Nitro RC Cars are nitro gas powered radio-controlled or remote-controlled cars. These cars are fueled by nitro methane that delivers oxygen to engine which enhances combustion and delivers more power, methanol that provides main energy source, and oil mixture (e.g. castor oil lubricants), that can be controlled from a distance using a specialized transmitter; and can be operated like full-sized fuel vehicles such as two stroke engine that burns up nitro methane, thus achieving higher maximum speeds than gas powered cars. The nitro-powered cars does not need unnecessary stops to prevent engine from heating up since it can be refueled in a few seconds and cooled by air or oil mixed with fuel; and can be run continuously with no need to take breaks for cooling down. The nitro RC cars have many more parts than most electrics.Unlike battery electric cars, nitro rc cars are noisier but can run for a longer period of time with improve performance, durability and power, making them ideal for outside use such as racing either on-road or off-road. The off-road nitro RC cars (e.g. buggies, trucks and monster trucks) are built with functional off-road suspensions such as aggressive off-road tires and long travel suspension that can be used in different types of terrain where speed, power and durability are perfectly applied. The on-road nitro RC cars are designed for high speed and maneuverability to be raced on the streets or any other surfaces; and have non-existent suspensions such as radial tires and stiff suspension which are limited to smooth and paved surfaces, thus providing fastest top speeds. Unlike the off-road cars, on-road cars can be easily damage if crashed. Since nitro cars have increased speed and weight, this generally lead to higher speed collisions which results to greater damage on collided cars, thus greater degree of safety concerns must be taken into account. However, the exhausts of both cars contain unburned oil which usually ends up coating the chassis; thus requiring more cleaning by the use of compressed air nozzles and solvents, e.g. denatured alcohol. When operating RC cars, one has to learn in maintaining optimum performance and fuel economy so that engine wear and overheating is prevented even in ready-to-run vehicles.
