How much does different modules impact the ship weight and how much of a weight difference is there between different modules. Ex: Fully equipped ship with the heaviest modules out there [module weight] = 1 * [Hull weight] and lightest modules possible [module weight] = 0,1 * [Hull weight].
Not full determined as everything hasn't been designed and balanced - but the hull weight and module / cargo weight definitely play into the calculation s. I estimate it will be like an aircraft where half the weight can be air frame and half cargo.
