Anyway a bit more detail before I start modelling. Note the front view of the secondary hull and nacelles: they are not cylibders in the usual sense, but a bit more ovoid, or rather spherical on the sides and a bit flattened on top and bottom. Note, too, how the support pylons will attach to the nacelles---as seen from front (or back) they will have some suggestion of something wing like. Something like the gull wing of an Vought F4U Corsair but inverted.
Hmm. I think I might widen the nacelles a wee bit more.
