One thing you can do with this also is replace the 6 outward stubs with a
technic liftarm--either the 1x3 one (part 6632), or the 1x4 one (part 2825).
This has a few consequences. One, it makes the structure slightly more
compact vertically (assuming that this is axis of the prop is vertical).

conducive to propeller blades. Instead of having axles radiating outward,
you have liftarms, to which it is easy to attach plates.
I found that it also allows for additional structural support, if you choose
to add it. I took a few pictures with my digital camera of a prop that I
put together. You can kind of see the extra support I added (the black
pieces) in the last two pictures. Sorry about the use of black, which
doesn't photograph well, but I didn't have anything else handy. The
pictures can be found here:
