Here is an image generated from the mechanical drawing. Hope that is what you were asking for?

Yes, but poor quality, cannot see information. Do you have it bigger size?

The file I attached was higher quality, but it made it small for some reason.

I got the battery hooked up to the charger today.

Pretty happy with the result.
It's running a balance routine now and I'm going to let it run overnight with a fan blowing on the bms.

This weekend I hope to have the 3d printed mock-up of the swingarm adapter so I can mount the wheel to it and hook the fully charged battery up to the controller and run another full speed test.

I think the 3d printed part should hold if I gradually ease on the throttle.

Also, my electric cable throttle adapter came in:

I'll be hooking that up pretty soon. I'll upload some pictures when I do.

How much does that motor weigh?

I haven't weighed it yet, but I would guess around 75lbs. It's pretty heavy.
A lot of unsprung weight, I know, but I don't plan on taking it to the track so I'm not particularly worried about it.

I test fitted the 3d printed swingarm adapter today.
Everything seems to fit pretty nicely!

Scratch that. I got the other half printed, and it does not fit.
Time to make V2!
I think I neglected to account for the thickness of the walls of the swingarm itself in my match and measurements.

It will fit fine if you can take the wheel off before install. It looks to me that the swing arm will clamp down on it.
You can add a shim if its too far out. Maybe the hub spacers have to be re-made a notch wider?

I re-did the 3d design already, it only took a few minutes.
That's why I made it out of plastic the first time; so that I could test fit before having it machined out of aluminum.
Now I just have to wait for it to print again.

Update time again!
I mounted everything up temporarily:

I definitely need longer shocks, but I am really happy with how it is looking so far!
In other news, my brake rotor, caliper, and the holder bracket all arrived:

The axle does not fit, but I knew it would not fit when I ordered it. I need to have the axle hole bored out by another 5mm (out to 25mm)
Things are looking promising!
I have some work to do to get the swingarm mounted properly, but I have a plan.
I'll post more pictures when I get that done.
