Parrot looks like good options. Cost is little bit high since I am only doing it as a project but can be managed. I checked that parrot supports open source platform dronecode (http://diydrones.com/profiles/blogs/parrot-team-blacksheep-walkera-and-others-join-dronecode http://diydrones.com/profiles/blogs/parrot-team-blacksheep-w...). Is it rival to ardupilot? Is there some good place where I can read about material regarding drones? Hardware as well as software? Since drones are in relatively early stage of adoption, there is lot of noise in hardware as well as software for drones (multiple specifications/platforms) and becomes little hard to choose one of them.
