hmm well i had this idea that that basically is what happens, the nacelle slides along the pylon. i understand what you guys are getting at but its how i always imagined the nova concept.
ill see if i can build the inner workings of the nacelle and see if what i have imagined would work (lol this isnt voyager so i need to check this lol)
cheers again for the positive comments and praise (put a smile back on my face)
