Hey Dave, Thanks for the info, Ya I miss my goldgerg ultimate, sadly it's experation date came up a few years back..... , but Iknow what you mean the seagull doesnt fly quite like it, the goldberg was a bit lighter, heck I ran a os60 on the goldberg for quite some time and it flew great. I will double check the things you mentioned. I still love ultimates though biplanes look so cool in the air.......
