Well once again I guess it comes down to whatever you can find parts for.
Have you seen any nitros run before? They are fun to drive, and the sound gives you an illusion of speed, and the whine as it powers over and through obstacles are insane. It is great to hear a nitro mill running, and even better when you know it's working. You get that really low grunt that just says "Power." That's one thing electric can't match, inless your running steel gears that are really bent and warped. Then you'll just sound like a rusty fire engine.
I am going to upload a new nitro video to our
Movies page soon, so check it out if you've never seen a nitro run. This one I left the sound in, but there is still some cool music. Don't tell Breaking Benjamins, but I had to "Borrow" their song!
