Wheels spinning

@pedro16797 yep

@UnitedAerospace as I said there are mainly 3 factors, you have to account for the 3

So you are saying that without suspension the vehicle will behave normally @pedro16797

@pedro16797 oh ok thanks :)

There are three factors making this happen. You have parts that aren't connected to the craft and that first push makes the craft move a bit; you have suspension in the wheel and suspension in the axis, the two combined aren't stable and cause the physics engine to behave a bit unexpectedly; and you aren't in a static environment. That last one means that you have suspensions, the CoM won't ever be perfectly centered because of the nature of floating point precision and you are on a flat runway on a spheric planet, which will pull you towards the center of the runway. This isn't as noticeable on Earth, but in a planet with 1/5 the radius it can be noticeable.
