I was able to find some aluminum 5mm bore gt2 pulleys. This would at least allow the use of the stock motor adapter and 5mm long shaft motors w/o mods.
Many tooth counts were available including some higher count pulleys required to run larger lower kv motors.

Not sure how strong they will be Or what kind of wear they will show, going to look for some made of stronger materials. Order what I can and see what happens.

After a little more searching I did find 12t, 14t, and 16t 5mm shaft, 6mm belt, dual flange, in aluminum only, most common is the 20t variety might have to switch to a 600kv 600 class motor on 7c, running 515mm blades.

GT2 is 2mm-pitch belt. You need 3mm-pitch belt for Protos, I think SM3.

Shoot I bet I got the 2mm pitch gt2 pulley not a 3mm pitch gt2. That sucks.

Yep came in today and it was 2mm pitch
