Miles wrote:If you have the velocity constant (Kv), you also have the torque constant (Kt). They are reciprocals.
If you use Nm for torque and radians/sec for rotational velocity, then:
Kt = 1/Kv
To use rpm for rotational velocity:
Kt = 9.54929/Kv
So it doesn´t seem so interesting anymore. Maybe I´ll ask for the prices of the other two modells again.

It could have more power but handles very nice due to 25kg or so. However I am still interested in these motors hope someone is willing to test them
