AB=5.6 mohms at solder tab 7 mohms at bullet
BC=5.6 mohms at solder tab 7 mohms at bullet
AC=4.4 mohms at solder tab 5.8 mohms at bullet
Just to compare here is the results for my old hpi alphastar 2350kv made by castle with shortened wires (old design without solder tabs)
AB=6.2 mohms at bullet
BC=6.2 mohms at bullet
AC=6.2 mohms at bullet
Perfectly equal phase to phase. I have to say that I am a bit desapointed by the result of the 1515 sensored. I will have to check how the coper wires are connected to the tabs, maybe a defect. How can I check if it's a genuine castle ? Amain is a reputable store, isn't it ?

Disappointed by what?
Those are excellent numbers. At 100A, the whole motor is only dissipating 50W.
The difference is simply that there are tabs -- and A & C phase have slightly higher resistance because they go farther around the rear of the motor, while the B phase terminates right at the terminal.
Perfectly normal. The motor phases are balanced, there's just some additional resistance on A&C for the tabs.
Thanks!
