Why does my aircraft roll when i pitch up even though it's symmetrical?

@MyanMORPOWA wdym

@Boredplanet What is your Pitch?

@MyanMORPOWA i used mirror

@MyanMORPOWA Or your control are off? Like I said without anymore information given I don't know anything else.

Well without anymore information all I can say is either your Center of Mass(CoM) is off balance which means you didn't use mirror.

@Boredplanet
I would post this one too so someone can comb over it.
We could guess at many things and be wrong but just spending a few minutes with it I could find out whats causing the drag to make it roll.
In saying that. I wont be home to test it for a couple days. Gone for the weekend.

More information is needed. If you'd like, I can test it and diagnose.
