PID looptime: why it is not only about frequency
Last 18 months was an extremely good period of time for all mini-quad enthusiasts. Progress, hardware and software both, was just incredible. Who could have guessed that in less than 2 years mini-quads will evolve into main group of drones with such excellent flight characteristics. Just take a look at looptime. When I entered the…
