Thx. Haven't clocked her, but she's so fast I get nervous at WOT. I'd guess around 45-50 mph or so. Too fast for a truck honestly. Traction is the hardest part. Even Med Komodo dragons spin to baldness in no time if I'm not careful. I had to get some street tires for when I mess around on the street or I'd go through dirt tires within minutes. Runtime is like 25-30 minutes just fartin around at the tracks.
