Not the same rotor caps, but otherwise it should be the same as the air cooled Colossus.

10mm shaft is pretty small. But 50kv would be cool.

The shaft is 12mm through the bearings. Here's Aussiejesters CA-120 (35mm stator stack) showing needed mods for traction applications.

ie. replacement of stepped shaft with a 12mm full length shaft and removal of the prop-mount hub and chassis mount plate.
