    While it's been debated on whether or not it's safe to use on the prop nuts.. (I say it's safe so long as it's carefully applied)

    ...what about the rest of the Phantom?

    in the coming week or so, I'll be dismantling and reassembling my Phantom parts into a new shell. (bad crash dented my original)

    The screws that come with the Phantom that are used to attach the landing gear do appear to come with a form of blue loctite/threadlock already applied.. so one has to assume it's safe to use elsewhere?
    or is that another kind of threadlock that's been applied? if not, what might that be? last thing I wanna do is lose one of those little screws!

    No don't use Threadlock, throw those useless Dome nuts out the door. These are lighter, and lock into place, your blades will never come off

    I will never go back to using those useless dome nuts, the Phantom is the only Drone I have with the nuts coming off, and all use a same sort of dome nuts.

    The Phantom ones are horrible and you should not have to use Threadlock if they where decent from the start.

    Get the above and no worries about nuts coming off in mid air.

    It looked like blue Loctite to me but is probably a Chinese copy of the actual Loctite product. Obviously you only want to use it in metal-to-metal applications and I'm guessing that all the screws in the Phantom body go into threaded metal inserts. I don't know of any threadlocking compounds that are compatible with thermoplastic like that used to make the Phantom.

    Loctite 242. There is a guy in N Ireland sells on eBay at a reasonable price.

    All of the Loctite threadlockers I've looked at recommend that it NOT be used on plastic parts.

    "Not Recommended For ... Use on plastic parts, particularly thermoplastic materials where stress cracking of the plastic could result"

    Yes and this has been stated many times here already and was acknowledged by the original poster.

    The discussion is about the blue threadlocking compound that is being used, from the factory, on the metal screws for the landing skids that go into metal inserts.

    No one is suggesting that Loctite be used on screws going into plastic.

    The nylock nuts are 6mm per your link to a UK site. I want to get them at a local store in the US. You don't,happen to know the thread cut on the screws do you?

    Just look for 6m ones at your hardware store, should be easy to find.

    You're looking for M6x1 and you probably want the low profile ones that may be harder to find in a local hardware store unless they specialize in fasteners.

    This is a link to a standard height nut you can get at Lowes:

    May be too tall for the nylon portion to engage fully. Somebody would have to measure the amount of shaft sticking up from a seated prop.

    These might be better.

    Exactly,. last thing I wanted to do was create yet another thread for denodan to preach about using M6 nylon nuts ;) :mrgreen:

    I think it could be the Plasti Dip, just lightly dip the thread in it, let dry and you're done.
