The older E-Maxx has decent steering but the stock servo isn't quite strong enough to turn the wheels while it's stationary. No big deal. As for speed, it's possible the stock motors' brushes and commutators are worn out; don't expect anything more than 25 MPH stock in second gear at best though on 12 cells.

There is tons of potential in the old E-Maxx. Hope you enjoy, and ask away with any specific questions.
