In a 2wd ST I ran a Trinity 13.5 on 3s Lipo, but sensorless. The power of these motors simply is weak in comparison to other stuff I have run, including CC motors. But if you already have the motor laying around then it's not such a bad idea
SH Z-Car, Custom Crawler, 8s Savage, 12s XTM XLB 1/7 buggy, 4wd 4-link rear/IFS Pro4 truck, Custom Hyper 10 Short Course, Belt-Drive Mammoth ST 1/8 truggy, 4s 17.5 MM Pro HPI Blitz
Well there is this on-road carpet track near where I live. If I run stock class I'll have to buy a 17.5 motor. The esc will be the MM pro, and of course I am going to test it with my Hyperion G3 3300 mAh 6s pack, so there you go...
