How we do autopilot vibration-testing at 3DR labs

This is a quick demo of how we vibration-test our next-gen autopilots at 3D Robotics labs. Two big bass speakers are programmed to generate vibrations at a range of frequencies, and the autopilots are mounted on a structure that's driven by them in two dimensions. We then measure the output from the autopilots to look for aliasing and harmonics, which helps us design the…

The 'copter is a carbon…

The Coanda Effect and a cool UAV using it.

I have not seen this posted on DIY Drones yet so I thought I'd throw it out as interesting.

Somewhat safer than a quadrotor I imagine but somewhat less maneuverable.

Still interesting though :)

First flight with APM complete

I finally got around to testing out Ardupilot on a real flight. It was far too windy for a test flight and so was short and untidy. I'm now waiting for a calm day to get it tuned. I have an APM 2.5 installed in a HobbyKing Bixler 2.

There was some bad "porpoising"…
