Hi. First of all thanks for making this. and making it easy to use 
i have played around with this for a bit now but i have some problems with friction. It Looks like its in the compiled version you uploaded as well.
The problem is that even if all my friction-points says static the tank still slides. And if i set the friction higher it slides less but will start stuttering when on flat ground. Not a lot, but it will never stop to move.
Am i making the wrong assumption that when the friction is using static it should more or less be glued to the ground?
