Have a look at this video.
I find it very helpful when I was setting up mine.

In normal flight you trim it by changing the swash link lengths.

In that case, take Stan's advice!

The best thing to do is plug it in, into software and if you have a swash leveller, Pull the head and at mid stick get the horns to 90 degrees and then adjust linkages to level the swash at mid stick.

if it is mechanically set you should have a very stable Heli.

If the swash is level the drift will most certainly be due to vibration. Check every single screw, boom support, fins..... Everything.

then take blades of and gently spool up on the bench. Watch the swash and if it starts moving come back to us here. Try figure out your headspeed from your position of the stick if you have a straight curve, this will help narrow a vibration down.

On the assumption that the swash was level to begin with, changing the swash link lengths would push it out from true woudln't it !?

Fully agree with you!

Yes, if swash is true at mid stick mechanically then change nothing. I would put money that this is a vibe. I had a T500 that was perfect ramping up to half stick then when going light on skids would tip left and back very fast.

it was the rubber canopy stand off on left side that was loose and giving a vibe at that particular point which caused the tip.

After I sorted that I had a back and left drift, this was the carbon boom stay vibrating, I put some thin gasket between the metal stay end and the frame, all good, rock solid now.
