My Hexacopter vibrates after I give short stroke with pitch and roll stick.
It doesn’t vibrates when I push control stick either pitch and roll.
I did autotune several times, but it didn’t work with that vibration.
How can i control it?
Read the tuning ardupilot page: http://ardupilot.org/copter/docs/tuning.html?highlight=tune and post any question that you have here.
And when you post your questions after reading the Wiki, as @amilcarlucas suggested, please include a .bin file from the flight controller of the flight.
Otherwise its just guessing what is wrong.
