i recentyl got a ravager and half to say i was very impressed, i use it for bashin but man no matter what i did that thing wouldn't break.
At one point we were in this huge excaveted area and looking for the biggest jumps, it was amazing to see that thing fly in the air and just keep hummin along. I don;t know how it will be on the track, but i don't think i have ever had so much fun in four hours with a rc car. And yes we were running tanks back to pack, probably would have kept running but all our batteries for the receiver packs were dead.
So if your worried about durability the ravager is great. the only think i need to figure out is the brakes... i think i have the bias messed up
