How to exclude parts from game physics

[TheReaper]

Hello guys,

so ive been making some spaceplanes recently and ive noticed they all tend pitch up or down even if the plane was made almost 2 dimentional, i think its becouse of landing gear though ( it didint happen before with landing gears and near only affects aerodynamics (as far as i know - no vaccum physic improvement- ) maybe its a bug but its a report and question for another story and another time - unless you faced the exact same problem ,please share info-)

now the stock landing gear is out of game physics along with other parts i was hoping if i can do the same thing for b9 landing gears that i generaly use, is it possible ? if so how?

Although these seemingly physicsless parts do affect aerodynamics and my center of lift slightly ( becouse i have NEAR installed) any chance to make these parts and the b9 landing gears also immune to NEAR aerodynamic detection as well as gameplay phyics calculations for mass.

Thank you

Physicsless parts have this line in their part configs:

PhysicsSignficance = 1

I haven't used B9 since KSP 0.24 came out, but I think this ModuleManager config would get all of them without touching anything else:

@PART[B9_Utility_Landing_Gear_*]
{
    PhysicsSignificance = 1
}

You should also read this tutorial on aircraft which might solve your problems without changing physics:

You can add PhysicsSignificance = 1 to any part's .cfg file to remove it from mass and stock drag calculations. NEAR/FAR have to take the shapes of physicsless parts into account because of oddities like the 3.75m decoupler, and I don't think they give you any way to mark a part as dragless.

Thanks guys! apericate the help. now to get on work with some cfg editting.
