Greetings Ken,Kent is right.... I do have a GN-1. And best of all it will be powered viaCorvair. I bought my '65 110hp Corvair in August and have is about 80%completely converted for aero use.I stretched my fuse, but not because of the 'Vair. There is really no needto do any mods to the fuse if you are going to run a 'vair. The GN-1 wasdesigned to be powered with a C-85. As I recall a C-85 with full eelctricis about 190lbs??The 'vair is about 210lbs. Of course the 'vair is heavier, but let me tellyou a secret.... GN-1's are notorious for being tail heavy and most guys whouse C85's end up making longer engine mounts to get the weight out in thefront. The GN-1 doesn't have the ability of being able to move the centercabanes to change CG. The way it ought to be if you ask me... canting thecabanes forward or backward is the lazy way out of poor planning whenbuilding the plane if you ask me.I strongly suggest you try on a GN-1 for size. The fuse is narrower than aPiet. I was able to sit in one before I built my fuse. I relaized therewas no way in hell my 6'4" body was going to fit. I widened mine 1.75" atthe rear seat and about 1.25" at the firewall. I also stretched mine. Imoved the rear seat back 2.5", moved the firwall forward 1.75" and pushedthe tail post back 1". It was VERY important to leave the upright sticks atthe same dimension where the cabanes and landing gear bolt up to. Keep thatin mine when stretching.There are TONS of pics of my GN-1 during construction at my sitewww.raptoronline.comscroll down to the Aircamper logo and click it.Feel free to email me off list any time if you have questions.DJ Veghwww.raptoronline.comN74DVdvegh(at)imagedv.com----- Original Message -----
