Electrics have shorter run times because when a battery pack is dead, you have to stop and wait around for it to recharge.
As for nitro, you could run it for days, you can just top off the tank when it gets low.

Charging a battery is not like re filling the tank. You don't have to kill the engine to re fill the tank. But with electric, unless you have a bunch of batteries ($50 - $100 + each). You have to sit there twiddleing your thumbs for twenty minutes not running your car, while the battery charges . With nitro theres not waiting around just fill up and go
