Is EastSoft HW2181 a compatible chip?

Hello forum. First post here.
It has been suggested to me to ask my question here, in these forums, regarding my hardware.

My main question is:
Is the chip EastSoft HW2181 compatible in any capacity with the software provided here?

More in depth:
My toy RC quadcopter is from Lidl: PowerRC Quadrocopter

What I have tried so far:
I have a RC radio FlySky fs i6x
Purchased the iRangeX iRX6 Multiprotocol TX Module for Flysky FS-i6 i6x TransmitteriRangeX in hopes that it will work with the toy quadcopter.
Unfortunately none of the protocols of the module bind to the quadcopter.
Two of protocol selections did not produce any led flashing on the module, however I am not sure if it is working as intended, faulty firmware, and/or unrelated to this forum at all.
The full list of models/protocols of the iRangeX module is available in PDF from here .

The toy has three fly speeds, slow-normal-aggressive. It is able to do flips. LED lights are toggle-able. The remote control has a similar EastSoft chip - HW2171
Extra features (if available on aircraft):
Channel 5: led light, 3 pos. rate on CX-10 and FQ777-124, H7, inverted flight on H101
Channel 6: flip control

Personal Speculations:
Eva2king Drone X5c appears to have the same chip on the board. The quadcopter shell has a very similar look to SYMA and obviously the model X5C.
elmsem website also has this SYMA drone claiming they use HW2181+HW2171 chips
Michael Melchior's BLOG describes reverse engineering a quadcopter drone from LIDL, however it appears to be different to mine.


Ideally I wanted to use my existing FlySky fs-i6x controller and the iRangeX iRX6 module to control the quadcopter to have "more resolution on the sticks" when flying it.
Reading up on Deviation's wiki and tutorials I understand that this forum is more dedicated to Walkera Devo® series RC Transmitters.
Neither the drone model, nor the chip appears to be on Supported Models and/or Supported Protocols.
The least I could do is show compatibility interest for my model/chip.

Any help is very much appreciated.

It's not supported, I might have a look into it someday but don't hold your breath ;)

Hello Mr.Rossos, Mr.goebish, and forum.
I found a new Toy using this chip. (EastSoft Transmitterr:HW2171 Reciever:HW2181)
I hope that this DeviationTX will support it.

Seems those chips (HW2171) are used in a few 1/24 rc crawlers too. RGT Adventurer v2 & Element RC Enduro 24 & HobbyPlus/URUAV/Amewi/Amexrock CR-24

The 1/76 TurboRacing mini car also seems to be using this chip (HW2181B to be precise, however I suspect this detail is irrelevant)

Here's the datasheet, but it does not seem to easily say anything about compatibility with other chips.

I (might) have access to a SDR device and if I find some useful guidance regarding analyzing it off the air, I'd be curious to try. Anyone knows a good pointer to a tutorial (by "tutorial" here I mean something that suggests tools/ways for analyzing a (most probably) frequency-hopping protocol).

You can use translators like deepl.com to translate from china to english. I just tried and i think it provides a good traduction.
