I just talked to Ace, and they are sending me out a new chassis tomorrow. I understand this is a new product, and what kind support I get matters alot more than the fact that it broke. So far the support is as good as I could expect.
I do like the S3, the acceleration is noticably better than my Kanai, and after the abuse this thing took last weekend, I would say that its a VERY durable car. ( except the broken chassis that cracked before it was driven or crashed hard ) Hey, I did jump on the S3 band-wagon, but I'm going to give it more time before I jump off it.
