RF module for spectrum?

[erhard52]

ok i was able to bind the radiomaster R88 to the TX16S (now that should not be a surprise) but is also was able to bind the SPM4651T.
i have not modified the x10+ yet to understand the spektrum protocol

i also fixed the conversion to the mode 1 after opening up the back plate - kind of sad that they misplaced the opening holes. funny under one stick they have the misplaced holes and under the other stick they have no holes at all but one needs to modify the motion friction on both sticks - go figure. maybe i am the only one in the world need to do that
