build your own multiwii based drone. you'll get a more complete understanding of the hardware and software this way: https://nathan.vertile.com/blog/2016/04/24/rctimer-u210-mini-quad-build-setup-and-review/ https://nathan.vertile.com/blog/2016/04/24/rctimer-u210-mini... then for firmware, there are 3 modern forks of multiwii: cleanflight, betaflight and inav. if you want gps navigation, put iNav on it: https://github.com/iNavFlight/inav/ https://github.com/iNavFlight/inav/ if you want awesome flight performance, use betaflight there is also a slightly more robust autopilot firmware, dronin (which is an openpilot continuation) which can run on the flight controller listed on that blog post: https://github.com/d-ronin/dronin/issues/9 https://github.com/d-ronin/dronin/issues/9 full disclosure, that's my blog :)
