**1) When calculating the thrust of a motor with a prop, how do I determine the RPM of the motor with a prop (adding load to a prop)?**

2) Are there any calculations I can do to determine the ideal prop size without having to do any physical tests?

3) What is the most accurate dynamic thrust and static thrust equation I can use to calculate the thrust of my motor with a prop?

Motor specs:

kV = 1070; V = 11.1; unloaded RPM; 11877

Battery Specs:

3 Cell LiPo battery of 2200mAh of capacity.

If someone could help me out that would be awesome!
