The actuator is a mechanical device used in many fields that can be powered by air, electricity, and other means and causes a motion of some kind.
On some micro RC vehicles, in place of servos to control the rudder or elevators or steering you'll find one or more lightweight actuators.
Actuators don't provide the same precise control as servos because they are either on or off but their small size and light weight makes them useful in micro vehicles such as tiny infrared cars or the tiniest of RC airplanes where traditional or even micro servos would be too large and heavy.

RC Glossary - Actual Speed
Fastest Actual Speed of an RC:
If clocked a RC vehicle at top speed using a speed gun, will probably get a speed anywhere between 10 to 70 mph. Some dragsters and specially modified RCs can top speeds in excess of 100 mph but that's the exception and not the norm.
Actual Speed and Size of an RC:
There is a loose relationship between the size or scale of the RC vehicle and its actual speed. A 1:10 scale RC would go about 1/10 the speed of the full scale vehicle it's modeled after. This doesn't always hold true. RC toys, especially those for toddlers and pre-schoolers are much slower. Some modified RC vehicles may have actual speeds that are much faster than you might expect for their scale size.

Know Your RC : Radio Frequencies for Radio Controlled cars and Vehicles
In radio controlled cars, frequency is specific radio signal sent from the transmitter to the receiver to control the vehicle. Hertz (Hz) or megahertz (MHz) or gigahertz (GHz) is the measurement used to describe frequency.
In toy-grade RCs, the frequency is normally a set channel within the 27MHz or 49MHz frequency range. There is a greater variety of channels and additional frequencies available in hobby-grade vehicles. These are the most common frequencies used in both toy and hobby RC vehicles in the United States.
27MHz:
Used in both toy-grade and hobby-grade RC vehicles, there are 6 color-coded channels. Channel 4 (yellow) is the most commonly used frequency for toy RCs.
-26.995 MHz - Ch 1 (Brown)
-27.045 MHz - Ch 2 (Red)
-27.095 MHz - Ch 3 (Orange)
-27.145 MHz - Ch 4 (Yellow)
-27.195 MHz - Ch 5 (Green)
-27.255 MHz - Ch 6 (Blue)
49MHz:
49MHz is sometimes used for toy-grade RCs.
-49.830 MHz - Ch 1
-49.845 MHz - Ch 2
-49.860 MHz - Ch 3
-49.875 MHz - Ch 4
-49.890 MHz - Ch 5
50MHz:
Although 50MHz can be used for RC models, it requires an amateur (ham) radio license to use these frequency channels.
-50.800 MHz - Ch RC00
-50.820 MHz - Ch RC01
-50.840 MHz - Ch RC02
-50.860 MHz - Ch RC03
-50.880 MHz - Ch RC04
-50.900 MHz - Ch RC05
-50.920 MHz - Ch RC06
-50.940 MHz - Ch RC07
-50.960 MHz - Ch RC08
-50.980 MHz - Ch RC09
75MHz:
For surface RCs only (cars, trucks, boats). It is not legal to use this frequency for RC aircraft.
-75.410 MHz - Ch 61
-75.430 MHz - Ch 62
-75.450 MHz - Ch 63
-75.470 MHz - Ch 64
-75.490 MHz - Ch 65

-75.950 MHz - Ch 88
-75.970 MHz - Ch 89
-75.990 MHz - Ch 90
2.4GHz:
Is used in more and more RC vehicles, this frequency eliminates problems of radio interference. Special software within the receiver and transmitter work to set the specific frequency channel within the very wide 2.4GHz range, locking out interference from other systems operating within the 2.4GHz range in your operating area. There is no need to change out crystals or select specific channels yourself. The transmitter/receiver do it for you.
In toy-grade RCs, the frequency is normally a set channel within the 27MHz or 49MHz frequency range. There is a greater variety of channels and additional frequencies available in hobby-grade vehicles. These are the most common frequencies used in both toy and hobby RC vehicles in the United States.
