I know my park flyer uses one that looks similar to this. I'm sure there are some good airplane applications. Direct drive for props so you dont need any gears to crunch under all that brushless power. I'm sure you could use one in a truck application that is direct drive also (no tranny). Lots of cool stuff.
Care to declassify any other specs? Power handling, lamination thickness, magnet grade, etc. ??
Similar to all Castle motors -- .20mm laminations, M19 grade or better, magnet grades will vary depending on application, but we will use the best quality magnets available, Power handling better than any other outrunners that are similar in size (we were pushing some 30mm motors above 1000 watts burst this weekend...)
