Shows the rotors aligned vertically, and i also added some bump stops to give it a more smooth suspension operation, with those you dont need the hinges to push down:

Im not reccomending you add a sway bar like in the video to your design, but in my recent designs ive started using Tekk's subgrid wheel control script instead of whip's. Because it has anti roll as a feature in the script, where it will make the vehicle's suspensions try to counter the roll by reducing height offset into the turn (disabled by default)

Last point is i would probably reduce the length of the rods by 1 block to make it more compact, as i dont think that will do much to change the functionality, but will improve how easy it is to build around it if you want to have a full vehicle on top, and possibly reduce the low angle so its less likely to bottom out when you turn off the hinges or it hits anything too hard.

I like it!

I like, it, its a good start. I would advise you to align the rotors so they are vertically aligned instead of offset by 1 block. And i would reccomend you turn on "share innertia tensor" on all rotors (not hinges) that will increase stability by a large factor.

Main issues it has is when testing is when turning, it wants to roll, which is something a lot of my designs also struggle with, this can be ammended by having gyroscopes with override set to on, so it doesnt want to rotate, but that may interfeer with steering. it looks like you solved it by decreasing top speed and power.

This video shows the body roll im reffering to, which is amplified in designs where the suspension is free moving on all wheels like this one and a good few of mine (ignore that its a commercial)
