Common Terms Explained for RC Cars (Part 2)
Commutator is also known as 'com' for short. It is the part of the rotor (the part inside which turns) which has three copper contact for the brushes to run on. Keep clean and skim regularly for optimal efficiency and motor life. Brushes are the two copper contacts that supply power to the commutator of the motor. These should be replaced regularly for optimal efficiency and motor life. When a motor has been used several times, the commutator can become deformed, thereby reducing the motor's efficiency. Skimming refers to placing the motor's rotor on a small lathe and turning-down the commutator so that the surface is smooth and round again.
When two or more drivers in a race are using the same frequency, causing interference to one, or both of the drivers it is known as Frequency Clash. All radio-controlled equipment uses crystals to set the frequency which they operate on. Crystals resonate at a set frequency when an electric current is passed through them. They are very delicate and should be stored and handled with great care. Crystals come in pairs, one for the transmitter which is marked 'TX', and one for the receivers which is marked 'RX'. Make sure you use the correct crystals, it DOES make a difference.
A car dives when it is under heavy breaking. This is because of the momentum the car has built-up is being resisted by the breaking force of the motor. The front slings store some of that energy by compressing, this making the front of the car drop. Dive is the opposite of squat. When heavy acceleration is applied to the car at relatively low speed, the forward force exerted by the motor is resisted by the inertia of the car. The rear springs store some of this energy (temporarily) by compressing, thus making the rear of the car drop. This is known as Squat.
Dampers absorb the excess energy stored by the strings when the car goes over a bump. Without dampers the car would bounce up and down uncontrollably. But when you car has just has so much grip that the body roll is just too great, causing the car to completely roll over onto its side it is known as the Grip Roll.
Electronic Speed Controller (ESC) is the electronic box that takes the throttle/brake signal from the receiver and feeds the appropriate amount of power to the motor. But when your car makes a sudden twitch causing you to lose control, it is known as the Glitch. This is usually due to some sort of electrical interference. Transponder is a small electronic device which when fitted to your car, registers that you have completed a lap every time you go past the start/finish line. This is how your race result is recorded, so don't forget to fit it or you won't register any laps!
Trim is the setting on your transmitter which determines whether or not the car runs in a straight line when the steering is in its neutral position. When making a turn the car fails to turn enough, instead preferring to go straight. This is called under steer. On the other hand if while making a turn the car turns to much, making the rear-end slide it is known as the Oversteer.
Rostrum is a raised platform for drivers to stand on whilst racing, so they can get an elevated view of the track. TQ or the Top Qualifier is the man with the fastest qualifying time overall. BRCA stands for British radio car association. It is the governing body of the sport.
Inserts are foam or rubber rings placed between the tire and the rim to help the tire keep its shape. Apex is the exact mid-point of any given corner. This is the point where you should be closest to the inside of the corner. Kick-up is the angle of the front wishbones to the ground.
