I just installed a 50-65 340 on my airplane. I am running an Electrifly 60a ESC. On the first run up with a 14x12 prop, the motor made a bad screeching sound about half throttle. I tried changing motor timing to 20 degrees, no difference. Well, it turns out that the noise was caused by a bad vibration in the outrunner housing. I could actually see the housing vibrate.
I noticed that the outer housing wasn't pressed onto the motor shaft far enough, and the shaft was able to move a full 1/16" back and forth. I adjusted the gap and tried it again. The vibration happend at a higher throttle point that time, but the magnets came off of the outer housing.
I will never buy another Turnigy product, I guess that's my fault for going bargain basement. It would cost me too much to ship back, so I'm going to put that money towards a better motor.
Live and learn, DON'T buy Turnigy!!

All my planes are powerd by Turnigy with not one issue.
Now, my motors are mush smaller size up to about 36 mm.
From most posts it seems that small to medium size motors are good, but you do find similar compaints about the larger size models.
 
So not ALL Turnigy are garbage, just happen to be the one you need.

It seems that there was a bad series in production. I bought several 4260 Turnigy motors and if you open them, some of them had the magnets fixed with a metal ring on the rim and on the others the magnets are glued into position with a green glue. The metal ring solution didn't work very good, one or two hard landings and the ring became loose and the magnets scratched.  I had to fix them. One motor did that thing again, the other one is working until today. All other turnigys work very fine.

Sorry for your bad experience but dont let that deter you away from turnigy, they do make very good motors and Ive never had any problems from the 14 engines Ive bought.

Anytime I buy a motor for any model, and for any application, I always first take it apart and examen it. 

If things(magnets, retention rings, bearings etc) need to be glued better, and windings need to be secured better, I do that.  Then I re-assemble, and I drill a tiny dimple into the shaft where I desire my set screws to sit, rather than just using a flat spot. I re-assemble with a thin film of loctite green on all connection points that I wish to stay connected.
 
This whole task takes about an hour to do, and it's easy work. 
 
I have never had a motor problem using Turnigy motors, even pushing them to 2-3x the rated power. 
 
The hour I spend going through the motor gives me piece of mind, and I get to rest assured that I can trust the motor.  I recomend it.

Sorry to hear of your loss, but what would you have done if it was a fuel powered model?  They are notorious for the motor dying and requiring a 'dead stick' landing.

Part of any training should be to kill the motor and then land the plane safely.  Just because a motor dies it should not be the end of a model.
Cheers, Dave.

Liveforphysics has great advice for any brand motor purchased from anywhere. Even the most expensive motors have faults from time to time.
Dave has good advice as well. It pays to shut the motors down and practice dead stick landings. Plus, you get a much better idea of how your plane glides and flies during those emergencies.
Best Regards

I have to say people, please be realistic.  I have owned AXI motors and seen a dozen other top brand motors die. Motors that have burnt out due to QA problems in manuacture of the windings.  SH1T happens people.  I use several Turnigy SK series from 28mm to 55mm and still drive a couple of AXI 2826 and have had no further problems with either brand. Turnigy seems to be excellent value for money against the more expensive brands. Quality can not be determined by price. Extended warranty is just a good marketing tool for expensive brands becuase you dont get anything nowadays for nothing. happy days
