Trying to write a MM Patch to reduce Drag of Panel Flags. How to address the specific part variants?

[HB Stratos]

As the title says, I am trying to write a MM Patch that reduces the drag of the panel variant of the stock Flags. Their drag is simply ridiculous, almost rivalling a parachute. 

I have a patch that can successfully address all Flag Configs, but I cannot figure out how to affect the drag cube of the panel flags. They are part variants of the Flag of course, but their configs do not specify a change in drag cube, yet the behavior in game between a thin flag (no drag) and a panel flag (a lot of drag) is wildly different. 

Here's my MM patch. It works in that all requested changes are applied, but none of them actually change the drag behavior of the flags. How do I fix this?

//@PART[flagPart*]
{
	@maximum_drag = 0.01

	@MODULE[ModulePartVariants]
	{
		@useMultipleDragCubes = true

		@VARIANT[*Panel]
		{
			@sizeGroup = nonStructural
			@attachRules = 0,1,0,0,1
		}
	}	
}

Honestly it would be nice if flags were just physics-less all together.
