I found the referenced thread really interesting, and wanted to see if anyone wanted to comment on the Roton rocket (if you're not familiar, it was a rocket design that used a helicopter rotor to get the vehicle above the densest part of the atmosphere, and also at re-entry to land as a helicopter). This vehicle is always drawn with four blades. I was wondering if this seems an optimal trade-off between maximum thrust (which is what you're after in this application) and power required (minimizing power saves you fuel, scarce in a rocket)
PS.: I included a link to an article about the Roton, for those who want to read it.
