Fast!, durable!, offroad!, brushless!, cheap?

You say in your original post that you want a 1/10 or 1/8 buggy/truggy.

Have a look at the CRT.5. It is ~ the same size as a 1/10 scale buggy, but much stronger (the drivetrain is 1/8 based), and the suspension is a bit stronger too. They aren't that expensive, conversions of them are easy to come by, they have the truggy look you're after, and the electrics will be cheaper - you could run them on 3S Lipo, which means the ESC will be cheaper, you don't need such a decent charger, or if you have a 6S charger, you could charge 2 at once, and the 3S lipo would be cheaper than the 4S (or more) ones. Also you don't need a really big/powerful motor as they are much lighter than an 1/8 scaler.
