As I’ve stated before the core architecture of the engine is based on the legacy design. Perhaps the use of “clone” was a bit facetious, but it got the intended response. However, never stated these were “minor” upgrades as dropping the N1 gearbox I would consider a major upgrade. Regardless, its my understanding the current issue is not design related but involves transferring the design to the in-house manufacture equipment which is not yielding the predicted finished results.
