 I've had my Nano (BNF) for about 24 hours now but never got a chance to give it its maiden flight until this morning.... first CP heli though I'm pretty good with a single-rotor (MSR).

Using my DX6i and the program settings in the manual.  It's considerably twitchier than the MSR even with the bullet blades installed so right now I'm using all 3 dual-rates.

It seems that if I give a control input on the right stick, for example left aileron, the swashplate doesn't return to center when the stick does.  I've verified this by holding the heli down on a table with my hand and watching the swashplate, because the issue only seems to occur when the blades are spinning.

I tested stunt mode and it's really bad if I give it hard left aileron (still DR though) and release the right stick, the swashplate doesn't move back at all!  You have to go hard right just to center the swashplate.  But after cutting the throttle the swashplate behaves normally.

Needless to say this makes flying a bit challenging!

I've got it hovering reasonably stable, and in fact I didn't even have to set any trims.  But this swashplate issue is driving me bonkers.... unless this is really how CP helis are supposed to work??

If it is hovering normally, then most likely it is working properly.
This is a flybarless, 3-axis gyro system. The swash won't return to center until you command it to do so.
I have the 130x, same gyro system. It works the same way.
On the bench, if the blades are not spinning, the swash will return to level.
If the blades are spinning, the swash will stay at last commanded position.
I think I remember reading that the gyro system is not activated until the collective/throttle is advanced.
I have flown a friend's Nano, yes it is a bit twitchy, especially inside in a small space.

OK, I think that makes sense, I neglected the effect of the computer.   Since I'm holding the heli down, it's confusing the gyro system.  Since the A3X doesn't sense movement, it doesn't tell the swashplate to change from its current location because it thinks the heli is already stable.

But the reason I tested this is because of the way it behaves when flying.  Give it a bit of forward stick and it keeps going forward even after returning the right stick to center.... I'm used to the MSR being self-stabilizing in that it basically returns to a neutral hover when you let go of the right stick.  Actual my MSR will revert to its classic ''toilet bowl swirl'' but I digress.
