Dunno how we gotshifted from motor power to jello and vibes lol. I started out talking about how to tell how powerful a motor was for a multirotor. I believe right now that
the motors I use put out something like 30 to 35 ozs of thrust at 210W.
The 210w is the max rated power ( watts ) for the motor ( if they didn't exaggerate, which is common ) BUT each configuration ( batteries, esc, props/blades ) differ so not all of them will reach that max amount... This means that the only way to know is to run a static test using a watts/amp meter ( like a Watts-Up or similar ).
In short, published numbers are for reference only. What is posted by many of the cheaper ones are exaggerated... so only trust the numbers you have tested. Different batteries, esc, props/blades will also affect the final test number, so just another reason to test it for yourself.
