Something happening to my wheels

[Vigelius]

I'm building a little runaround for zipping kerbals and gear around. Its going fine, except for something odd happening to the wheels when I launch it. Still drives as though the wheels are all on the floor, but it annoys me that they aren't!

Anyone got any idea what's going on and how to fix it?

Describe the odd situation in greater detail.

It might be a hitbox/suspension issue, similar things happen with landing legs. You probably only need four tires instead of six, though. (Also, nice design, a heck of a lot better than most of my ground vehicles.)

From the looks of it you have rotated your center set of wheels incorrectly. Try pulling them off and checkingvtheir rotation.

I'd need to see the mount of the wheel to see what's going on.

So, to elaborate a bit - in the SPH all the wheels touch the floor, and are direct copies of each other oriented the same way. Upon launch this happens. On the other side, both of the rear wheels move up into the same position as the middle wheel in the picture. I have tried with only 4 wheels and the same thing happens, but only at the back.

Nevertheless, the vehicle rolls straight and steers as though all the wheels are where they ought to be

Try moving that I-bar a bit more inwards (away from the wheels).

The easiest way to figure out what's going wrong is for you to post the .craft file so that others can have a closer look.

So I've spent a little time faffing about with this, shifting, removing and replacing things to isolate the problem. The issue seems to be the sloped I-bars underneath the wheels, but there only seems to be a problem when the wheels themselves are mounted on a structural panel. When the wheels are mounted on another I-bar (as in the picture below), no problem at all. Why this would be, I have no idea.

In the end, It became a service buggy I'm pretty pleased with. Case closed, unless somebody wants to hunt down the reasons for the I-bar/structural panel behaviour. Thanks folks!
