1.1  4-channel Flysky Transmitters

FlySky sells 4-channel transmitters, but while a 4-channel TX is adequate for simple RC cars, boats, and planes, a mini quad requires 6 or more channels.

Channels 1–4 are used to control the actual movement of the craft, while the remaining channels are delegated to the radio's switches and pots (potentiometers) and are regarded as "Auxiliary Channels," denoted by the letters AUX 1, AUX 2, and so on.

Aux channels on a quadcopter can be used to activate different flight modes and control various peripherals such as a lost model buzzer and LED light. With new technology being released regularly, the number of functions and peripherals that we can control from the transmitter grows by the day.

Realistically, if you only have 6 channels available, you will quickly feel limited, so we have only included TXs with 6 or more channels.

1.2 Essential Features of Flysky Receivers 


I believe that telemetry was an afterthought for FlySky, and given that most newer FCs come with an integrated OSD, who can blame them if they are focusing sales on the FPV market? In reality, telemetry is one of the 'bells and whistles' I mentioned earlier, and it is by no means required for the beginner.


As you can see, there are some sacrifices that must be made when using a FlySky RX to ensure that you have an operational failsafe. Failsafe is probably not as important as the telemetry in an indoor model or a micro you use in the garden, but it is far more important. For some reason, the best RX FlySky makes for larger models (the FS-X6B) only offers a failsafe on the older PWM protocol, which is in my opinion absurd.

As you can see, failsafe is not always available over specific protocols, depending on the RX. Failsafe is far more important than telemetry because it reduces the possibility of unexpected behavior in the event that the RX signal is lost. Take the time to ensure you're using a failsafe protocol!

Ⅱ RF Transmitter vs RC Transmitter

2.1 What is RF Transmitter?

An RF transmitter is a type of electronic device that uses an antenna to convert analog signals to digital signals. They have an embedded storage memory that aids in the storage of information, which is then converted by an RF receiver as required by the user. RF transmitters operate at various frequencies, allowing signals to be transmitted at the desired frequency range. They are primarily used in a variety of applications ranging from electronic toys to telecommunication devices and satellites.

2.2 What is RC Transmitter  ?

2.4GHz radio control transmitters (TX) for all RC applications. Stick and wheel transmitters are available from Etronix and are suitable for use in automobiles, aircraft, boats, and drones.

2.3 Differences between RC and RF Transmitters 

RC stands for “radio control”.

RF stands for “radio frequency”.

A radio frequency is used by radio control transmitters to transmit a signal. Radio frequency is used by TV and radio stations to transmit a different type of signal.

Radio frequency is a very broad term that refers to electromagnetic signals with frequencies ranging from 100kHz to 100GHz. Radio control is a subset of radio frequency usage.

Ⅲ Key Points of RC/ RF Transmitter and Receiver

3.1 How to Pair your RC Transmitter and Receiver?

Most modern RCs use 2.4 GHz TX and RX that must be paired in the same way that a Bluetooth device is paired with a computer or phone. The RX  has a couple of pins that are connected by a special binding plug. A bind button or switch is located somewhere in the TX. By shorting two pins, you can activate the RX while the TX is in bind mode. When the bind is complete, the LED will usually flash quickly and then glow steadily, and the RX will respond to stick motions. The bind plug is then removed from the RX, and the RX will begin listening to your receiver once it detects its unique transmitting protocol.When the TX is turned on, it will first listen for an available channel before transmitting on it, while the RX will scan channels until it hears the transmitter to which it has been bound. There is usually a brief "boot up" period before the link is established, lasting about a second. Although it is still legal to use old equipment such as crystals and frequency control boards, they are largely obsolete.

3.2 How do You Increase the Range of an RF Transmitter and Receiver?

Several ways are available.

