Google doesn't find it anymore, and I don't have it in my browser history, having changed browsers recently.

This is on a Hungarian website godolloairport.hu that excuses for undergoing maintenance but promises to be back soon.

Yeah, I already tried it today, but it's giving vastly different results to the other one, so no way to compare apples to apples. Also, no idea what "Tk" and "Pk" are, and they seem to have a huge impact on the result of the calculation.

Tk is a thrust constant and Pk is a power constant. As the page doesn't give the formula it uses I can't say if these compare to any others directly. These constants fluctuate within the same series of propellers substantially and that just doesn't make sense. I've always used the formula published in the Astroflight Electric Motor Handbook which can be found at http://astrobobb.com/
