Im running a 13 tooth pinion with a Align 25amp Controller and a TP-1900 Gen2 11.1v and im getting around 10 to 12 minutes flight time. The motor temp is around 110 to 148 after flights. One bad thing I see with theses motors is that if you have a hard landing the motor case and the top plate come apart best thing I would do is pull the top plate off before installing added some green loctite and be done with it. But other then that I have about 43 flight on my motor and shes still kicking. Below is a picture showing how the motor comes apart.
