I suppose that the silicone accounts for a significant portion of that 4.6kg.
Could you use PU?

Your assumption is absolutely wrong. The main mass consists of 21700 cells. The weight of the original FD Max with a large battery, by the way, is 4.5 kg.

Looks good. Do you have photos of the top? Is it 3d printed and is it strong enough to bolt the mast through the unit?

52

Regarding the second question, I have already answered it.

Unfortunately, I can’t post the model yet, but here are a couple of photos to help you understand the concept.

Thanks, Interested to know how you make sure that the battery does not fold down due to water force. I see the 4 holes th the board travel axis, they have some tubes or sliding function for the battery? I ordered the same latch you used, cheap on amazon.

I don’t quite understand why the battery should fold. The cells are housed in a housing.

And yes, the battery is also filled with silicone.

How you injected the silicone?

59

I use 50 and 100 milliliter syringes.

60

And you create entry hole and a few exit holes (to make sure it filled the volume) in the enclosure?

61

Which cells did you go for? Molicel P42a? P45b?

Thanks

62

Yes (Post must be… must be…)

Eleventh session on the printed foil starter - everything works great. The carbon mast was not rigid enough. Replaced it with an aluminum one, it became better but still not ideal - there is some play, heavy weight. Ordered the HM mast, but they say that it also does not have enough rigidity, and UHM is incredibly expensive (

@rttn commericial plans or will the CAD files be shared with community? (Perhaps over DMs to skip our friend at Maytec…:sweat_smile:)

I am ready to share files, but personally. Contact me via private messages. There is one condition - personal non-commercial use. And also, I don’t have much free time now, the possibilities for consulting on the project are limited, please treat it with understanding.
