HPI Vorza Flux... Hot Bodies Ve8... E-Revo...

[Topspeedtimmy]

Just a thought about deciding between the buggy and your current Revo: It doesn't seem wise to just buy the first interesting vehicle you see. Take your time. Also, it could be possible to get your REVO to handle with a little more agility (similar to a buggy). Here some things that could help- truggy tires, sway bars, thicker shock oil, possible P3 rockers, tougher springs, maybe even a lower pushrod setting or less preload.
I don't think a buggy will like cruising through the grass at high speed as much as a REVO if that's what your going for.
