Tested TS1900 and 2400 motor with HW Xerun 150A ESC on different timings on 4S and 1900 also on 6S. They are delta would, so adding timing is little bit tricky.
I tested about 20 other motors... so apples to apples.
TS1900 compared to Tekin 1900 4030 and Viper VF8 1.9 :
TS1900 is also the same as Hacker 1900 V1:
TS2400 is actually more of 2675 and thus hotter than 2650 Tekin (also Delta):
TS1900 on 4S ... run 0° timing
TS2400 on 4S ... run 15° timing
TS1900 on 6S (yes!) ... run 11.25° timing
