They usually don't "fail", they just lock up. It's not an issue unless your clutch won't release and the engine dies. Quick UK now make a AWSOME replacement hub, but I have over 400 flights on the new TT hub (same hub as in your kit PV0409) with no problems.

Keep your stock hub lubed with ATF and DO NOT over tighten the lower Jesus bolt. Only tighten the bolt so that the nut and bolt head just start to contact the gear. I keep mine so loose that I feel I need to add Loctite to the nylock just for comfort.

Over tighten the lower J bolt tends to deform or egg the auto collar on the main shaft, just a little, but enough to help it lock or bind up. Also, I don't remember if the SE comes with the reinforcing ring, if it doesn't, ADD IT and have it tightened by a gorilla! You shouldn't have too many troubles, unless you got one of the one-ways that just refuses to play nice. Add a few drops of ATF to the top of the auto hub about every 20 flights or so.

Don't come off the throttle untill you see your GOD!

Normally you won't notice much. The autos will have a little less marginal but should be managable.
Try and see, not everyone have problems with it.

I've noticed the engine will not come down to an idle until the headspeed is almost bled off at the bottom of an auto. The head continues to spin the engine over even though the throttle is down to an idle (As in throttle hold).

I also notice the heli just doesn't seem to run as good, the auto hub not only helps on autos, but also allows the head to free-wheel during certain helicopter flight situations.

Try your stock one, if it locks up buy one from Quick UK.

You fly RC helicopters? Can I have a ride?

I had both stock one and QUK locked and I auto the heli with no problem. Actually both times I was hitting the throttle hold at such altitude that I didn't even understand that the hub was locked.

What Blake says is correct even if I think that if you tight the reinforcing ring a lot it will again deform the hub. I think the manual mentions that also.

he had a isolated incident with his QUK hub, not to be confused with all QUK hubs lock up...cause they dont... scince the release of the QUK hub I've only heard of three locking up...not to bad considering and all three hubs were replaced gratis (as well they should be)

Ask your Doctor if getting off your ass is right for you.

A tip from www . Team - raptor . net regarding the TT auto hub:
Next time you have it out. take the inside sleeve that is inside the needle bearings.... turn down the outside diamiter a few 1000's with some fine sandpaper (while its spinning in a drill or lathe) this will allow more oil to flow between the needles and keep it lubed there better. Several guys were testing this method since mid summer and all had success.

Dont take too much off.... or it might break free and slip.
