Hello everyone, I am wanting to get started on a 3 rotor 12A (18A). I have most of the easy to get parts. Now its time to get an e-shaft, long bolts, and dowels made. Is there any companys in the US who makes e-shafts with counter weights for 12A based engines? Any build imput would be nice, I have built a rotary before, now I want a challange, I know a 20b would probably be cheaper but that is not what I want.
