Q. What is the difference between Kits and RTR (Ready to Run)?
A. Kits are a set of parts or materials necessary to complete one car and must be assembled by the user. RTR (Ready-To-Run) are factory built vehicles that are ready to go out of the box. All of Tamiya’s high-performance racing vehicles are produced as kits as this allows the racer to build and setup the vehicle per their needs.
Q. Why do I need ball bearings?
A. Bushings are soft metal sleeves, often made of bronze and other metals, installed on rotating and spinning parts in a RC car. They can also be made of soft plastic with low friction properties. Both these types of bushing require lubrication to keep friction to a minimum. Over time bushings will wear out and cause friction in any rotating or moving part if not lubricated frequently. Spinning and turning parts will also not turn smoothly and quickly and will begin to wobble. Ball bearings allow every moving part in your vehicle to transfer power more efficiently because the bearing is constructed of an inner and outer metal race, which contain metal balls. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most RC car applications, one race is stationary and the other is attached to the rotating part such as a wheel axle or idler shaft of a gearbox transmission. As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other. Note: All TRF kits are outfitted with ball bearings. In some cases the kits are equipped with ceramic ball bearings, which are capable of a high degree of spinning speed and run cooler compared to standard steel bearings.
Q. What kind of Paint do I use to paint my RC car body?
A. Tamiya has formulated its PS Sprays specifically for lexan/polycarbonate bodies. With proper use, they will give you not only the best looking bodies on the track, but stand up to the rigors of racing. Tamiya’s PS sprays also have flex characteristics that won’t crack when the body is subjected to normal impacts.
Q. Do these RC cars go in reverse?
A. Electric vehicles can go in reverse if equipped with an ESC (Electronic Speed Control) that has reverse capability. TRF Nitro vehicles are not equipped with reverse as it is not desirable. Having reverse capability would require a complex transmission which in turn sacrifice overall speed and performance. It's also common practice to disallow reverse in a race track environment. The use of reverse in a race track environment is a recipe for unintended crashes and collisions.
Q. Where can I buy these vehicles?
A. Your local hobby shop is your first source for Tamiya products, not only will they have the products, but the experts to help you in your time of need. There are also many online retailers as well as Tamiyausa.com that are open 24/7.
Q. I don't plan to race, is a TRF vehicle still a good choice?
A. Tamiya’s TRF line-up of RC race cars utilizes the best materials for the job that is available. The use of carbon fiber, high-grade aluminum, titanium and carbon reinforced plastic are used throughout the car to squeeze every precious fraction of a second on the stopwatch. If you plan to race and race often TRF race cars spare no expense in achieving the best possible tolerances for maximum performance. If you don’t plan to race Tamiya offers mid-level RC car kits that offer exhilarating speed and performance with the option to grow with the many Hop-Up-Options available to enhance your vehicle to club racing specifications.
