RE: I need some quick advice.
Revos and Savages are both great trucks. Much more suited to bashing than anything by AE or Losi. Those are race trucks and are simpy not as durable.
I'd either go for an E-Revo (no need to settle for nitro) or an HPI Baja and go big. A brushless Baja would be really cool, but would be prohibitively expensive in a vehicle this size. Therefore, gas and not nitro is the way to go. With these, you'd need a lot of space that doesn't mind noise though. It is like a weedeater with a bad muffler flying around at full throttle.
