Obviously it's nitro
I mean, c'mon, electric doesn't give you awesome smoke trails:
Really though, it comes down to personal preference. I now only own nitro vehicles, I cannot "stump" for electric anymore, but I can tell you what I like about nitro and why more people should try it.
1. The sounds and smells of a combustion engine. There's nothing like it.
2. It's no worse for the environment then electric. Electricity still needs to be generated, usually by fossil fuels or damming up rivers. Also, lithium mines aren't exactly "clean" or good for the environment. And in some cases using what is nearly slave labor. The amount of emissions produced by running a nitro all day long is about as much as driving your car to the end of the street.
3. You can run all day without recharging.
4. For course racing, it's the closest to the real thing with long mains and pit stops.
5. It's nowhere near as hard to grasp as people think, tuning is not only easy, it's fun.
6. The other myth is that you can't just "go". Uh, my trucks and cars start right up and I let em rip the minute I get there.
7. The lack of instant torque isn't really a bad thing, especially on loose surfaces like dirt.
8. You can do a lot more adjustments and tinkering to the drivetrain, such as clutches(to make up for the lack of instant torque), tuning, engine modding.
9. Learning throttle control is really cool.
10. Big block power can compete with brushless, I don't care what anyone says. I've seen modded SMALL blocks run legitimate 1.5-1.6 second 132ft drag runs, your typical 2s/3s drag cars are running mid 2's. Too many people try to compare Traxxas engines to brushless versions of their cars. Those are weak engines compared to Novarossi, SH/Dynamite, OS and others. A 4+ hp LRP .32 is a beast. You can do the math on what a 2s/3s brushless has, it ain't close to that.
