Evader.
Read as much as you can here and anywhere else you can find info online on the evader and nitro trucks in general before you buy. When going nitro, you'll need as much preparation as possible to avoid frustration. Nitro isn't easy when you first start. If you're willing to learn, it gets much easier very quickly. The more you read ahead of time, the less frustration you will have when you get your truck.
