, the Pixelito which has been around for some months. It doesn’t have the same bluetooth support, but it’s lighter. The page gives some details on how the device was created, and points to the reduction in battery size in a factor for reducing the size of his designs over the year. We’d like to see the hamster in a flight outfit though.
Thanks for the tip Richard.
