I am building an RC aircraft, 10kg weight range.
It is supposed to perform long flights (20km+), so reliability is my main concern, mainly on servos controlling Flight control surfaces.
How reliability is maintained on RC planes?
I am afraid if any flight control surface servo would be jammed while manouvering, crash would be quite horrible 🙂

Get the most reliable servos (and other gear) you can in the first place and over spec the servos and their attachments greatly so any mechanical stickyness can be forced out of the way.
If you are still not convinced that you have enough reliability, then look into how commercial airliners get higher reliability:
In the end I doubt any of those enhancements would do a lot of good in practice as all the redundancy will also add complexity and thus new sources of errors, just look at all the problems Airbus had getting their flight systems debugged.
... but I bet a whole lot of fun could be had building all of that redundancy.
