A team of people who had worked at Joby Robotics, who were doing the UAV-as-energy-generating-kite thing we wrote about earlier (which I gather didn't work out, sadly), is trying to raise money on Kickstarter to turn their hybrid quad-plane aircraft into a commercial product.
The Quadshot is a remote-controlled aircraft we have created that melds advanced Open-Source hardware and software with a unique airframe design. It can both fly forward like an airplane and hover like a helicopter - but without the usual complicated, expensive, and fragile moving parts.
It uses the Lisa Paparazzi IMU, but isn't meant to be a UAV. Instead, the electronics serve as a pilot assist, and you can switch from copter to plane to acrobatic combo with a flick of a RC switch. $500 to pre-order the version with the IMU.