  1. Increase the power of the transmitter. This is not always legal.
  2. Utilize a single sideband (SSB) AM modulation scheme to direct more power to a transmitter signal (legally).
  3. For the transmitter and receiver, use a lower frequency carrier. Longer wavelengths frequently have a greater range than higher frequencies.
  4. Use a higher modulation percentage to produce a signal that is easier to decode at the receiver.
  5. Tune the transmitter antenna if it is not already well-tuned. Use a better ground plane if possible, or place the transmitter closer to a natural ground plane.
  6. Raise the transmitter antenna's height above the ground.
  7. Utilize a directional antenna with gain pointing in the direction(s) of the intended receivers.
  8. Extend the range beyond-line-of-sight by utilizing ionosphere reflections. This is not always reliable because it is affected by natural ionosphere changes.
  9. Utilize a repeater at a point halfway between the transmitter and the receiver. This could be anywhere, including a mobile device, a mountain top, a tall building, or even a satellite.
  10. Raise the height of the receiver antenna above the ground.
  11. Install a better ground plane or place the transmitter near a natural ground plane, such as a lake.
  12. Use a directional receiver antenna that is pointed in the direction of the desired transmitter and is tuned to the correct frequency.
  13. Use a receiver with a higher gain, lower noise, and greater sensitivity.
  14. Use a digital data encoding strategy with data correction capability, a more robust, slower transmission data encoding scheme with multiple, redundant transmissions, and a receiver capable of decoding and error-correcting that data.
  15. Utilize multi-band transmission to compensate for poor radio propagation conditions.

3.3 How do RF Receivers Synchronize on a Transmitter's Signal?

Synchronization is usually accomplished in stages.

Step 1

Align the frequencies of the transmitter and receiver. In the days before synthesized oscillators, improving frequency stability required some serious engineering. Typically, the last resort was some form of automatic frequency control, or AFC, which used a pilot carrier that was transmitted alongside the actual information carrier.

Step 2

Advances in frequency control enabled the AFC to be removed from many applications. Today, most frequency error correction is done in the demodulator circuit.

Step 3

Demodulate the information bits carried by the modulated wave. This results in demodulated data, which can then be analyzed for patterns or embedded clock information.

This data is used to adjust the phase of a locally generated clock signal so that it corresponds to the data elements received.

In some implementations, clock recovery information is embedded in the data itself, whereas in others, special patterns or bit sequences are dedicated to clock recovery.

Step 4 Properly align the data streams with the demodulator so that the actual information can be retrieved, a process known as "data" or "frame" synchronism.


3.4 How to Bind RC Transmitter and Receiver ?

Most RC transmitter manufacturers provide pre-programmed transmitters for their respective receivers. However, if you need to replace the components, you can do so by following these steps. The tools you'll need include an accessible receiver, a charged battery in the model, and charged batteries in the transmitter.

Syncro System (Kyosho)

The Syncro system is commonly used in a variety of models such as the Fazer Rage, Fazer Tl drift car, Outlaw Rampage, and many others. The binding tick requires you to hold down the bind button while powering up the model.

You'll notice the transmitter LED flashing quickly. Then, before releasing the bind button, turn on the transmitter. The receiver LED will then re-light to ensure that the process is complete.

TQi Top Qualifier (Traxxas)

Another ultra-ergonomic high-performance system was found on the Merc G500. Roveris Traxas' radio is TEXAland Roveris Traxas. To rebind this radio, press and hold the red setbutton on the top of the RC transmitter while turning it on; the led should gradually flash red.

You can seat the release button at the same time. Press and hold the link button on the receiver end while turning on the speed controller. Finally, when it is powered up, you can let go of it. You can take it for granted if you notice the receiver and transmitter lights turn green.

Tactic TTX300 Binding (Axial)

This transmitter and receiver system is found on the RTR Axial SCX10il. To bind this, turn on both the receiver and the transmitter, as well as the RC car.

Then, on the receiver's box, press and hold the link button. You must press and hold it until it turns red, just before it turns off. Finally, its receiver LED will flash once before returning to a steady state.

3.5 8 Tips for Easier RC Transmitter Control 

Although most transmitters provide adequate grip and comfort, there are a few tricks you can use to improve them. Improving grip can improve how well you drive your vehicle, which is a definite advantage if you like to compete. Here are a few RC Transmitter Control  tricks that you can use to gain an advantage over your competition.


