If you wanna try VESC despite the stories, note that it had become a lot more user friendly now with VESC-Tool! Auto detection helps a lot to get adequate parameters for your motor.

Yep, gonna have to either cut the frames or adapt a sub frame to it! I've ridden many miles with 2 wheels per skate (analog) to directly feel the difference versus all wheels mounted, really IMHO it is better to keep the middle wheels if you can!

I'll be fabricating a frame for larger wheels.
I skate slalom so the idea of losing the middle wheels is daunting too since I'm only on my middle wheels most of the time.
I'm betting 2 outer wheels only has horrible maneuverability.

Can't help it though, since I'm going the old fashioned mechanical drive train route, I need a ton of space to mount the components.
This is likely going to turn out as a personal use project, commercially it's looking like no way...
This is the beauty of DIY projects though, I make what I want, no matter how much it snubs convention.

I'll post another render soon, I'm on my 3rd design iteration and it's looking like some kind of a motorbike-ish death machine.

Hastily, I've sent my clutch off for fabrication, I was planning to make a 3D printed proof of concept first but my friend who does 3d printing quoted me 1/4 the cost of what my fabricator quoted to make it out of steel, inclusive of latter adjustments to improve free running tolerances.

I'm impressed by these little bldc motors, they put out a lot of horsepower for their miniature size.

Yep ! These are a good choice to start with. I forgot, do you want to FWD, RWD or AWD your skates with the clutch ?

Only RWD or FWD, depends on how it feels when accelerating, that will be a later stage. Currently working with RWD design, just because it seems conventional.
The clutch allows for freewheeling both forwards and backwards.

Small update,

Got my old 3d printer out to make some prototypes.
Getting the printer repaired, set up and calibrated and printed parts to fit with each other took almost all my time till now.

Starting to print a few clutch designs I have for a proof of concept.
