I would be interested to know what, if any, modifications your KR has that might be responsible for its better than average stability?
Ken, I have a stock KR-2S and the modification I've just completed was a spanwise extension of the stock horizontal stabilizer. The extension is 15cm(6in) on either side. I've noticed this mod on an Austrian KR-2 build in 1986. His KR-2 is a single seat because he could not get the stability the authorities wanted. However with the tailvolume increase he managed to get within stability criteria as a single seater. I have experimented with foam and tape before glassing the extensions in place. The result is a trimable KR-2S. My KR now holds trimmed speeds just as Jeff describes. Flying old-fashioned and not being able to afford a fancy GPS a hands-off airplane is easier to navigate with charts....

Is it a KR2 or 2S? Where was your CG vs the aft face of the forward spar (or some other reference) during the recent "hands off" stability check?
