With a brushless/lipo setup, the ammount of raw power is untouchable by nitros. The speed/rpms that an electric motor is untouchable by nitros. Living in an apartment complex, it makes it much much easier to test my different setups because i dont have the noise of nitro. There is a much much greater range of tuning that you are able to do with an electric. With most modern ESC's you can adjust EVERYTHING. You can fine tune your rig to your driving style, instead of having to adjust your driving style to the rig, like you have to with nitros.
You can adjust a Nitro car to your driving style as well...it's done through chassis, radio, and clutch adjustments. You can get the same type of setup out of both with some trial and error.
Electric Pros:
-No need to learn how to tune an engine
-Swapping pinions for track conditions is easy
-LIPOs provide TONS of power for the electric motors
-No need to buy fuel every week/month
-Easy to maintain
-Cheaper to stay racing once you buy in
Electric Cons:
-Good LIPOs are pricey
-LIPOs are very volatile and if you don't treat them correctly, you can watch your car (or workbench) go up in flames
-Good LIPO chargers can be pricey
-Runtime is limited to how much you want to spend on batteries
-More expensive to buy in and start racing up front
Nitro Pros:
-Feels more like "real" racing with the sounds and smells associated
-Runtime is only limited to the amount of fuel you have on hand. Running a 1 hour main is easy.
-The satisfaction of hearing a perfectly tuned Nitro engine humming along is enough to give you an ego boost!
-More widely raced at the moment in 1/8th trim, but electric is slowly gaining momentum
-Cheaper to buy in and start racing
Nitro Cons:
-Engines *can* be hard to tune if you are inexperienced
-Harder to maintain (Clutches, engine parts, filters etc etc etc)
-Noisy, so it can be hard to run them in a residential area
-Dirty, nitro fuel gets EVERYWHERE
-Smell, Nitro smells like toxic waste as it's burning
-More expensive to stay racing once you buy in
They are both GREAT to play with and race. Electric makes everything easy, but at what cost? I see a lot of electric guys just charge batteries and go...neglecting their rigs because they don't need to tear them down each week and such. They take them for granted a lot more than the Nitro guys do. Nitro guys are forced to wrench their rigs every single time they drive em if they want them to stay in tip top shape. A nitro runaway is a SCARY thing to witness....
Nitro wins in my book...and I have raced them both....but Electric is fun as well. Just not as much fun for me personally....
