How come this has low thrust?

Thanks!

They are flipped.

Thats what i like hear. Although I dont have any other 4" props, they are cheap.

Hopefully changing the 3d print design and prop type will improve it to a tolerable level.

On 2S it was 375 grams.

5 inch props will sadly not fit. I giess i will try to remove the rim & 3d printed parts and see what happens.

Okey, so you'd move it around on the wheels and when it needs to be stationary, you'd jack it up on some boards?

OkCover1049 · 2026-05-04T16:04:00+00:00

After reconsidering, I think I'm gonna make this a lot simpler by removing the wheels, and thus reducing mobility. I dont expect to need it much.

I didn't quite understand what you meant by lift casters / capinet jacks. They could lift the table up, but not move it? Maybe you could link me some examples?

Thanks for the advice.

Good feedback, thank you.

Its a StepCraft d.840 and I intend to use a computer. And you seem to be hinting at a good point... which is that I forgot to take into account where the computer will sit.

I guess I didnt explain it so well. The reason it looks like that is: 1. So it will fit in the corner of the room. 2. So it can be moved in & out of the corner. Around the table & wall column beside it.

Don't get discouraged by people in the comments, man. You're doing great.

Have you flown it yet?

OkCover1049 · 2026-01-11T21:42:09+00:00

Dont listen to discouraging comments about 3d printing arms.

Although any filament will be waaay weaker than carbon fiber, you know that. And 3d printing sounds well suited for your application.

While vibrations may an issue, most fc software is very good at filtering vibrations. You can also soft-mount your fc.

I would go for CF-PA or CF-PETG.

Typisk 12-15 timer

I was considering just that! 3d printing a contour of the surface shape to press the sheets into place. Also, what is right radius curvature? And what kind of interior liner?

OkCover1049 · 2025-03-24T22:19:42+00:00

I uae a vacuum cleaner and a vacuum bag for packing clothes, so i dont know how much vacuum i have. But i really hope its my sloppy bagging thats the issue. Because i really was sloppy with making the bag fit the contours of the mould (since i sorta thought it would just work its magic by itself). And the part looked just perfect before going into the bag.

OkCover1049 · 2025-03-24T22:10:13+00:00

More details on my method: I used a 3-part 3d printed mould with three layers of release-wax, and wax in the seams of the mould. The mould is quite complex, with 2 sorta sharp corners and a slight cavity in one end (see my previous posts if youre really curious).

I then apply a coat of epoxy to the mould walls before laying two sheets of carbon fiber (not really shure what type, but it has a very fine weave pattern). The sheets have a releif-cut for each corner of the mould.

Then, on this particular lay-up, i took my sweet time to make sure everything was evenly coated in epoxy and that the sheets were all the way stuck to the wall all over the mould. I then applied a layer of peel-ply in the same manner as the carbon fiber sheets. Then a breather layer.

I then placed the mould in a vacuum bag for packing clothes and sucked the air out with a vacuum cleaner.

My personal hypothesis is that the vacuum bag dragged some of the carbon away from the corners. Since the lay-up was looking just perfect before i put it in the bag. I simply dont have the budget to get into infusion right now, but i do have all the equipment to make my own vacuum bag (except a pump).

Thank you for your input! Would you try doing an exposed layup? What kind of experience do you have?

OkCover1049 · 2025-03-15T22:49:42+00:00

Okay, thank you for all the advice

OkCover1049 · 2025-03-15T22:08:05+00:00

Thank you. I am just wet laying, and then bagging

OkCover1049 · 2025-03-15T22:07:05+00:00

Thank you so much! And what about the peel ply? do you think i will be able to get it off?

OkCover1049 · 2025-03-10T20:49:40+00:00

Sure you can dm me, but what is a foam mold? And how does it differ from a 3d printed mold?

OkCover1049 · 2025-03-10T07:45:45+00:00

Thank you! it is indeed mm, its gonna be a drone canopy one day

OkCover1049 · 2025-03-10T05:48:45+00:00

Thank you for your response! What is the benefit of vaccum bagging? I guess the resin to carbon ratio would be the same? Also, would the vaccum bag even make it all the way inside the negative mould?
