also not a friend of super glue anywhere near the prop or the thread. Use http://www.nutmanufacturers.com/lock-nut.html a nyloc lock nut and you are on the safer side. Just take care the motors mounts are out of alu soft and the nyloc nuts most of the time out of steal. If they dont fit perfectly you can damage the alu thread from your mounts at the moment were you start tightening the props. ! If your issue is that the props can still be moved on the mount although you already tighten the nut as much as you can. Think about applying a washer under the prop above the motors mount, the ones with profile little bumps dont know what you call them. I am doing this now since a month or longer, since on the QC Tory tiger motors etc. Who started to paint the mounts compared to the axi mounts, there is less friction for some reason and the prop no matter how tight can be moved with some force.

I find that even the best prop adaptors are made of cheese! anyone to links of titanium ones please post!..Don't use Nylocs.. I dont use anything just check before every flight and DONT over tighten.. if you want to try and eliminate the risk of the nut spinning off use a star washer on an aluminium nut it will go no where!

Dave where do you get your prop adaptors and what flavours do they come in
sorry just couldnt resist it

I supose they will be ok but its what you are running them down.. if the alu on the shaft is cheese you need to be really careful.. I keep at least two spares of prop adaptor per motor type..
Again I use nowt but just a good owd engineers feel

just my 2cents worth of info
alu nylock nuts on an alu bolt or alu prop adaptor i personaly wouldnt recomend
alu bolts etc are a pretty soft metal for threads and the screw threads tend to get messed up fairly easy if not careful
adding alu nut to alu threaded shaft doubles the chance of messing up the thread if care is not taken
add in the nylock and it gets worse
alu threads need to be kept clean and clear of debris as this is a softish metal
you prob better off as others have said to use some sort of locking washer
when running a nut down an alu thread it should run nice and free if any resistance is felt back off the nut as there is probably some debris on the thread etc
with a nylock nut you would not be able to do this as to the resistance of the nylon in the nut itself thus extra chance of damaging the thread before you realize it
need to take that bit extra care with alu screw threads

Alu prop adaptors are made of cheese then.
So lock washers it is, just have to make sure I don't drop them in the middle of a field.
How about second nut as a lock nut ?
This question has been of interest with respect to our new Y6 as the lower props will lose their nuts due to vibration and fall off far easier than the top ones.

locking two nuts is an idea
the only thing with that is as you tighten them to each other this will try to stretch the alu thread between the nuts if over tightened thus destroying the thread also
sooner or later you are gonna strip a thread as most of us do somewhere down the line
just be careful and try not to overtighten nuts on alu threads

What kind of lock washers are people using? Last night I tried some props that really short hubs, and I'm using a nylon washer to make up the distance to the nut. I'm afraid it's going to slip though - do you recommend using a star washer in between the nylon washer and prop?
As for the original question:
I know Tabb uses nyloc nuts.
I personally think loctite is really annoying. It gets in the threads, and then once you take the nut off, it can be hard to put the nut back on. I had to soak them in acetone to get them clear - not very conducive to changing a prop at the park. Plus, as others have said, loctite probably damages props.

the lock washer i am using on a QC same as torx KW tiger motors etc.
In my case i have 11 grams CF 12 3.8 that cant even be screwed on with one washer from the top since the thread is to short, so i use two. Even using one upside down of the prop washers otherwise it wouldn't fit on the props.
Works for me without any probs. None of this should keep you back from checking the screws after one or two flights just to go sure. No matter if nyloc of the super glue you got etc.

Alum threads on alum nuts will eventually seize on you. It's an engineering No No. If it picks-up its welded together. Hard anodised maybe!

In this example from the F1-535, the prop. (made from carbon infusion nano tube technology) has the mounting holes drilled directly in the hub. Seen along side an APC you will note the added torsional rigidity built into the hub section. APC's bend!!! This method saves weight by removing the adapter altogether. Carbon Nano tube is the strongest substrate known to man.
