picking up where the tyco rebound left off, the nikko vaporizr 2 is a 4wd, tank steer RC that can also go in water.
While that is cool, for most of us the hard plastic tires which lack traction, the 9mph top speed and short runtimes would dampen the fun.
But no vehicle like this exists in the hobby rc world.
Now, just imagine a larger version, with Emaxx sized tires, capable of 30mph, with proportional steering! That would certainly be a blast to drive.
