Good designs, manufacture and testing ensure reliability; I think redundancy is a different topic.
FWIW I forgot I left an RF modem on, it's been it is' test harness for a week.
It's a DNT900P - just checked and it seems fine. Might try leaving my Umarim on for a week and report back.

Dear Refik,at the moment I think there is no implementation which would allow a redundant setup.When you think about it there are some problems like how to connect the servos and how to do the switching (how do you decide which autopilot is "correct" at a given moment).You would need 3 systems and a voting/switching system.This will make your whole system so complex that the chance for a failure probably rises...Normally Taparazzi systems are very robust and reliable. So I would go for one of the up to date systems (depending on your setup) like LISA or Umarim in standard configuration and do a lot of testing before the long duration attempt. Then monitor the values closely during flight and stop if anomalies occur.CheersMarc
