To Domenic BellissimoDomenic:I was reviewing the pictures of your Piet on Richard DeCosta's website and noticed that you're using forced air coolingfor your corvair engine. How has that worked out for you and have you takenany temperature readings? Beautiful work, by the way. Also, do you haveany kind of estimate as to how much horsepower you are developing - that isa 110 engine isn't it?Mark BoyntonPhoenix, AZ________________________________________________________________________________

Hi Peter:That's too bad about Vertical Systems. I'm afraid I'm stumped about what todo. Does anybody out there know what happened to the company VerticalSystems. They're the ones who marketed the plans for converting the Corvairengine to use the Rinker propeller speed reduction unit. They were activeon the web as late as October of last year, but seem to have disappearedsince then.
