I am currently using a Pixhawk flight controller, but I am building a 250 mini quad and would like something smaller and cheaper. I am not going to do autonomous mission and don't need a GPS, but I would like to ability to add one later.
Are there other smaller arducopter flight controllers out there? What are their disadvantages?
I am use to the APM mission planner, but what about other types of flight controllers? Are they as easy to set up and use as the Pixhawk?
