Another option is plain old thin CA. First, position the magnets in the proper place, (places?). Stick them in place with a drop of thin CA.

Then, to anchor the magnets, take baking soda out of the kitchen, rotate the outrunner "bell" so the magnet to be glued in place is at the bottom, then fill in between the magnets on either side with the baking soda.

Make absolutely certain that no baking soda pokes out above the magnets!

Then, hit the baking soda with a drop or two of thin CA, enough to "wet" all of the baking soda. Instant concrete, and it is pretty much unaffected by high temperatures. I used this process on a half dozen "Go Brushless" motors, no magnets ever let loose.

Try it on a few scrap pieces of balsa or similar to see how it works before trying it on your motor. (This is an old, old trick)

Also found a number of different types of epoxy at Ace hardware. This stuff comes in a hot dog shaped configuration with the hardener on the inside, and epoxy on the outside (or vice versa?) of the hotdog. Just cut off what you need, then take the chunk and mash it until its all the same color. When mixed, it is very stiff, and will NOT run before it sets.

Probably to heavy for model airplanes, but useful for a lot of other stuff.
