I'll bet it does. Is the back plate and bearing tube composite too? Or does that transition to metal in there somewhere?
It think it was E-Flite that had or maybe even still have a motor with a plastic base that didn't do well in service. It was on the first generation foam glide that became so popular, really a good plane, but the motor base (it had threaded insert molded in for mouning) would develop cracks over time, probably from the heat.
Those aluminum bearing tubes and backplates are the primary route for gettng heat out of the windings. I always touch that base of the motor first to check for heat.

I usually cut off the backplate, or what I called the guard earlier, for ease of winding. This stator was obviously wound before being pressed into the composite.

I install 2 or ring of 17.8mm diameter x 2.5mm
But better best one 17.8-18 x 3mm.
In EDF with 28mm duct.
In one EDF of 30.5 as XRP 14B is best a thicker ring.
11 turn with 20AWG is easy.
But you can use 21AWG.
This motor is for Wemo mini fan 68mm. to 4-5slipo.
I'm about to RECEIVE one 70mm EDF 10 blades and a 14.
As can'll post the results with the new engine rewind.
