Here I`ve made a short video about how to control a SimonK ESC with an Arduino. (The SimonK firmware was already on the ESC when I bought it.) It can be controlled like a servo.
the code:

For my quadrocopter I have chosen the drive combination of A2212/13T 1000KV motors and 10×4,5 propellers. It`s time to get some data for the dimensioning. What I want to know is of course the thrust and the current at different rotational speeds. From that I can calculate how heavy the multicopter can or should be and how long I can fly with it. I screwed the motor with the propeller onto my homemade test-stand and connected it with a 3-cell Lithium Polymer battery, a 30A ESC and the Unitest 2, that I bought some years ago. Then I started with the measurement.

You can change the values and use it for your own measurements.
For my quadrocopter I needed some good and cheap motors. This A2212 1000KV brushless outrunner motors from ebay seller global.mart are very cheap and in this video you can see what I got for my money. I`m also measuring the radial runout.
