- Lithium Polymer (LiPo) is a different chemical composition than standard Nickel-Metal Hydride (NiMh), that's why they need to be charged differently.
- "ST TRIM" = How straight the car goes (precision adjustment of the steering)
- "ST D/R" = "Dual Rate", it adjusts how far your wheels will turn. If you adjust your knob from 0 to 10, the wheels will only travel 10 degrees on each side instead of full 45 degrees. This is usefull when doing very high speed run.
- Servo is the part (little motor) that controls the steering.
- ESC stand for "Electronic Speed Controller" and controls about everything in your car.
Advantages of brushless motors:
-Less required maintenance due to absence of brushes
-High efficiency, no voltage drop across brushes
-High output power/frame size.
-Reduced size due to superior thermal characteristics. Because Brushless Motors has the windings on the stator, which is connected to the case, the heat disipation is better
-Higher speed range - no mechanical limitation imposed by brushes/commutator
-Low electric noise generation
- Basically you just need 2 channels to drive an RC car (throttle and steering) but in some case a 3rd channel can be used for different things. Like on a Crawler to activate the "multi-select 4 wheel steering modes" or on planes to activate the landing gears.
