R9 Stab Reciver / Stabiliser anyone use?

[Ziov1]

Has anyone ever used the R9 Stab, I'm new to doing rc build's I bought the R9 module and the R9 Stab Reciver for my flying wing but I'm unable to find much details about the stab reciver everything I can find online is for the R9 reciver not the stab version with gyro, auto level, stabilisation etc.

Anyone know how to update firmware on the R9 Stab Reciver? It says OTA but instructions only say to use an s port USB adapter. Also can't find any specific to the R9 all seem to say r6 and r8 will it work with an r9?
