I scratch build radio controlled fixed wing aircraft and I'm currently working on a large scale VTOL Harrier GR9 jump jet.
I have found this 175mm 12 blade EDF propeller and would like to know how I can get information on getting this edf propeller manufactured and what would be the strongest material suited to with stand very high rpm's.
Thanks
Kenny
