I did my preliminary weight and balance last night. I do not have wings builtbut I estimated thier finished weights and arm. I needed to figure this out soI can design my engine mount.I levelled the airframe and placed scales under each wheel with me sitting in therear hole. I got 140 on each main and 115 on the tail. I then figured inwing weight and other misc. items like avionics/instruments control cables, covering,paint. Using my firewall as the datum I determined that the center ofmass of my Corvair would be about 19" in front of the datum. I then figuredall the firewall forward items and did the final calculation.Wow! I need my GN-1 to balance at 36" aft of the datum.... my calculations camein at 35.5" Looks like I did my math properly when I stretched my fuse andmoved the rear seat. Hopefully my estimations of all items I don't have wereclose. In any case as long as I can manage about 1" or 2" nose heavy I canalways add 5lb to the tail. no biggie.by the way, my estimated empty weight is going to be around 630-660lb. Rightwhere I had hoped.Now I can begin engine mount construction.DJ Veghwww.imagedv.com/aircamperN74DV_=This email has been scanned for known viruses and made safe for viewing by Half Price Hosting, a leading email and web hosting provider.

Subject: Re: Pietenpol-List: w&b success!DJ:If you can't move the wing and must add weight, don't use dead lead weight. Put together a tool kit, spare tire and or wheel, battery, spare climbing propeller or something remotely useful in case of an emergency. In the old daysthese things were built into the design.Just a thought,Max________________________________________________________________________________
