not ran this buggy for months, so as I had a couple of new 8s batteries, I decided to take it out on a longer "runway" and run it on 16s! the alien esc, surprisingly or maybe not, worked straight away, once it had traction (as you would expect on 16s) it was ballistic, no gps didn't save to "history" only thing that broke was gear shaft that fits on motor and holds the "A" gear not sure why? but will get another and try in the dry, the esc took all that was thrown at it, must be a different version, just keeps going, hats off to Bruno, whatever he did, shame it's not got the features of the max5,
