Yea, it is just right on 7.4v. Kinda scale speed and not out of control fast. I accidently wired my batteries in series instead of parallel, in other words made 14.4v. That was just stupid fast! Looked like the 14.4 boat on youtube, really useless. I ended up putting a 4300mah 2 cell lipo in it. The runtimes are crazy and the little bit of extra weight actually made the boat handle better.
