MR210 test flight and vibration

rolandash

Well, this test flight isn't really about racing, but for setting up a micro grade airframe that can fly autonomous outdoor stably and reliably.

The key points for outdoor micro grade drone is about mag interference and vibration control. Checkout below's flight log from an MR210 frame:

The result shown by these graphs is not just good, it is amazing.
The raw acceleration graph show an extremely low vibration within only (-2 ~ 2 m/s^2).
The power spectral density graph again proved this point with mostly green area, and a clean, focused vibration band around 60Hz that can be easily filtered out by sw filter.
The FFT graph further shows vibration higher than 80Hz is almost down to 0.

The magnetic field is almost constant during flight, shows a minimum interference on mag sensor, almost idealist.
