At present, most of our drones have four types of receiver options. So how to choose the appropriate receiver according to your needs and adaptability is very important, and it is also a point that many novice customers are confused about. 

This tutorial will introduce in detail the differences and characteristics of different receiver versions, helping you quickly select the appropriate receiver version and start your shopping and flying journey.


First of all, the most important thing is: Receiver and the remote controller must be compatible with the same protocol and have the same firmware version in order to be able to bind together.

At present, most of our drones have 4 types of receiver options. 

1. I use DJI FPV Remote Controller 2/3 --HD/Without RX (PNP) --Analog

2. ELRS 2.4GHz (True Diversity) RX Option 

3. ELRS 868/900MHz (True Diversity) RX Option 

4. TBS Crossfire (Diversity) RX Option


So how to choose the appropriate receiver version according to your needs? Let's go ahead!


1.1 I use DJI FPV Remote Controller 2/3----Compatible with SBUS protocol
For compatibility among different Air Units, DJI remote controllers and DJI goggles versions, please refer to the Compatibility Table, or consult our customer online service

1.2. Without RX (PNP) For Analog Drone
Customers are required to install the receiver themselves after receiving the drone and choose a remote control that is consistent with the receiver’s protocol.


2. ELRS 2.4GHz (True Diversity) RX Option--Compatible with ELRS 2.4 protocol
If you choose ELRS 2.4GHz (True Diversity) RX option, a remote controller compatible with the ELRS 2.4 protocol is required, such as our Commando 8 Radio Transmitter ELRS V2 - ELRS 2.4G RF 500mW version/ Commando 8 Lite- ELRS 2.4G RF 100mW
or other brands of remote controllers compatible with the ELRS 2.4 protocol

3. ELRS 868/900MHz (True Diversity) RX Option--Compatible with ELRS 868/900 protocol 
If you choose ELRS 868/900 (True Diversity) RX option, a remote controller compatible with the ELRS 868/900 protocol is required, such as our Commando 8 Radio Transmitter ELRS V2 - ELRS 868/900MHz RF 1000mW version or other brands of remote controllers compatible with ELRS 868/900 protocol

FAQ

1) What is the difference between ELRS 2.4GHz and ELRS 900MHz RX options?


Both ELRS have their own advantages.

 
ELRS 2.4GHz 500mW supports an ultra-high refresh rate of 500 Hz, and the antenna is small in size, suitable for track racing drone and small lap drone.

ELRS 900MHz 1W has a higher penetration rate, suitable for freestyle flying, long-range flight or flight under complex conditions

If you're not sure what to get, please check out the official ELRS Long Range Competition to see what has been achieved. https://www.expresslrs.org/2.0/info/long-range/



2) Why doesn’t Commando 8 Lite have an ELRS 900MHz option?


The Commando 8 Lite only has 2.4GHz 100mW, which is mainly designed for novices to meet the needs of freestyle.

ELRS 2.4 has a higher refresh rate and stronger anti-interference ability, which can meet the needs of novices, so Commando 8 Lite only offers ELRS 2.4 as an option.



3) Can the ELRS 2.4GHz (868/900MHz) receiver be used with the ELRS 868/900MHz (ELRS 2.4GHz) remote control?  


No, ELRS (ExpressLRS) supports multiple frequency bands, including 2.4GHz and 868/900MHz. However, the receivers and remote controls for 2.4GHz and 868/900MHz are devices of different frequency bands and cannot be directly paired with each other. 

If you have an ELRS 2.4GHz remote control, it is only compatible with the ELRS 2.4GHz receiver. Similarly, the ELRS 868/900MHz remote control will only be compatible with the ELRS 868/900MHz receiver. 

Therefore, you need to ensure that both the remote control and receiver operate on the same frequency band to function properly.




4. TBS Crossfire (True Diversity) RX Option--Compatible with CRSF protocol 
If you choose TBS Crossfire (True Diversity RX option, a remote controller compatible with CRSF protocol is required, such as TBS's Tango 2 or a remote controller with CROSSFIRE NANO TX installed to make it compatible with CRSF protocol

Note: If you need to achieve a more stable remote control distance, it is recommended to use the ELRS protocol or TBS remote control to achieve long-range flight!

In short, choosing the receiver and remote control with the corresponding protocol according to your needs is an important part of achieving effective shopping.

If you just got into this hobby, please look into some videos on our official YouTube or other online resources.

There's a lot to learn and understand, but it's totally worth it!
