I have a 6S senton BLX 2050 KV motor. I have a couple of questions one is it better to just replace the motor if it's bad or should I try to open it up and clean it. The motor is extra loud and it seems as though the drive shaft has a lot of play in it. Several times the driveshaft has moved causing the pinion gear to grind up the red motor mount. If I do replace the motor is there any brands or Motors that you recommend or should I just replace it with an identical type motor. I'm happy with the amount of speed I get with this motor but I'm more interested in reliability and durability. my ESC and everything else is stock. What replacement motor can be installed with least amount of modifications as well as the best bang for your buck. Thanks for any input, this forum and all its members have been so helpful in the past.
