a4s4eva Posted October 17, 2015 Share Posted October 17, 2015 (edited) I'm building a F-4EJ and decided to use a set of True Details intake, no 48522. I know they aren't the correct full internal length but externally they are significantly different in length as well. TD is the top, Hasegawa plastic is the bottom Any idea whats up here? Are these not F-4E intakes but F-4B/C? Edited October 17, 2015 by a4s4eva Quote Link to post Share on other sites
Jennings Posted October 17, 2015 Share Posted October 17, 2015 Other than the prototypes, all J79 powered F-4s have exactly the same intakes. One or both of those is incorrect... Quote Link to post Share on other sites
MoFo Posted October 17, 2015 Share Posted October 17, 2015 Resin shrinkage. Whoever's doing casting for True Details/Squadron has used the wrong resin. There are low shrinkage resins out there, which will only shrink by a percentage or two, but obviously whatever that was cast in is a lot worse. :( Probably doesn't help that the part is fairly dense, so there's more mass to deal with. Nothing you can really do except try to get a replacement and hope that one's better, although I'd be surprised if things varied much from casting to casting. Only other option would be to try to 'nest' the resin intake inside the kit part. If it's that much smaller, it might slot in without too much fuss (though a fair bit of filler); otherwise, grind away the surface until it does fit inside the plastic part.

I don't know anything about resin casting/shrinkage, but if it is that it seems strange it's only shrunk in length. It's a perfect fit in profile and height. Perhaps they are just wrong......
