How is the Cube Purple mounted as that’s not internally isolated. Iv not checked the log yet but that stood out when you say purple on a drone ?

Unable to download log. Did you post the same on Facebook?

Yes it’s the same

In flying vehicles, please use one of the other cubes. Cube purple is for boats and cars etc…

I was aware that purple is not for flying 1 imu no isolation etc. I am trying to undarstand how pids work. Cause I had similar behavior with cube black. I had set up the same frame with a blue (same as black made in USA).It flew nicely in loiter kept it’s position nice throttle everything good but with strong wind didn’t manage it. And when I tried autotune crashed. Thanks all for replying
