Thrilling Radio Controlled Dirt Racing
Electric RC off road cars can be made using one of four different types of rechargeable batteries: nickel-cadmium, nickel-metal-hydride, lithium-ion, or lithium-polymer. Each of these has benefits and drawbacks for a hobbyist. The nickel-cadmium (NiCd) battery was the original battery in RC off road cars for hobbyists. The cadmium makes it very difficult to dispose of, and it suffers from memory effects (that is, over time, it can lose its ability to hold a charge). [...] Read more »
Within the last few years, there has been a recent technological development that has helped to close the gap in power between electric cars and nitro-powered cars: the brushless electric motor. This is a quality new design that greatly improves the efficiency of an electric RC off road car, as opposed to the old brushed motors, which were not very high quality for this great hobby; you can do powerful things with an electric car [...] Read more »
