Mini APN (newbee)

mini APM v3.1

Hi there I was wondering if to set this up, in H mode or x mode as at the moment it is setup x mode also flying in the front Room at the moment but seems unstable I have not carried out auto trim or auto tune yet just in case it has to be in H configaration. I have flashed firmware to x configaration. But when detecting board saying 2560v2 then saying board has retired so will flash firmware compatable to mini Apn v3.1
as thought it would now the board was a APN v3.1 it is flying but have to keep puting continual stick inputs in to keep correcting it, have now done a trim calabration, setup compass and gyro calibration. But seems unstable.

Any help please
