Hello,
Yesterday on my first try I broke both blades of the flipsky propeller for 6374. I don’t know why this happened…
However this morning I ordered a new set propeller+blades beacuse they sell the complete set only.
Do you know is there is a stl file for these blades or what can I do to repair them?
Thanks
They are pretty much identical to this one: Efoil 6384/63100 120kv-140kv folding prop by ThermikDreher - Thingiverse
From the damage on the leading edge, I would assume you hit something.
And considering you have the blades, I assume this happened on land?
No I was in the pool. I wanted to try the new toy. I didn’t hit something
Thanks for the link
You very clearly hit something with the prop…
Looking at the damage on the blades it is the trailing edge.
I think the only way he could have hit something was if it was running in reverse.
If I use some epoxy and carbon cloth do you think I could save them until the new ones will be delivered?
The rounded side is the leading edge.
The straight side is the trailing.
Or I have been running them backwards 
Round is the LE. Must have smacked something really hard!
My mistake. I do not have that prop, but thought the rounded site was the trailing edge.
In that case you did hit something
A few years ago I repaired broken blades by completely laminating them with carbon in one layer. But since yours broke in the most loaded place, I think repair is pointless. I can only advise, based on my experience, to treat plastic blades as consumables - this is an eternal story. By the way, if you want to know what you hit, ask your dog to open its mouth. And if it has no front teeth - the answer is obvious. But seriously, inspect the board, perhaps the cable mount has fallen off, because, as was correctly noted above, it was a hit.
Although I thought that perhaps the blades broke when opening, and the broken fragments on the blades are secondary damage, caused, say, by the flying blades hitting the mast or each other.
Pretty sure those are the aluminum blades.
Can not imagine they have enough inertia for that to be secondary damage.
Yes, you are right. First I looked at it on my phone, now on my computer, and the fracture structure is typical for metal. I was misled by the topic starter’s request for an STL file, and I decided that the blades were printed
