how do i do i measure or determine loading... or since i know my
torque will be good at any speed should i design the propeller for
maximum power which i know is going to be ~3400rpm.

and how do i factor number of blades in the the equation...simpler
would be better but wont more blades allow more thrust per rpm and
smaller diameter and lower tip speed/noise...part of the reason im
going electric is to make it as quiet as possible...

thanks!!!!

More importantly, how do you factor in the couple hundred pounds of battery
weight?

Start by doing some power required, and wattage required calculations. Then
convert that to battery weight you can afford. You may soon see why
electric flight has not become a realistic option.
