3 days of work and trial and error, but I'm at a total loss here :

So i managed to fix an odd rolling issue i had (whenever i'd yaw or roll, the heli would ragdoll around all weird in the air.)

Got that resolved, no longer happens - that i'm aware of. But now, i got a weird leaning issue when i'm hovering,
which pulls my heli off to the left, correcting it with trim doesn't really help seeing as how that interferes with flight.
I've double checked that my center of mass is basically as close as i can get it to directly beneath the main rotor,
my fuel tanks are below the main rotor.

But now, when i fly in a straight line, the heli pulls to the right/left ever so slightly when in motion,
and when at a standstill, it sags back and to the left, pulling it off course.

I honestly don't know what the issue is, i could use a fresh set of eyes.
If someone could take a peek, maybe you can find what's causing it, cause i'm fresh out of ideas.
I'll provide the link here to the helicopter, if you do manage to find or fix the issue
if you could post a link and i'll give co-author credit.

Thanks for any potential help with this issue.
