Well, from my past experience with a 2s in my Hyper 9e the car was really easy to drive at the limit of my skill. I felt like I was way more consistent when driving very hard. Honestly, to me it was just more fun to drive like this than to baby it around with a powerful 4s setup. The thing I didn't like about the hyper 9e was the inconsistent chassis response that the car seemed to always have. I don't know if it was the shocks or just the chassis design, but I always had a heck of a time keeping that car rubber side down. The slightest variation in track surface would upset the balance of the car especially on power through corners. If the track was nice and smooth it was a really fast car around the corners, but a whole different story when the track was not perfect.
