| Nice flight,
Suggest the owner/pilot to add a degree of pitch to the back rotor or take one degree away from the front to help with the tail sagging in flight.
Also letting the CG be forward of the manual suggestion helps keep that back dropping to a minimum.
Mine flys with a 1 degree difference between the front and back. Also like the XRB if you get a yaw drift in a certain direction, to balance the yaw amount or center, adjust pitch on the rotor head in question.
For example, if you have too much left drift, reduce the front pitch or increase the rear pitch depending on how it hovers, back too high or too low. The opposite holds for too much right drift, decrease rear pitch or increase front pitch.
Increase front pitch you get left yaw, increase rear pitch you get right yaw.
Then also reducing some gains on the gyro helps as well. I needed to reduce all three gains on mine as I was fighting the gyro in flight. It wanted to fly without my input. 
Also governor helps a lot.
