I agree with what everyone says. Plus 1/8 is a lot more fun than 1/10! The Stampede 4x4 VXL is waaaay overpriced for what you're getting.
The Savage 2350 is so much stronger in every category than the Stampede 4x4 not to mention it's COG is lower so handling is much easier and predictable....just think about it. Why does Traxxas have so many upgrade parts for the Stampede 4x4 and so many aftermarket companies as well such as MIP, RPM, and FLM.
If you look on YouTube check out Jang's review on URC (Ultimate RC) on the Stampede 4x4. The first thing I'd do if I was dead set on the Stamede 4x4 is to swap out all the A arms to RPM's....then upgrade all the drive shafts from Traxxas' damn plastic shafts to MIPs. With all that said and done you've already paid more than a Savage 2350.
