Goodness my name mentioned again!!   Sorry for the delay in information, but design now finalised.  Had I copied tracys it would have been much cheaper, but that is now history.  The delay at the moment is the flexdrive.  In order to keep that price down I went with urethane which lasted only a few hours before degrading.  Then went back to rubber only to get a dodgy job done despite detailed instructions to the manufacturer.  It was only after I politely informed him that this spins at 8000 revs that his brain focused. That was before Christmas.  It is now Feb and I just got a replacement which looks good.  Now to mount all up again and test the rubber flexdrive.  Most info is on the Rotarpower web site.  I repeat this PSRU will not be the cheap alternative as the nut that holds the prop shaft on is listed at $150! I think they get their prices from a phone book.  My machinist keeps asking why I continually go on about cost.  His argument is  "It is what it is". In other words,  "I have enough work so I really don't care!!"  So far the progress.  Neil.

Can anyone tell me what happened to this?  Last I knew Tracey handed this over to the Cozy Girrls.  I see images of what appears to be this PSRU on their website yet, their website appears quite inactive based on the dates posted for updates.
