Thanks; Do we have to remove the circlip under the prop to do so? Or just pull super hard? I have a 6384 by flipsky
It should pull off, then when returning hold it firmly so it doesn’t slam on, it does happen but I have never had issues.
Rinse, dry then spray with CRC lanolin or equivalent. Some people keep the rotor, the part that comes off, seperate all the time so it is dry, but most don’t.
There are pictures of people who don’t do anything and the motor can seize together, especially from salt water and force to separate will often break the bearings.

Before pulling hard, you need to remove the circlip. Should be ok to leave it without circlip, if you run it with a folding prop. With a normal prop people lost the bell and prop.

It worked! Thanks again. I think I ll go with mark’s suggested method to let everything sit in mineral oil for a few days.
Hope it’s ok to post this here. Mechanical comparison between aliexpress 65$ bduav 6384 120kv and 6384 130kv Saite from alibaba (directly from Saite). The Saite costs around 140$ plus shipping. Incl tax around tripple the price of the cheap bduav.
Saite comes with 12awg wires which should be ok to use as is. I also got the Saite with the shaft already cut flush at the end of the bell. Rotor magnets seem to be coated although I did not ask for a waterproof version. Stator is not coated with epoxy.
Bduav needs new cables, they are too thin (awg 16).

The BDUAV motor has the same stator length as the Saite 6374 version.

Just tried the Flipsky 6374 vs 6384 again, back to back in clean but small foil assist sessions.
For me 86kg and 900cm² foil there is no upside using the 6384. The 6374 runs super smooth and far more power than needed for me.
The 6384 feels exactly the same, just with extra weight.
In addition my 2 6374’s look almost like new after about 50 sessions, while the 6384 had its bearings fail and ok, but visible amount of wear on the stator.
I personally think the 6374 is just better balanced and the shorter distance reduces load on the bearings.
So unless you really really need the extra power, I would go for the 6374 for sure.
