Why isn't this posted on the PL bboard, where there are lots of people who built the kit? What's computer-assisted about this question?
The nacelles do snap on, but there's a trick to it. You have to stick the tab in the slot as close to its proper angle as humanly possible. The tab has GOT to go under the pin inside the nacelle. It can be done, but it's tricky. I've gotten the hang of it, and have managed to do it with no problem on a half-dozen builds.
The other way to do it is to put the inner half of the nacelles on the pylon first, then snap the outer half on while making sure the nacelle pin goes over the pylon tab.
