I don't think anyone is claiming the S-97 should be immune to anything. But let's not pretend this is an isolated "slip" in a vacuum.
This is a discussion of a suspicious delay of a flight test programme relative to its stated objectives, its immediate predecessor X2, in addition to a publicly announced delay of a growth version of the same technology with SB1....all under the guise from the manufacturer that there are no technical issues (or more to the point, no scaling issues).
Comparisons to the V-22 program of record are not germane to discussion for myriad reasons.
