      Hello,

      I am currently building a 767-400ER kit. I will try post photos even though it is in early stage.

      Right now I am scratchbuilding the engines as the ones provided in the Zvezda kit are of the earlier slightly smaller and subtly differently shaped variant.

      I was wondering if any of you had the Brengun 747-400 CF6-80C2 exhaust cones ? On the photos they look nice but I can never trust these internet photos, often I find out they are edited to make the parts or sprues look better.

      Thank you for your advices.

      Cheers, Stephane

      Hello,

      Ok, I could not wait so I ordered on the 24th, delivered this morning, this is what I call speedy !

      Wether the master was 3D printed or not, the finish is superb, displaying 2 circumferential finely recessed lines, simplified but still nice precooler outlet louvres, a fine exhaust sleeve edge, a nicely defined hollowed-out exhaust spike and overall no 3D printing layers at all.







      This very part features an air bubble right at the exhaust spike end, I will probably cut it off and replace it with some metal tube, no big deal. The 3 other parts included in the set are defect-free.

      It is designed for the Revell 747-400 but will of course suit any CF6-80C2 powered 767 kit since the engine model is the same.

      Cheers, Stephane

      Wow! Looks spot on with the real thing! Looking forward to seeing how you get on in the end!

      It's common practice to re-work 3-D printed parts patterns before making the silicone molds. Light scraping and sanding, followed by a coat of primer in SOP. It's always best to get early castings of resin parts, since mold degradation is swift with silicone, and deep fingers, and deep, fine scribing, are the first to wear out, with the castings slowly losing definition through the sequential casting process.

      Hello Jesse,

      Thank you ! Yes these parts are nice and IMHO cheap.

      I will post more photos tomorrow, the right fuselage is already extended and glued, the left fuselage is about to be done, APU intake and RAT well are hollowed-out. The most difficult part will be the slats and flaps in landing configuration.

      Cheers, Stephane

      Hello Dana,

      Thank you for the info , I bought 2 sets just in case but will certainly order more next month for my 747-400.

      Boy is resin casting a science . Years ago I wanted to give it a try but I often read that casting without the vacuum technology gives mediocre results.

      Cheers, Stephane

      Keep us posted!

      Are those white pieces guides for the fuselage extension that we can see? And are they on the outside of the fuselage? Iím going to do this conversion (someday) so Iíll be interested to watch yours!

      Hello,

      Yes they serve to align the fuselage sections, I glued them inside and outside, it helps me prevent the use of filler in case of misalignement... boy I hate using filler.

      Cheers, Stephane

      Will you remove them later?
