I finally found a FC board that worked out of the package for my QX90, with the integrated Spektrum RX. It works fine with out flash BF or CF firmware, although I did try doing both of these without success. For both CF & BF I only receive errors trying to connect to flash the firmware, not sure why, so I let it as is.

It flies well. I temporarily set it on Nano QX frame with MMW Fast motor. Binding with Spectrum DX6i is fine. Cleanflight works well and I should configure it for better stability and quicker yaw.
