Hi @Bzhwindtalker ,
Any chance you can share some more details on the prop?
I did try a few ones in carbon but the efficiency was lower than the nice aluminium ones. What were your thoughts on your carbon ones?

Saite will make custom motors for anyone, but you need to submit a design and it will cost a few thousand to get a prototype similar to FD HP with rhe plug etc. Theres an obvious reason for it. Its also good that they honour their commercial agreements.
For a normal saite waterproof its around $120 or so. They will happily give you a generic with a long cable.

My carbon blades only lasted two sessions last year due to the hub failing in cold water. Then I went alu print and those have been great.
I did not have motivation to go forged blades again since then, but a fellow DIYer shared the STL for a replica FD blade, and I also found a hub for FD blades by another user. Based on a fd style blade, my friend designed a 3 piece mold that I will try soon.
I had made two blades based on FD scan as a test in a resin mold I made, but they were not compressed and precise enough to go much further.
Hub is PPA-CF

Which XT90 are you using?
Xt90S, I had too much sparking on waterproof xt90.
I had some grease in the connector during potting and I think I may have a channel of grease instead of epoxy to the top of battery.
That or my sealing concept is not working as I would like, maybe the alu part has too much granularity on the surface.
Also received the new vesc express and maytech rx today, after a bit of open heart surgery the system is back to fully featured state.
I like that status led are visible thru the gel and cover, but ideally those would also be visible with the foil mounted for quick troubleshoot in situ.

Forged blades here we go again :
Weight after initial sanding 9.6, 10.1, 10.4 gr
Some surface imperfections, and the fiber did not fully form around the screw hole, making a weak point in the part at the worst place.
I think that is more a problem of process than mold. I should have taken even more care into pushing the fibers around the 4mm rod during fiber loading.
Leave the rod out and 3D print a drill jig. That way you will get a perfect section to drill.

If this hub is the same as the one in the photo, I downloaded it too and found it to be quite odd, with lots of artifacts within the model. So I completely rebuilt it. It’s not perfect, but it works. The PPA-CF blades also work on 12S.
I made it! I’m not a professional though. I uploaded a v2, where I basically removed the negative step to the blades.
Yours looks way cleaner 
I also don’t consider myself a professional and have only the most basic skills.
I printed V2 and will test assemble with the blades
The blade root was a little wide, had to sand them down on each side. The blades do to fully fold, is it also the case on your tests?

I haven’t had the time to do it yet. I also have this problem with my Alu blades, when I tighten the screws too much. The ones for the blades and the ones that connect the hub to the motor
Will test that during tomorrow lunch break, fresh 6384 120kv and cf fd style prop.
It is 90 gr more than the 6374 maytech setup
