I bought this motor in January 2013 for my SC10 4x4. It has a lot of power and a lot of torque compared to the Reedy 550-SL 3500kV and 4000kV. Motors runs great on 2S and 3S with the stock gearing, on 2S it's temps at 160-170F after 10-15 minutes depending on ambient temperature (65-75F). I own a lot of LRP motors and ESC's and all of them have performed perfectly. The X12L has been in my 4x4 for more than a year now without a single problem. It ran great on the sensorless SC1200 RtR ESC and runs just as good on the sensored RX8 Gen2. It's great upgrade in the SC10 4x4 if you're looking for more power and speed than you get from the stock 3500kV RtR motor or the Reedy 4000kV 550-SL. Judging by Spangler's comments in his review (slow, no punch, 187 after just 5 minute), he obviously had his gear mesh too tight or something else was wrong with his truck causing a lot of drag on the motor. The X12L is a powerful 550 and runs great in the SC10 4x4, but it can't fix user errors.
