serendip Posted June 22, 2019 Share Posted June 22, 2019 Hi all, I'm building the excellent GWH F-15I. My question is on some 15's the actuators are visible but on others they're sheathed (if you know what I mean). My question is should I be using the sheathed nozzles as supplied in the kit or should I buy aftermarket with the actuators laid bare? If so who does a good pair? Hope my question makes sense and many thanks, Marc. Quote Link to post Share on other sites
arnobiz Posted June 22, 2019 Share Posted June 22, 2019 F-15Is retain the feathers, if you want extra detail you can use Aires exhausts combined with the GWH feathers it works well with a bit of external thinning of the Aires parts (invisible once the feathers are on top): Quote Link to post Share on other sites
Mstor Posted June 22, 2019 Share Posted June 22, 2019 BTW, you posted this in the archives section, where old posts go to spend a quiet retirement. You'll get more visibility if you post one level up in the regular Jet Modeling forum. But, arnobiz pretty much answered your question. Yes, the F-15Is retained the "turkey feathers".

serendip Posted June 22, 2019 Author Share Posted June 22, 2019 Thank you both guys, and seeing as the question seems to be answered I'll leave this one in retirement. Quote Link to post Share on other sites
serendip Posted June 22, 2019 Author Share Posted June 22, 2019 And out of interest, why do some have the fairings (the turkey feathers I guess) and others not - no aerodynamic advantage? Thanks, Marc. Quote Link to post Share on other sites
Dave Williams Posted June 23, 2019 Share Posted June 23, 2019 The original turkey feathers were a bit maintenance intensive, and also sometimes fell off. US Eagles eventually removed them, figuring that the maintenance advantage and weight savings of removing them outweighed the reduced drag of keeping them. Plus, US aircraft normally have plenty of tanker support, so a bit more drag isn’t a problem. The Israelis kept the turkey feathers on their A-D models for quite a bit longer than the US, but eventually also started removing them. The F-15Is all retain the turkey feathers, which are made of carbon fiber, rather than the metal of the originals. Quote Link to post Share on other sites
