It bears mentioning that in terms of electromagnetic waves, microwaves, the wavelengths of which range from a millimeter all the way up to a meter, aren't particularly "micro".
At certain frequencies, such waves cause something call Dielectric Heating in water and fat, while passing straight through other materials, like plastic or glass, without exciting them much at all.
Metal, on the other hand, gets too excited. For a full explanation of how dielectric heating works, click here , but for the purposes of this article, just know this: Only certain materials are susceptible, and only when bombarded with waves of a certain frequency and power. One of those frequencies is MHz. Others fall at 5. But the one that proved to be both effective and relatively cheap to achieve was 2.
That's the frequency emitted by your microwave, right there in the kitchen. So, when the FCC got around to establish just which frequencies unlicensed gadgets could broadcast on, they had a lot of things to think about. First, they had to consider which frequencies were already in use by stuff like radio and TV.
Those would be off-limits. Then, of the remaining, usable, unallocated frequencies, they sought out the ones that were already being used by existing equipment. One thing they noticed? Microwaves were popular! They'd been around commercially since And generally, they operated at a specific frequency: 2. Despite heavy shielding, microwave ovens' powerful emissions could sometimes interfere with neighboring frequencies, so it was decided that they should be given a few megahertz of space in both directions.
And so the 2,to-2, We have a saying here. Understanding 2. More from: FAQs. Related Posts. Related Products. Latest Posts. July May April Should the connection between the transmitter and receiver be interrupted such as driving out of range, the transmitter batteries failing, breaking the transmitter due to a fall and so on the receiver will return the signals to the ESC and servo to neutral, effectively stopping the model from driving any further.
You can safely test or discover the existence of your model's fail-safe by placing it 'wheels up', accelerating so the car wheels spin before turning off the transmitter with the throttle still applied. If you are looking to purchase an advanced transmitter for your RC car, check our range of spektrum controllers , in particular the DX5 units. We are currently producing a series of short guide articles aimed at novices to the RC scene, browse our site to learn more.
Alternatively, if you have a topic you'd like us to tackle or explain, or have spotted any errors or emissions leave a suggestion in our comments section below.

Transmitter types When it comes to remotely controlling your RC car there several options available, but by far the two most popular ones are: Pistol Grip transmitter As the name suggests, these have a 'hand-gun' style layout. Stick transmitter Drone pilots and RC enthusiasts of a certain age will be more familiar with stick controllers. Transmitter Channels Traditionally channel one would be connected to your steering servo and channel two linked to your speed controller to control the throttle.
Transmitting over 2. Binding a transmitter The majority of transmitters that arrive bundled with models come pre-bound already connected to their respective receivers, but should you ever need to replace components in the package, you will need to follow these steps to rebind them. Transmitter adjustments Transmitters feature adjustment controls that alter the signals the receiver controls the model with. Trim Adjustment Trim adjustment allows you to finely tune the inputs from your transmitter.
Reverse switches This is pretty self explanatory, flicking this will reverse the signal sent from the transmitter to the receiver. End-point Adjustment End points can be adjusted individually for left and right, as well as forward and back. Exponential Adjustment Found on higher-end controllers, an exponential adjustment will allow you to modify the behaviour of your transmitter inputs. Powering up The majority of transmitters have a power switch to turn them on and an LED to show their power status.
Advanced transmitter features The majority of us use the bundled transmitter that comes with our models, but there are advantages beyond custom batteries and improved comfort in purchasing a higher-end transmitter from the likes of Spektrum.
Multi model support Professional transmitters often feature profiles, allowing you to bind the controller to multiple models , each with their own setup and refinements. RC Fail safe More relevant to the receiver than the transmitter, many models feature a ' fail safe ' fall-back mode. Stay Informed!
