Home Made Flume

haha yea that’s exactly what I had in mind

Thanks for the data! I will post my results once will have some. @VeFoil do you have any feeling of current results on this 6s tests? how much power the motor was able to provide in this case?
This 250kv custom motor, can I buy it somewhere?

The motor will max out and draw its peak current and shaft torque (Nm) and then that’s it. Meaning, the SSS motor did not have enough torque to get the 80mm turning up to speed on 6S, and would not have any more power even if we used 12S. Volts regulate the RPMs mainly, not motor torque.

Typically a lower KV motor of the same diameter will weigh more because the windings are thinner, thus you can coil in more copper, and the more copper you have, the more torque you get. Which is why your 360KV will work slightly better than the SSS 500kv we used.

Yes, you can buy our VeFoil motors. We designed our motor to fit into 2.25" (57.15mm) aluminum tube, its 1+mm larger diameter and longer allowing two main things, a lot more torque, and much better thermal cooling with aluminum tube.

They are built for maximum power and to last in water with Stainless Steel motor case bolts, SS grub shell screws, and high-speed ceramic bearings for low heat, no maintenance, and rust free operation.

Once we finish testing the motor in a few weeks we can do custom KV to fit your needs, and the best part is we can get a motor built and delivered in about 20 days

That sounds good, but keep in mind that most people here have a tight budget.

what are the projected specs amnd pricing on the motor ?

Yup for sure MaxMaker, we took on the task of getting our own motors for many reasons: to cut costs for the build, get something better than stock motors that get rusty bolts and bearings, get more torque at the shaft, remove a couple layers of middlemen marking up prices and almost more importantly get a motor within 3 weeks vs 5-8 weeks from all the other sources.

As you will quickly learn the RC/electronics/motors world is riddled with crazy long waiting times. We are living in On-Demand times… Waiting months for one part is painful and costs valuable time so we have been pushing to change this.

Quick Comparison:
SSS 500KV, 116A, 1.9Nm Torque
SSS 360KV, 93A, 2.0Nm Torque

VeFoil 360KV, 130A, 2.9Nm Torque (52% more torque than SSS 500kv, 45% more than SSS 360kv)
VeFoil 250Kv, 100A, 3.1Nm Torque (63% more torque than SSS 500kv, 55% more than SSS 360kv)

If you are using a reduction gear then torque really isn’t an issue, but if you are building a direct drive with 56mm - 110mm impeller/prop then this torque is required to get the prop RPM and thrust required.

At this point, the motor price should be $225 USD plus shipping and will ship worldwide.
We are still testing for another 2 weeks, if interested PM me.

If i want to order one, delivery by fedex in Bangkok, when can you send me ?

We are still testing for another 2 weeks, if interested PM me please.

Hi @VeFoil. Thank you very much for info sharing! Awaiting for motors final testing! These are great news. We have 2 types of motors already customized for our projects the alien outrunner 100kv and yours. It is great step forward.

Hi @Winging_it, where did you get the model for the boat propeller i been interested in trying out some.

morgansteven,

fancyfoam got it (possibly form this forum) fromw somewhere. He is doing the CAD work and the 3D printing for the test props. I’m sure he’ll be able to share what he has.

Why not make a 100kv motor?

Here is the link to the prop file that we had the most success with.

It was uploaded by Tunnelvision. Here is the link to his first discussion on this prop.

Hey mate. I’ve modelled another prop based on a 4hp yamaha prop. It’s 177mm x 10mm. decent results. Happy to share the model (which is editable to suit your setup).

Aaron

That would be awesome. We are planing on doing a bunch of testing and would like with pitch, diameter and shape.
Can you provide a link to the file? Are you using fusion360?

Hi Mike,

Im not a fan of AutoCAD for 3D solid models. I use onshape (free 100% online-made by some ex soild works guys). Why don’t you give me three of 4 sizes you want and I’ll model them up for you. What file format do you want me to export them as (Exporting Files)?

I am trying different CAD programs to see what I want to use long term so I went ahead and downloaded Onshape. Can you share the file with me? mike@fancyfoam.com
Thanks.
Mike

Hi @tunnelvision. Actually I need help to design the motor mount for sss 360kv and the external Kort gotten from AliExpress of 80mm direct drive. I’m trying to do it with fusion but it is really complicated platform to quickly hands on. I can provide all the required info and dimensions if you can help with the modeling. Thanks a lot anyway to introducing this free tool for the design. Will try it.

Tunnelvision turned me onto Onshape. I like it better than fusion 360. It is free. Give it a try and if you get stuck I can help. Sharing designs is very easy with Onshape as when you share it with me I can modify your model.
Mike

Guys, do you know if its possible to import fusion 360 design into onshape so it can be modified in onshape later?
