Hi Chris!
I have an engineering type question. I'm still not understanding the relationship between Kv, volts, rpm and thrust.

I get Kv being rpm per volt.

For my question, let's use Eflite 90/325's. Assuming correctly sized props, which will give more power/thrust:
8s with a smaller prop/higher rpm or 6s and a larger prop/lower rpm? Or am I still completely off the trail?

Thanks in advance!
