Ben Brown Posted May 7, 2021 Share Posted May 7, 2021 I'm looking at the parts diagram for the Z-M F-4E. On Sprue A, Parts A6 and A7 are not used. Are these wider (they would extend farther aft) versions of A13 and A14, the sheet metal surrounds for the afterburners? If so, would anyone be interested in selling them to me? I'm in the US and will happily pay a fair price and shipping. Thanks! Ben Quote Link to post Share on other sites
Piker38 Posted May 7, 2021 Share Posted May 7, 2021 I'm looking at my E... those parts are identical in size, just marked for more, narrower segments... maybe for a later version of J79 (?) Quote Link to post Share on other sites
Ben Brown Posted May 8, 2021 Author Share Posted May 8, 2021 (edited) Thanks! I have found a set, assuming they're for the short nozzle -15 engines. This area extended farther aft than on the long nozzle-equipped jets. If I've guessed wrong, I'll just contact Z-M to order the appropriate parts from their F-4C/D kits, because I'm too lazy to modify kit parts. I should have provided this link to Tommy Thomason's blog, to make what I'm looking for clearer: F-4 J-79 engines Ben Edited May 8, 2021 by Ben Brown Quote Link to post Share on other sites
JeffreyK Posted May 9, 2021 Share Posted May 9, 2021 The two types of exhaust shrouds in the kit are both for the -17 engines as in the F-4E (shrouds for -8 and -15 engines wouldn't have the crescent shaped cut back and go straight down from the vent louvres). The difference is that the JASDF (Mitsubishi built) used a modified shroud with cuts at short intervals as opposed to the original continuous strip of metal. Most likely they found this to perform better under heating/cooling conditions or perhaps were able to use a lighter or cheaper material than the original?

Ben Brown Posted May 9, 2021 Author Share Posted May 9, 2021 Ah, thanks for the explanation, Jeffrey! I guess I’ll be ordering the appropriate sprue from Z-M for my Blue Angels project, then. Ben Quote Link to post Share on other sites

That nicely explains the difference. Thanks. BTW: Has anyone else found these parts difficult to install properly ? Mine just do not want to sit right. Quote Link to post Share on other sites
