Heath +++++++++++++++++++++++++++++++++++++++++++++++++++++ Dan, I'm not sure the two are related. With that said, I don't see the Zenair upside down airfoil on the horizontal stab working on the KR series without some critical engineering being done. Our speed range is much greater than the Zenair series and might require the airfoil to be adjustable for proper loading. Also, doesn't the Zenair series use a full flying stabilator? But hey, I'm only a hight school physics C student and that was over 40 years ago. I think even some of the laws of physics have changed since then. :-) Remember, the moon was made of cheese, the Corvair was unsafe at any speed, yada, yada, yada,..........................
