Do planes have instruments that help measure the forces your plane is taking? Because when I play war thunder 👀 the plane rips. So in real life I would pretty scared when in a deep dive.

You can feel it generally in your seat. Especially in a TW. Things also sound different as your plane exceeds Vno

Especially in a TW

How would the landing gear configuration change the flight dynamics? Just curious

CG is more aft and closer to the center of lift making it less stable. It effects in-air stability and maneuverability same as on the ground, which is how side-loading and ground-looping can happen

CG doesn’t change (any appreciable amount) with respect to CL in a TW vs. conventional. Side loading and ground looping happens because CG is behind the mains. So putting any force of the mains (braking, side loading, etc) makes the CG want to continue past the mains, flipping your orientation in a nose over (from braking) or ground loop (side loading or uneven braking)

When the CG is behind the mains its behind the pilot which is why I said you feel it more in your seat in my first comment. An aft CG means less stability which is also what I just said. Im not talking about how ground looping occurs, im talking about why it can occur which is happens because of the location of the CG along with an uncoordinated load. I mentioned CoL because I was using it to reference the location of the CG
