Was out doing some speed runs yesterday. Mmp 2650 and 4s battery. I was able to dial it in so it would stick to the ground but tires were still breaking louse a bit at about 3/4 throttle. So I lowered the front more and it was doing well. Second run the tires blew right off. Anyone have any recommendation for 17MM road tires? Also is the traxxas GPS out yet? I would like to see where my speed is getting. I can't do the spur gear telemetry becouse I hsve a Robinson racing in it.
