Mark L., You reported an all up engine weight of about 250 lbs for the Corvair in your KR. What moment did you use? Say from the firewall? I assume this does not include the prop and spinner, cowl etc...???
Also, I like your streamline spinner/cowl, but notice from your web site that you essentially made your own custom spinner. I'd like to get your same look, but do not trust myself fabricating a part that is required to spin thousands of times a minute. Since the time you made yours, have you found a commercially available spinner that might do the trick? If you were to do it over again, what would you do? What is the diameter of your spinner at the cowl? thanks, Scott
