Dude that’s awesome, thanks! 20S?

Plan to go 18s2p molis p42a, i think that will be faster that I dare to ride, ow is not a speedy machine.

Let’s go!!!

XR battery box scan

Oh wow, thanks mate, now that will come handy! I assume you can fit the 18s2p 21700 in the box then?

No way to fit 36pcs 21700 in that box without modding it before printing

Don’t buy new, look for hardware 4209, not higher recommended

Yeah, that’s what I thought, I also took some measurements from your scan. What’s your plan with 21700 though?

That’s a good point, even though I’m replacing the hardware (so I was kinda ignoring this aspect), apparently 4210 controller just won’t work with any BMS other that the one it came with (now that’s a stab in the back by FM). Even though I’m selling both, it won’t sell well… Thanks. I’m in Europe though and I don’t see many XRs for sale, that’s why I came with this plan.

The ow plus is exactly same platform, same motor, same controller, smaller battery box (still fitting 14s3p,20s2p 18650) but if you gonna use 21700 you have to print a new battery box.

Yeah I know, but it won’t fit the rails height-wise, so I assume you’ll have it protruding 5-6 mm more on the bottom. If you ride carefully I guess it may be fine, but then it’s 3d printed and the flat thin bottom might be prone to cracking? Just me applying armchair engineering, no experience.

I’m currently planning for 18650 20s3p (14s in battery box and 6s in controller box), and I’m gonna use float plates.

The rails are also the same, the only difference is the bigger battery box and the rear bumper.
I plan to make deeper like 3~4mm and mill the difference on the float plates, so visually will not be a difference

Just showing that I can customize the device’s name when it shows up on the vesc app. Was a learning curve to figure out how to modify the nrf52 code but beating my head against the keyboard for 2 days did the trick

I find this solves a great many of life’s problems.

So in related news, I’ve been moving through the manufacturing process. It’s definitely a lot to chew and handle as an individual with a whole nother full time job and 42 other projects i’ve been ignoring. One of these days I’ll learn and get help…or something.

I’m starting off with a small batch of 100 units being made. I know that kinda sucks but keeping it small keeps it manageable and safe in a few different ways.

  1. I don’t have the capital for a higher amount. This is all I can afford until some revenue comes in from this first batch and maybe some other funding from other sources besides myself.

  2. Containment of issues/imperfections. I’m not by any means promising a perfect and polished product of what you might be used to seeing. The case could be 3D printed, the heatsink a little weird, and some other oddities may manifest and be noticeable. Rather than this applying to a mountain of stock, it’ll ideally only apply to this first batch. I get better as I go and get the design a whole more and more polished. Functionally speaking, I believe it’s good to go.

  3. I have no idea of actual demand. I’d like to think these will fly off the shelf but idk for sure. These could sit around my garage for a year waiting for someone to claim them. This small batch will help me gauge demand, gauge the market, and give me an idea of how many to get for the next round.

  4. I’m Learning the ropes of a business and manufacturing. I’m a dirty garage troll, not a suit-clad smooth talker that cares about fancy things like marketing and maximized sales. The goal is for me to learn this stuff first hand and then eventually work up to being a suit-clad dirty garage troll…or something.

So exciting to see this getting ready to launch!

I think your first step should be a new thread. You can use it to whip up excitement about this product (folks love shinies, especially HV ESC’s) as well as gauge interest. Hell, maybe even a poll. Plus it will allow you to gather all the info that is scattered throughout this 900 post long thread into a more digestable product page.

I think that will go a long way towards spreading awareness of this awesome ESC :smiley:

I think you’re right. This thread has changed and evolved as I worked through and developed my controllers. One specific to the little FOCer would help keep things focused.

For what it’s worth, I’ll take at least one. I’ve been looking for something to work with that can replace a FM controller, so I can just graft the motor onto it and build my own battery, leaving a Onewheel shell that I can repair myself without being tied down. So, supporting a project that can lead to that is certainly something I’d like to do.

Also, not to toot my own horn, but making a video called ā€œFix ANY Onewheel!? Little FOCer Install DIY XRā€ or something would probably help to move any of the dead stock you’re left over with. 3D printed cases and all. :eyes:

I’ll take one yesterday :grin:
Maybe to help with funds we can prƩ order one?
