The Foam is from the Battery slots of my ProMatch Battery Box Holder. I need something stiffer becuse the batter will move in a major impact. I also put it in the front bumper to stiffen it up a little.
I have not had a chance to drive the cars yet and will not have a chance for 2 more weeks
. I do have better control on my hardwood floors going after my cat with the cells at 6.45mm in
. Both cars are balanced pretty well on my tweak board. But I can twist the 6.45chassis really easily and make the car majorly tweaked. I am going to get some Graphite and cut some center braces for the car.
