There are two holes on the side. Maybe 3d print a inner part and put the 2 screws from the side.
I wont short the shaft of the 80100 motor because I don’t have any machine for doing something like this.
Any ideas? How did you guys mount the prop onto the 80100 motor
they are similar to your (184mm dia): the black on is a 7-1/4 x 6 plastic, the white one is a 7-1/4 x 5 alu… but i didn’t get to test the white one as i printed one that was smaller and much better 80100 direct cooling - #286 by Mat - Builds - FOIL.zone
the printed one is 160mm diameter and works great (see thread above)
