I guess that, more than anything, I was trying to figure out how Rand and Robinson arrived at their published CG range
+++++++++++++++ Hey Oscar I found it interesting that your extrapolation came out within 1/2" of the RR numbers - almost as it they had also ignored the influence of the tapered outboard panels. Every informed opinion / pilot report that I have seen strongly suggests the same thing - the airplane gets unhappy with the CG in aft few inches of the range indicated by the designer. Maybe if the planform and true MAC were taken into consideration, the calculated CG range would be more acceptable. Take care Steve J PS - The Pete looks stunning - did it get dinged before or after you bought it?
