Australian Droid + Robot Mapping Drone

This is the low cost - high performance mapping drone from Australian Droid + Robot. The Mappa uses the Pixhawk open source flight controller which has a massive community of users which lowers the cost considerably.
The Mappa is a big block of foam with wings that provides a stable, slow flying platform for crisp, blur free images. Combined with the shutter speeds of the Sony RX 100, the results are stunning.
Even if the worst happens and the Mappa is taken out of the sky by a bird, or some other event, the Mappa has a very low terminal velocity and lots of protection around the electronics. A new body is cheap.
