Received this kit as a Christmas present. Packaged nice and safely from RCmart. Great reproduction of the original XR311 released 40 years ago. Lots of alluminum changes that have brought added durability. Kit comes with metal bushings and a few ball bearings. Plastic parts are of high quality and detail, tires are nice and soft too. Keeping true to the original, the kit comes with a silver can motor. I believe that this motor is very efficient in this kit. If you want a slower speed change the gear ratio (3 options to choose) or drop in a 35T Tamiya CR Tuned motor, for slower speed and more torque. Do not need a lot of torque for this kit because it is 2WD.
