I do not know how much my tail weight is, but I am currently flying with a 28 percent CG.  It seems to fly very good.  When I first tested it a few years ago, it was at 33 percent.  It was awful.  I was wondering if you know how most Kolbers set up their CG.  Maybe the ideal CG is 30 percent.  Suggestions are welcomed.   Vic in Sacramento

 Vic,

 

 I haven't had my 503 powered Firestar II for long, but it flies great at typically 34 to 35 percent CG which is near the aft limit of 37.  You need to be careful how you calculate percent CG, however.   My plans (1996 vintage) say to use a wing chord of 64 inches, so I divide by 64 to get a percent value.  The actual wing chord is about 50 inches not including the ailerons and 62 inches with.  I suspect the 64 number is the wing chord based on the theoretical wing section which would have a sharp trailing edge.
