ivanwhlee, Well it looks like someone tried to remove that bearing with a sledge hammer! Listen, we all make mistakes. Unfortunately, sometimes "price" gets in the way of when
trying to make an informed decision. A couple of years ago I bought a Dualsky outrunner motor thinking it was capable of "doing the job". It failed after 106 flights! Now, you would have thought that I would have learned but NO, after going back to my Axi 5330 FAI motor for a few months, again I was tempted by the cheap Turnigy motor thinking it
could "get the job done". I've learned my lesson, NO MORE JUNK! This is why I was not surprised with your findings. tianci, to answer your question above, my statement related
to the Turnigy motor was about one or two of the electric pattern gurus here in the U.S. jumping on me in the original Turnigy SK motor thread earlier this year. My statement did
not pertain to you. My Neu F3a motor will be here in the next 2 weeks! I wish you both continued success & if I can help in the future, please let me know. Regards___TNWalker
