I'm not entirely sure this is appropriate for this forum but it's worth a shot...
I have propeller data ($C_T$ , $C_P$ , J , and $\eta$) and very very limited electric brushless motor data (motor diameter, shaft diameter, Kv, voltage range, max amperage) I am trying to put together a power available curve (P vs V) but I'm not exactly sure how to use the data I have to do so. How do I get shaft power from my engine data? Or what can I use?
