Spektrum DX8 vs DX9: Detailed Discussion

Let’s be familiar with the few similarities of both transmitter models first.

Channels and Bandwidth

Both Spektrum DX8 and DX9 have a 2.4Ghz frequency bandwidth signal. However, the DX9 has a slight edge over its predecessor for its one extra channel. The DX9 has 9 channels, giving the users more freedom over the controls.

The Dx8 and DX9 both support all 4 presets. Airplane, Multirotor, Helicopter, and Sailplane. Thus, allowing the user to control almost any flying vehicle.

Backward Compatibility 

Backward compatibility allows the user to use a controller with old receivers. It saves the user the time and cost of buying a new receiver.

DX8 and DX9 both use DSMX and DSM2 quality receivers from Spektrum. While DSMX offers a much stronger signal, the DSM2 receiver is a good option for money-saving.

However, the DSM2 receiver is not sold in Europe. Thus, leaving Europeans with only the option to use DSMX receivers.

Now that we are on the topic of receivers, here are some of our top picks-

Product 1
Product 2

Programmable Mixes And Antennas

The DX9 is more versatile and holds more potential thanks to its 10 programmable mixes. The DX8 on the other hand only has 6 programmable mixes, making it less flexible.

To top that off, the DX9 also boasts dual antennas over DX8’s single antenna. The dual antennas improve signal quality and help with polarization.

Having two antennas increases the overall reliability of the signal. But it doesn’t increase the signal range.

Flight Modes 

The DX9 offers 5 flight modes to the user, again, one more than the DX8. This allows the user to explore one additional flight mode. This can lead to up to 10 flight modes if you are using the Sailplane preset.

Model Memory

DX8 also takes a huge beating to DX9 when it comes to model memory. The DX9’s superior 250 model memory outshines DX8’s 30 model memory in every possible way. 

This huge capacity means that the transmitter doesn’t need to shuffle SD card and transmitter memory. It also made navigating through the model menu easier. 

Voice Alert System

The days of constant vibrating to alert users are over with the introduction of voice-alert systems. This new feature helps you to keep a tab on important functions while flying. It allows you to program voice alerts.

This can help you call out the flight mode you have chosen, or seek reports. The DX9 will also notify you if an alarm goes off. It’s a handy feature to avoid future physical problems in your Spektrum DX9.

The voice alert option is available in English, Italian, Spanish, French, and German.

Forward Programming

It’s a new innovative software feature added in DX9. This feature will let you program new generations of Spektrum components directly through DX9. It also unlocks a whole new horizon for DX9 future updates.

Wireless Trainer Link

It is now possible for DX9 users to link up wirelessly with other Spektrum transmitters. The DX9 won’t have to rebind again if bound with another transmitter. It also comes with a trainer cord jack if an old-school user wants physical connections.

This feature makes Buddy boxing easier than ever.

It allows you to assign gimbal functions to a second camera transmitter. With this, you and your friend can control the camera and flight of the drone separately.

Spektrum DX8 vs DX9: Verdict

The Spektrum DX9 is the clear winner here. 

It has a number of new features and also surpasses the DX8 in existing features.

However, its expensive price might be too much for most regular users. Besides, the new features in DX9 do not bring any major upgrades. With 180 USD less, you can get almost the same performance in DX8.

For beginners and regular users, DX8 will be the best option. It still offers a wide range of presets and functionality. But if you are willing to spend those extra bucks, DX9 is the transmitter for you. 


Questions: What receivers work with Spektrum DX9?

Answers: The DSMX and DSM2 protocols are used by the Spektrum receivers. However, DSM2 is not available for users in Europe.

Questions: Is Spektrum DSMX compatible with DSM2?

Answers: Yes. DSMX receivers are backward compatible with DSM2, while the DSM2 is forward compatible with DSMX.

Questions: What batteries are supported by Spektrum DX9?

Answers: The Spektrum DX9 comes with an included 2-cell Li-ion battery at a charge rate of 200 mAh. It requires 12-15 hours to fully charge the batteries the first time you use them.


With that, we have discussed everything you need to know on DX8 vs DX9.

Hopefully, you will be able to choose the better transmitter that suits your RC experience.
