Disapointed

Few months ago I looked for a motor for my truggy after burning few cheap motors before. Most of the people here and on the track told me that the castle 2200kv is one of the best motor out there.
I bought it and all was great - temp and performance.

Yesterday at track the motor stoped working after no more then 3 month of usage. I ran it only on 4S geared for ~35mph.

I found that the shaft went out from rotor - see below picture.
The performance of the motor are great but as far durability I'm not sure its better then the novak or hobbywing that I had before.

Sometime I think that all the brushless electronics for 1/8 is still not mature enough, even that we spend a lot of $ for the best brands there are still too many failures.
