Hi, might I ask some questions about prop? I'm new on planes.

How you determine the thrust power from a prop?
Would it vary across between tests with different motor/engine setup?
Logically it will, then how we can have standardized the test data.
I think we can't expect linear scale value between 1000kv and 2000kv motor, because of difference in torque and other things.
Thank you.

Oops, I don't know if this is an article submission, I though it was a discussion thread.

I am using the 3 blade 25x12 PT prop on a 3W-110 with m-55 cans. The prop pulls well and is quiet, it is my IMAC setup and I score 10 on sound. The prop pulls well on the up line and slows the plane down on the down line.
