for us americans 10mm = almost 1/2"
i seriously doubt that your buddy has had that much play in all suspension parts i think you are just trying to bash the hyper 8. if you have a legitimate complaint about the car tell us about it in a truthful way not outlandish lies. i have 2 gallons on my hyper 8 and it doesn't have any more play than my jammin buggy. did at the same time and less play in the universals.
1 or 2 gallons which is it that is a huge difference in run time if you want to bash the car your method shows no signs of validity
