Vincent,
Recall the motor itself is one whacking big piece of rotating rare earth magnets, so I wouldn't be too worried! Anyway magnets are what I use for both my Nobler and Vector electric ships.

         Where can you get those earth magnets?  Do the "big box" stores carry them?
  Suggestions sure would be 'ppreciated...

I "googled"  'rare earth magnets' and there were several suppliers.  Here is one of the many.

The disk magnets are pretty far down the page.

I have used 3/8" 1/16 x 1/10" in my application. That is what I had available. The prices look pretty cheap, but I didn't check the S&H.

I wonder if a place like Hobby Lobby (not the hobby shop--but the craft store) might have them.

I'm using magnets to hold the hatch on my electric model.  I found the magnets at Radio Shack.  They arent the cheapest place to get them i'm sure, but they are handy if you are in a hurry.  I think I paid 1.99 for a package of 2.

Try www.kjmagnetics.com

That's where I get all of mine. Check out the surplus ones. There are several useful sizes, and the prices are decent too.