Tennis Racket Grip Tape  Wrapping the transmitter's grip with tennis racket grip tape will help wick away any moisture created by your hand, reducing the the'slip' factor. As a result, the transmitter is easier to hold without fear of dropping it. You won't have to grip as tightly, which will reduce hand fatigue. Furthermore, because the tape is thin, it will not change the size of the transmitter grip. This is a plus if you like the size and feel of the stock transmitter in your hand. You can also choose from a variety of colors for the grip tape, which will help you identify your radio.
Steering wheel change Aftermarket steering wheels are available from companies such as Duratrax, Hot Racing, and Dynamite if your steering wheel is worn or you want to try something different. Not all foam is the same, and you may find one that suits you better.
Improved Grip There are also steering wheel grips that can be added to improve control and reduce fatigue. Pro Grips from Xtreme Racing are designed to fit over your existing steering wheel. The scallop shape gives your fingers a place to rest, and the grips don't require glue to stay in place.
Drop Down Kit  The manufacturer of your transmitter may offer a drop down steering wheel kit. These kits lower the steering wheel so that your hands are in line with each other, which may be a more comfortable position for you.
Trigger Tricks 

1.I've discovered that some triggers are so smooth that your finger can slip off of them. Fix this with a wrap of racket grip tape.

2. A length of fuel tubing is an easy fix for triggers that don't provide a tight feel for your finger, which can impair braking responsiveness. To help close the opening for your finger, slide the fuel tubing over the forward section of the trigger. This trick will also increase the friction on your finger.

Self-adhesive Foam

If you want to make the grip larger and/or contour it to your hand, some self-adhesive foam can help. It may take some trial and error to get it exactly how you want it, but it is worth the time to get it right. Once in place, cover it with grip tape to make it more secure.

Optional Grips

If you read the instruction manual for your transmitter, you will most likely discover that the manufacturer provides optional transmitter grips. They are typically available in larger or smaller sizes than stock and are simple to install on the transmitter.

cost effective and overall great product. The transmitter feels a little cheap, but its performance works just as advertised. ... Overall, I say this product is a good buy. It's simple and relatively cheap (compared to other models), but performs great!

2. Can you use any transmitter with any RC car?

Yes, RC transmitters and receivers are interchangeable, so that you can use transmitters and receivers of different brands, and they will work perfectly.

3. Is FlySky and Frsky the same?

In my view, the components of the frsky stations have a much higher quality than the flysky ones. ... But if yours is going to fly more continuously, you are looking for reliability because you already have a more serious and more expensive model, I recommend that you acquire a Horus or taranis type frsky station.

4. What is the range of a 2.4 Ghz RC transmitter?

about 300 feet

The 2.4GHz version of the HumRC Series is about 300 feet (90m) for remote control applications.

5. Are FlySky and Spektrum compatible?

But Spektrum transmitters cannot talk to FlySky receivers - ever. ... But Spektrum transmitters cannot talk to FlySky receivers - ever. Spektrum transmitters require receivers that use the DSMX or DSM2 algorithms. You need the Spektrum AR610 receiver (or equivalent) in order to bind with your Spektrum DX6 transmitter.

6. Is FlySky compatible with DSMX?

You would need to put a Spektrum compatible RF module in the FlySky transmitter. ... If the flysky uses the spektrum dsm2/dsmx then yes.

7. Does FlySky have telemetry?

Spare receiver for the FlySky i6 Transmitter. ... Voltage telemetry built in when paired with the i6 transmitter. This receiver features dual antennas for optimal performance and no fear of interference.

8. Is Flysky GT5 waterproof?

The gyro function is surprisingly valuable in both and you can get a bunch on amazon real cheap. however, I recommend using some conformal coating or corrosion -x as they are not waterproof. I use the FS-GT5 with the FS-BS6 receivers and they work great in my cars and in my boat.

9. Can you bind any transmitter to any receiver?

You can use a transmitter with any receiver. BUT you have to have a way of changing the antenna when you transmit. There are antenna relays for this purpose that will automatically make the change for you. The power of the transmitter would quickly destroy your receiver.
