Clutch issues, Tail hub breaking, Tail tightened too much at factory, Swash play

I'm very interested in going back to nitro for next year.
The NX4 got my interest over all over nitro.
What are the real facts on these issues ?
Please avoid the "mine has been running perfectly" etc ..., not that I'm not interested by your experience, just that seeing the number of issues on this model on these particular points on different forums in North America and Europe ...
Those who had problem(s), what was the core cause and how can we fix it to make the machine more reliable in time ?
BTW my X4 II has develop in less than 10 flight a lot of play, is it common to Gaui quality ? Never seen this even on other machines and I've seen some in 15 years .... and far away to be impressed except for the smoothness of the machine ....

Thanks for your constructive inputs, lets make a list of core cause / fix to help all NX4 users / future users

Thanks
