When the fuel tank is attached (mass scale and capacity modded) the inboard ailerons and rudder rotators will continue to flutter after being moved. For some reason the other ailerons and elevators aren't affected. Everything moves as usual when the tank is removed.
The plane (moved fuel tank into view, flies normally at the moment when buried in the fuselage for balance):

Also, is there any meaning to the drag points number? I just made it similar to other builds but it'd be nice to know how to get it as accurate as possible.
@XxRxX welp it appears that the presence of fuel is causing it
sorry idk why they shake like this
I set the mass scale to 0 and they still act as if they have mass.
Let me download it see if I can help
And yes drag is how much your build will resist against wind or air when it moves
I think anything around 1000 or 2000 is realistic for a plane or a fighter
