I dont need to analyze any data I just needed a decoder with failsafe I can set; and your solution is the only one in the world at the moment that does that thing in specific way and can be set for any channel seperately to a different value;
For now I will try with 4017 and this failsafe should do the job:
RC-CAM Projects: RCFS-V2, Advanced Radio Control Fail-Safe it has 3 modes and can be preset to any servo positioon with a click of a button!
