There are other ways to look at nitro vs electric
Nitro:
-you need a pitman if you plan to race
-can't run it everywhere thanks to noise
-more maintenance (clutch, glowplugs, air filter, engine tuning)
+runtime
+generaly more people at races
Electric:
+quiet
+more power (however needs practice to control it)
-racing runtime ~15minutes unless using very heavy batteries
-still not as popular as nitro
