If you are new to rc car racing, especially off road, it would be much simpler for you to go electric to start with. You have so much to learn about setting up the car, not to mention learning to drive, and with electric you don't have the added dimension of having to also learn to tune and run a nitro car engine. With a properly built electric car you can simply drop in a battery pack and run it, which will allow you to concentrate on the actual control and set up of the car. I've seen plenty of people that started with a nitro rc car and dropped the hobby from frustration with not being able to get a handle on the engine quickly enough. Rather than learning to drive and set up the car they spent all their time trying to get the engine started, or keeping it running, or shagging their car after it stalled. Get a Losi RTR truck, a decent battery charger, and a few decent stick packs and go have fun. If you decide you like rc car racing and want to move up to nitro, sell the electric, or keep it and race two classes.
