Have you ever run into the problem that your chosen outrunner diameter is too big to fit into the nose of your sailplane; or would you like to power your sailplane without cutting the nose off the fuselage?
Maybe this will help.

The bearing housing contains 2 ball bearings on the output end, bringing the bearing total to 5 ball bearings supporting the motor shaft (see exploded veiw on the pics above).
