Hello everyone.
My name is Markus and I am 43 years old.
I live in the south of Germany, BlackForrest.
I’ve been kitesurfing since 2004.
This year I’m also traveling with a kite foil board.
First of all, many thanks to the great contributions here in the forum.
But now to my first build.
Everything should go to my Slingshot Alien Air Kitefoilboard.
Your Stator might die due to overheating. Potting it completely is not good concerning heat dissipation.
Just some brushing the EP over the metal parts to prevent them from corrosion is enough for the outrunner motors
Just a note: Justin at endless sphere did some tests with thermal epoxy potting, there was actually a small benefit when the best thermal stuff was used.
Anyway, you’re right, we don’t really need it since the cooling is excellent on set outrunners also without it and worse when potted with normal compounds.
First of all, I am glad you put all detailed here including many pictures.
As your hobby 3d printing, I will ask you some questions :
Is it practical to 3d print the box - the enclosure for all the electronics? I saw methods for waterproofing 3d printed stuff…
The motor pod - do you intend to waterproof it? Like maybe it will collect water and becomes havier… BTW have you seen a like tesla door hand motor pod? - connect without tools…
Regarding 1:
Yes, it would be possible to print the box. But it’s far too complicated and doesn’t have enough stability. And my printer would also be too small in terms of print space.
Regarding 2:
Since I printed the pod with 7 wall lines (0.4mm x 7), no water penetrates through the PETG. I think a coating is not necessary.
Regarding 3:
I have concerns about the stability and longevity of a printed propeller. In addition, the Fold Prop from Propellerking is of excellent quality.
I would buy the Fold Prop again at any time.
The stability of my pod should be sufficient with an infill of 40%.
But I will still print a pod in ASA-CF.
When my system eventually works in the water, I will test a printed prop.
Many users also use printed props.
Do you think 8s3p is enough torque? Why did you decide on 8s and not 10s or 12s. The higher, power transfer should be more efficient, no?
BTW
I composed here info about 3d printing and materials, I would be glad to receive comments or PR, you can write them in the comments on the page or direct:
