Here is that part broken down for you. It's all cylinder primitives combined with a bit of tweaking...
The prop flows into the sides but I prefer the look of the tighter edge where the top cone comes in.
I know hard surface modeling, I was a professional surface modeler and Maya is a pain in the ass to make clean hard surfaces! Especially negative space like holes and notches. The geometry gets out of control very fast and the modeling tool set is very limited, in particular, poor axis control, and very finicky, limited, and in some cases just plain missing extrusion , beveling, chamfering, and thickening tools, and very poor accuracy. Fine for artists I guess.
I still prefer the challenge of hard surface modeling to subdividing to 80 gazillion polygons and sculpting.
