Bendik,

Here's some performance data and graphs for an AGNI 143 attached. Also here's a 95 R which is a higher RPM/Volt. The R stands for reinforced.

AGNI as you probably now know are now Saietta. No load torque per amp and rpm per volt is based on:

 Kt (N-m/amp) = 9.5478 / Kv so if you know one value you can calculate the other for a DC brushed motor of this type.

I just asked Cedric about the Kt, Kv values for his newer 119R motor.
