I'm also wondering if the VXL setup is anything close to a 17.5 setup. I know it's a 3500kV motor but not sure how that translates to something like the 17.5 numbers. If it's the same, that would help me out as well. I'm looking to run brushless instead of brushed in the spec class here since they allow it and hope that the VXL will work (although I doubt it).
