I have noticed that from 2016 onward many F/A-18E/Fs have their exhaust nozzle segments ("turkey feathers" in simple words) replaced with a newer version. The original segments didn't have the cut at the end. Now the nozzle looks almost identical to that of the F404 engine used on the F/A-18C/Ds. Its very common to see one exhaust with the cuts and the other one without them on the same jet, even on the same nozzle some segments are the older ones and some are new with the cuts! Now that would be interesting to replicate on a model, I thought to use one exhaust nozzle from the Aires Super Hornet and the other one from the Legacy Hornet. Any one has more information on this development on the F414 engine?
