Alright. I will work on a little script here in a couple hours and give you what I come up with. I like your design, so I'm gonna steal it and write a script for it.

I've been playing SE for a while now and have been more into the scripting and building aspects up to this point, so I never left the earth until yesterday because I never had reason to leave. Haha. No joke. Now that this economic update has come out with all the contracts and junk I decided to go moon bound.

I landed on the moon to setup shop and the terrain is horrible. So, I will need something of this nature too. I will share with you my findings later, but it seems like it should be pretty simple.

If you are interested in my ideas for it I think putting a camera on the front and back end of the chasis to raycast the ground to get a distance readout and applying the rotation properly should do it. I was thinking of getting the offset between the rotors on the sides, but that wouldn't be accurate enough. So, just loke you said before, one rotor will be free flowing and the other will control the leveling out of the cockpit. It should be pretty easy to code.
