Linkage (throttle. brake). Heavy gauge wire is used to connect servo horns to throttle and break controls. Mechanical Speed Control(MSC). The MSC is a servo-driven device that uses resistors to regulate power transfer from the battery to the motor as a means of throttle control. MHZ=Megahertz. Unit of radio frequency. Surface frequencies are 75 MHz and air frequencies of 72 MHz, and 50 MHz can be used for either ground or air applications. However, a FCC license is required to operate on the 50 MHz (am radio) band. Muffler. All nitro-powered cars use some type of muffler to reduce the noise output and provide pressure to the fuel tank. Needle Valve. A nitro engine can have from one to three? adjustment needles on the carburetor. They are used to adjust the air to fuel ratio. On most engines, the needle is turned clockwise to lean the mixture (allowing less fuel and more air to enter) and counterclockwise to richen (permitting more fuel and less air to enter) NiCad (or nicd ) Rechargeable Nickel cadmium batteries, most commonly used to power radio transmitters and receivers. Also used in stick packs in electric vehicles. Nickel-Metal Hydride(Ni-MH). Battery cells that do not have ¡§cell memory¡¨ with slightly less voltage than nickel-cadmium batteries. For the average enthusiast this means less maintenance. Nitro / Nitromethane. This is a fuel additive that increases a model engine¡¦s performance. The ideal nitro content (measured by percentage) varies from engine to engine, but you will typically find 10 to 30 percent on the hobby shop shelf.
