I'm working with a tested psru that is designed for the rotary. Tested for torsional vibration. All orders out of the RPM range for normal operation. (2 rotor) It works and we can prove it. The problem is how much to invest in building it? How many takers are there for a $4000 psru? For a $3000 one? I want to know if there is anyone ready to go for a professionally designed and tested unit. Not helical auto parts. Purpose built?
