Dustflyer,

I have already stated in my thread that the importers have no more of these returned per amount sold than the more expensive ones so RELIABILITY IS NOT THE ISSUE although I do agree with what you say about the bearings but im sure if this one is not ballraced there is a ballraced version available for a few dollars more.
I do think that sometimes us jet modelers think that we must use the most expensive of everything regardless, maybe it come from the time when we had to because everything less than expensive was not up to standard. Like servos for instance, only a few years ago to get 5kg torque you needed to spend a fair bit of money but now you can get one with good relability for only a few dollars.
