New protocol for FX070 and FX071 alternate board

Has anyone looked into the protocol used for the alternate controller board model labeled WJ-070RX-2,4GHz, shipped for the Feilun FX070C or FX071? It doesn't bind to any current protocol residing on the Jumper T8SG or the original transmitter shipped with the 'KN' version FX070C. The KN Feilun option protocol works well with the 'KN' version of the controller. The transceiver chip used in the WJ version is the XN297LBW while the 'KN' version uses the BK2423 chip. I don't have a transmitter that binds nor experience or a logic analyzer to capture the binding code sequence or anything else. Is anybody interested in looking into this? There are quite a few users of Feilun helis out there. Any help would be greatly appreciated.

Thanks.

Hi
I'm new in the fora but I have the same problem any ideas how to bind the new board. Is it different protocol?

I will post you a deviation build to dump packet data, so we can maybe get some more info. But you will need a stock transmitter for that (maybe copterfan has one?). What deviation tx do you have?

Sorry, I don't have the new original transmitter. If anyone have it I would apreciate an attempt to capture the protocol
