Looking to hire a expert for faster advise as time is of great value right now.
Using

Quad copter

Few of the dev from ardupilot are helping me but obviously the replies takes time and we losing out on time.

Dm me if anyone interested.

More details on our progress wit the help of dev since 25 Days - 20kg payload quad copter Auto Tune Results- advise changes

I think @Leonardthall is offering professional tuning,

This is a paid service he runs commercially so it wouldn’t be free, but it would generate great results!
