HTD Belt drive mod for MT410 V1

[sissy lettice]

I was working on some projects where I was printing HTD pulleys for belt driven transmissions and decided to try it on my OG MT410 (V1).
She's sooo smooth and quiet now. Been bashing it for about 2 weeks and it's rock solid.
I'm running HTD 5mm pitch belts with pinion:spur ratio @ 14:27
The mod is very simple as the pinion is a stock pulley and the spur is a 3d printed "sleeve" that fits around the center diff casing. Then you install the diff as usual but with the mod-1 gear facing the rear. If you ever need to switch back, it takes about 10 minutes to flip the diff and swap the pinion.

Interesting, that looks pretty cool.

Yea looks very cool. What the advantages other than quieter smoother sound?

Admittedly, I can't report any direct or notable performance advantages (also no disadvantages), but I've only run it at my local skate park as of now.
So maybe the "smooth" acceleration could have an advantage on dirt tracks?
If there are any engineering nerds around here that could speak to advantages and disadvantages of using belt drive vs gear, I'd love to hear about it.

I imagine it will have lower efficiency, similar to belt vs chain driven bicycles.

I noticed there's an official belt drive mod for xmaxx. I wonder why it's considered an upgrade for that particular chassis?
