Maybe they simply made them dynamically change their thrust/lift force
Yeah, well, I think the new hover plate stabilisation code will mean that their force should vary dynamically, depending on the motion of the tech. So different forces may be exerted, even when the ground is at the same distance from them, depending upon if they are in upwards or downwards motion, etc.
But the max force, when you have a (hub) wheel right adjacent to them, appears to be the same, in a stead state pose, at least.
