Is there anyway to identify a TP motors KV?
its 92mm long

so I did a bench test to see if I could get a real time rpm measurement
with the prop and flex shaft disconnected from the motor I am only getting 17900 rpm on 5S that seems really low unless this motor is a 1050kv its suppose to be a 1650kv
did I do the math rite?
It should be written on the can at the wire end. That's how mine are.
1050Kv on 5s should be 19,425 rpm.
I get closer to 18,200 for the 1050 but then that would be loaded with good packs. Most of my TP’s do have a KV on them but it is just a small sticker. Perhaps one of those little Watt meters would help
The kV is written in pen on a sticker near the end bell and is pretty useless after about a season. I take the stickers off. Which reminds me, I want to start engraving that kV number into the end cap on mine.

Here is the setup that I use to check the actual Kv.

I am very interested.
I ask, disarming the motor to determine if it is a motor with configuration Y (star) or with configuration D (delta). And then you get the internal resistance between two stator terminals. (using the method of circulating a current through the winding under test) R = V / A. Obtain the internal resistance in that way and then compare that value with the manufacturer's RI tables. Can it be viable?
I think I understand. Excuse my English.
I am a beginner in these subjects. And for what I am reading:
I think you should not worry about the type of configuration D or Y to choose an engine to the same KV. Both are very effecient. But you should know what kind of time or progress to use in each type of configuration.
Yes.
I choose the kv that I consider appropriate.
I only take precautions when choosing the timing or progress.
I have 7D engines where I use 0 timing. And other 1.5Y engines where I use 11.25 timing.
Perhaps the most advanced runners can notice some difference between the Y and the D engines at the same KV number.
