This caused my naza quad to crash upside down on the bed So i replaced with a new one unfortunatly the same brand and now my plateform dispite going through the set up prcedure is flying like its in manual in other words flies like a pig for some reason.

Sort of feeling more than a little pissed at present >:(

dizzy :(

Looks like you had tightened them too much for the alloy to take

i only tighten them enough to lock the prop from turning i cant do much more any less and the prop spins and i also use a 2 inch screwdriver shank half way through the hole to do it so i cant really dont think i can overtighten them tbh :(

dizzy  :(

Yea these adapters looks like the same as you get with http://www.getfpv.com/nx-4008-620kv-multi-rotor-motor.html (http://www.getfpv.com/nx-4008-620kv-multi-rotor-motor.html) these motors...hollow shat? wtf!?

Ive broken a few simply by tightening then down on the prop...  :-(

I switched to giantcods Grub Screw Type.

Just a matter of knowing what is enough Dizz, all chinese metal is rubbish and if differing strength, I have a DJI motor with a sheared shaft because of overtightening. they are all the same, top brand crap, cheap brand shit.
Chinese metal Shite!!!!!!!!!!!!!!!!1

maybe a little off topic - but .. T-Motor are Chinese?

How many re-branded stuff do we see on here anyway?  My original 3 year old naza 450 flamewheel motors are still going strong (maybe a new bearing needed as of late).

Is it a case of flavour of the month?  - motor sales drop, rebrand - new logo on the side?

Once bitten, twice shy in this hobby i think.

Cheap chinese? I think you will find they are all made in china along with most everything else we buy.
          Anyhoo if you use collet adaptors chuck the spinner away and use  nuts instead been doing that for years now never had any problems.

Sounds a good idea but in my case all the failures have been the threaded stud breaking away becouse the centre as been drilled too deep leaving just a fraction of the materiel left at the base of the thread  :(
The trouble is you dont know how deep the holes are until you take delivery  :(
I am going awy from these types of motor now which is a shame because these are very effiecient :)
My quad is nearly 3kg and hovers at 22amps
dizzy :)
