LOL - I haven't had a dog since I was a kid - love dogs, though! The sound of nitro definitely has a "cool factor" that draws a crowd and gets the adrenaline pumping - I prefer the instant power and low maintenance of electricity, but I get nitro, too - raced nitro along with electric for years and loved every minute of it(aside from the nitro mess). Nitro tends to annoy the neighbors as well.

I think diffs must happen before a big block chassis - there was a big block conversion for the Revo trucks available years ago - not sure if it still is, though. Big block T-Maxxes used to be the rage a decade or so ago, which ultimately led to hybrid bulks and ultimately led to what we now call truggies.
