Anyone have experience with using Outrunner motors in ducted Fans.
Is there any issue with the Bearing Rigidity? Isn't all the stability placed
on one bearing up front unlike inrunners that have 2 bearings?

THANKS, TOM

Nearly ALL motors have 2 bearings, most are ball......the trend is heading toward outrunners being used more in D/F especially the bigger ones where there is good thrust at lower RPM

I use outrunners in all my EDF models. My motors have ZZ rated bearings good for 70,000 rpm.

Here is one I sell for Alfa models:

I wind nearly all my own EDF Motors all Out runner.
No real problems with bearings , but I find only a small number of ESC's can handle the High RPM .
Largest so far is a double 22mm Stator for the 75mm GWS Fan, the Smallest 14mm dia for the GWS 30 60Grms thrust at 3A
The best!! is a 18mm dia wound hot for the GWS 40 fan, 200 grms at 9A on 3 cells
