So, after I had my first DJI motor bearring starting to make the dreaded bearing noise, and I found it hard to change bearings, I thought, lets upgrade to T-motors, they are supposed to be better, provide better thrust etc. Now, reading some reports it is questionable if they are really that better in providing extra flight time etc, anyways. So, got my set of 4 T-motors and flying I went. After a few flights one of the motors got a little tick sound. Not the typical bearing sound. I thought there must be something in it, or so. Opened it up, but never was able to put it back together again. So, must be coincidence, lets buy another set of 4. Changed the motor, but after just another few flights, the dreaded bearing sound. Ah, still have a ccw motor left, lets change... Guess what. A few flights later the motor I changed; the dreaded bearing sound. No more ccw's left. (i hope a friend here will be able to changes shafts with one of the 2 cw's I still have left) Is it normal to have so much motor trouble? (yes, I used prop guards a few times, and no i did not mix up screws) I will not buy another set of T-motors, with the rate I am consuming motors, it's cheaper to use the DJI's, and maybe I once develop enough bearing change skills.
