Understanding how important the cleaning and maintenance of RC vehicles is, Ultimate Racing have added this new Dirt-Off car cleaner to their range. Dirt-Off is a multipurpose cleaner that can be used with all types of RC vehicles. With its specific formula, it is capable of penetrating and descaling any adhering dirt particle such as mud, grease, dirt and general grime. Dirt-Off is very effective on metals and plastics, cleaning any part while lubricating and protecting against corrosion. Thanks to its adjustable spray, it disperses and spreads easily, leaving a protective film that prevents the accumulation of dirt.

The backplate has been updated to improve the gas flow going to the piston and improving engine efficiency and performance. The crankshaft of the MXS is an evolution of the DLC B2102 but with two balanced tungsten in order to increase the inertia to rotation.

New from Ultimate Racing are these useful 1/8 offroad insert rubber rings. Manufactured to fit into each of the insert’s grooves, once fitted the insert is practically fixed to the rim. In this way, the insert is prevented from moving laterally, improving stability in fast corners. It also prevents the insert from ballooning making the car much more stable under acceleration. They can be used on most inserts, wheel brands and compounds, but their effects are greatest on soft compound tires. Depending on whether you want the insert to be more or less fixed, they can be used in all three grooves, in two or only in one. They are sold in bags of 50 pieces so that you can assemble from 4 to 12 complete cars depending on the amount of rubber bands used per insert. Once the life of the tire is over, they can be reused as many times as you want.
