Losi's lineup of Race Rollers provides a fast and easy way to get up and running with a pro-built chassis. From the 8IGHT 2.0, 8IGHT-T 2.0 to the L8IGHT Model there's something here for many to enjoy. With each of these Race Rollers you will need some basic running items to get up and running, which can cause some confusion. After all there are countless servos, engines, receiver packs, starter boxes and more to choose from. We've polled the experts and gathered their opinions to help you get running with the right gear for you. We've broken them down into three categories; Casual, Intermediate and Hardcore. The items listed in Casual are for the more budget-conscious out there looking for a good value, easy tuning and adjusting along with reliable performance. The Intermediate products are a little more performance orientated but still save you some coin where possible. The Hardcore products speak towards the ultimate in performance, when compromise is not an option. We're sure you'll find something here that will suit your needs and your budget.

If you're looking for the performance of a digital servo but don't want to drop that much coin, then the JR Z4800 servos are the ideal choice. Similar in performance and design to the popular JR 8800 series of digital servos, the Z4800s allow you to have a high-performance servo at the price of an analog one. The Z4800 features a metal geartrain and precise ball bearings to
aid in precision and durability. There are two
versions of the Z4800 available, the
Z4800S (speed) and Z4800T (torque).


If there was a servo hall of fame the JR Z8800's would sure  be in there. These digital servos provide a fast response time, tight deadband and ultra-durable performance. The Z8800S features 105 oz of torque with a .08 transit time. The Z8800T boosts up the torque to 188 oz with a transit time of .15. These are two of the best servos you could bolt onto your chassis.


LiPo batteries have revolutionized racing and now you can take advantage of LiPo receiver packs thanks to the newest generation of High Voltage servos from JR. These new servos forego the need for a voltage regulator thanks to their ability to operate at the higher 7.4 voltage output of LiPo batteries. The Z9100HVS is lightning fast, featuring a .06 transit time and 230 oz of torque. If that's not
enough torque for you then check out the
Z9100HVT features a mammoth 480 oz of torque
while still maintaining a .12 transit time. Both servos
also feature a rugged aluminum case and
SuperSteel gears for bulletproof durability.
