The Xray is a rear motor. Used Xray are great as they are very durable cars. I've crashed mine very hard and rarely suffer from broken parts, breaks happen but usually follow a very violent mishap. Regardless of brand you will get very familiar with how to assemble/disassemble the car for repairs and maintenance. An added bonus at most tracks there are enough Xray drivers to help you identify problems, offer a replacement part and offer setup suggestions.
