In theory 53.75 MPH with an rc calculator. On 6 cells the exact same setup gets 27mph gps verfied. I will try to GPS verify the top speed, but I cant do onboard video & GPS simultaneously, I have to choose. I would bet my last dollar its hitting 50 however.
It is officially the fastest RC I have owned.
Thank you Traxxas engineers (and everyone) for a fine job.
