Flying Fish Jet Drive Build

You are spot on, I see some stress lines on the stator wings already. Your suggestions are very sound. I will make modifications and test some more.

Thanks for all the suggestions!

re-printing now with the new stator.

If you want to know how much, here at 0:40 @Frage is showing a straight forward solution :grinning:

That is genius! I love it.

Looks awesome MauiMan!

Thanks Chris! And thanks for the guidance, your advice is really helpful.

Great. He looks strong Will you share the 3d model

Hi MauiMan,

That is a really professional looking build and by the amount of water you were throwing out of that pool, I bet it will fly!!! I was wondering, do you use gears or have you found the magic motor to do a direct drive? I didn’t see any gearing in your price list. I’m looking to get started and I think I need to find the right motor first.

Thank you for sharing your great build!

Thanks Matt!

I am using the SSS 360 KV Motor direct drive so no gearhead. It draws alot of current so I think a lower KV would be better if you like jets and no gear. I have been in search for a 200-260KV motor with alot of torque but it is very difficult to find. Let me know if you have any luck.

HI

Has anyone tried the 56200 motor with any good results

Very well done, MauiMan, I’m impressed you run a 3d printed impeller. I would pulverize mine one (but probably I push too much rpm). In my build here I started with a fiberglass one and I had to move to carbon fiber.
Do you use any trick?

@Paolo. I am using carbon embedded PLA for 3D print and then I coated it with Epoxy for re-enforcement. it has not broken so far. :sunglasses:

what a great build. Looking forward to see how this motor performs. I’m starting a build and heading in the jet propulsion direction

What’s the outer diameter of your impeller?

I made the same size as the MHZ 64mm impeller.

What kind of thrust and current draw are you getting with your 64mm impeller?

I am not sure of the specific thrust but I was able to ride around on my stomach not flying though. I ordered a new 500kv motor to get more RPMs. I will have better results to share after I upgrade.

Hey guys, I have had many requests for the CAD files I created for my direct jetdrive build so here it is in the original build post above. I have include all parts needed for the jet end including impeller. Make sure you use these components to be successful:

500-1000KV Motor 56mm
300 Amp ESC
6-8AWG wires
Do not Print in PLA
Print in SLS Nylon or something strong

When you say 500-100KV motor do you mean a 500KV motor or a 100KV motor or anything in-between? Didn’t really understand that part.
