I'm looking for an equation (or set of equations) that would allow me to predict (with fair accuracy) how heavy a payload a quadcopter is capable of lifting.
I assume the main variables would be the ...

I am using an Arduino Uno to control an ESC for my (in progress) quadrocopter. I am currently using the servo library to control the ESC, which works great.
Except..
A count of 100 is max speed, ...
