Also I came to these numbers basically by stealing configs from other mods and trial and error. I know almost nothing about doing curves properly in KSP so if someone with more knowledge/experience wants to look them over for me, I'd really appreciate it. Also I still need to fix the energy consumption--because thrust is so low on Duna, the energy consumption is also low. But in real life, the propeller would still be spinning very fast and using the same energy, just have lower thrust because of the thin atmosphere. I probably need to mess around with an atmosphere ISP curve but I don't feel like doing that right now
