Question about Z-car engines???
Z-cars list their engines as 2.2v, 2.6v, and 3.0v. Everyone else (Zipzaps, Microsizers) seem to list their engines in RPMs. So I was wondering if the 2.2v mean 22,000 RPM or if it really means 2.2 volts? It has a 2.2v engine standard and is pretty zippy altho, has some trouble steering on the carpet in my office but maybe a 3.0 engine would make it go better?
