Low down on tightening Graupner 10 x 5 props onto F550 (stock DJI motors)

Hi Olemil, as long as the washer is a snug fit on the prop shaft you should be ok, these washers are mass produced and should be well balanced as long as there are no burs stuck anywhere and the washer is neat and clean and the hole of the washer is in the center. Introducing glue might have its own problems if it is not even all way around. Aluminium or G10 would be lighter if you can get them. Regards - bruce
