Lian Sheng LS-124, LS111

Hi does anyone know if the Lian Sheng LS-124/LS-111 protocol is deviatable and if so if anyone has given a stab at it? They're great little quads with super fast yaw rates but crippled by the controllers.

I could take some pictures of the inside of the controller if anyone is interested. I couldn't tell what chip they have as it's under a dot but it looks like it's probably a common one as it's a little board soldered on (pins CE, CSN, CSK and MISO)

Thanks:)

A picture is always helpful.

Give the YD717 protocol a try, as well as its symax2 and nihui options. The 124 looks similar to the yd717, and the yd717 radio sounds like what you've described.

@Hex , if you want some homeworks, I can sniff many new SPI data based on nRF24L01 or compatibles models : The new H9D, HM1315 for example ....

LOL well there's not much good flying weather lately so I'm not having to spend so much time on crash repair

Any of the ones you have that are popular with Deviation users would probably be worthwhile. Or several models supported by one protocol. Don't want to fill the protocol menu with ones that never get used.

If I'm not wrong, the LS-111, LS-112 and LS-124 uses XN297, so could be the first XN297 model Hacked

I went through and tried all the protocols I could including YD717 (I only have the nRF24L01 board) I tried SymaX but didn`t see a SymaX2 in my list.
OK Here's some pics of the board (although Durete thinks it uses the XN297 chip so maybe they won't be useful. Sorry probably overkill

Interesting pics. Looks like the board can take an alternate radio module. Wonder if the label in the second pic is "NRF" under the white stuff?

I didn't find any XN297 modules on ebay or amazon. It would be interesting to know if it's compatible with the current deviation nRF protocols. The cx10 code might also work with the XN297. But a volunteer would have to remove a module from a stock tx to install in their devo It would install just like an nRF24L01...

OK I pulled apart my ls111 controller because I'm ok with sacrificing that one anyway and unfortunately it doesn't have a breakout board. I was however able to confirm that it is a XN297 chip. (XN297 1428 printed on it)

I just looked on the data sheets and since hey are pin compatible couldn't I buy a nRF24L01 board and remove the chip and replace it with a XN297 chip. I could get the signal amp if I did that too. They both are a QFN20 so it shouldn't be that hard (although small).

Thoughts?

Would be nice to fly the Lian Cheng nano quad with the Devo7E. Any future plans on this?

It would be nice..

maybe someone in this thread can help...

I am also interested in this. at list i think i have LS-112 quad.
LIAN SHENG is written on the box, it looks like CX-10 (even remote) and when i open the board i see LS-111TX written on the board

however the transmitter board is not the same as the one on the pictures previous in this thread. the main chip is different (20-pin as oposed to 24-pin in the previous post)
there is nothing written on it ... but there is the same XN297 transmitter.

is there any support for XN297 in deviationTX (any protocols ? ) if i understand correctly this chip can be emulated using nrf24l01

any idea what would be the chip in the transmitter ? (where is its SPI port ? :\ )
