No I don't think so TJ. Chris N said he was using a Tenshock 5200kv 4 pole motor geared with a 13 and it was hauling. I know the std 4200 will pull a 13 well and also the 4800 is a handful on the track geared with a 13 so really comes down to dollars maybe. Let me know how much the Tenshock is, might consider one for insanity.
I think you'd need a different speedo for the 4 pole. Not really up with it as I used to race nitro buggies. I'm happy with the 4200 geared at 12 for track work and even that can catch you out with unexpected wheelies etc. I looked at motors and speedos from LHS and the combo was nearly as much as a VMX at the time. I just bought another VMX instead for parts. Got spare radio speedo motor and every part. Maybe see if you can find any still floating around new.
