Whats the deal with these motors?

I have been using these HK motors for about 3 months. I owned 2 of the original ones. These run 17a on a 9050 and 21a on a 10x4.7. No issues

So I buy 4 more. I notice the bell housing is machined a bit different otherwise they look the same. Put them on 3 new builds. 3rd build catches fire in air. Motor burned and esc melted to goo.

I test the remaining 3 motors. 25a on a 9x4.7 and 28-33a on a 10x4.7. @#$%&^$%%.... I'm assuming these are no longer 1200kv motors? This kind of stuff happen alot? Do I need to test each and every motor? Is the variance that much? Or is this something else? I have no way to test KV.

Does Turnigy use blind one armed monkeys to build these?

Thanks
