This past weekend I updated the Ardupilot firmware to version 2.9.1 on my small quad. It is a DJI 450 frame with the APM 2.0 board and went out to a local park to give it a spin. Wow! My first reaction is that it flew remarkably well! I haven’t been flying the Ardupilot much lately because my other NAZA equipped copters are such a joy to fly. Maybe it’s time to have a second look at the APM.

I didn’t shoot any video of the flights… But here is a quick cellphone photo of the setup.
