I never flew them either but I heard enough about them to know to stay away from them.
They have nothing for a payload. Only about 500lbs including fuel. The C1 does a little better then the Rotax engined version.
The nose wheel is free castoring. This means that you spend more for brakes and it is more time consuming to taxi in a crosswind.
They are tempature limited to heat. Judging from you address I don't think this will be a problem where you are but I know that in Phoeniz, AZ in summer the Katanas had to be on the ground before 10 am in the summer. Or else the fuselage would be over temp and ruined.
In cold weather it is physically impossible to do a power on stall in the aircraft.
While UND had theirs they did have a problem with spins. At about the third spin the engine would fuel starve.
Just before I left North Dakota, UND grounded their entire Katana fleet. They didn't like the idea of the wood props delaminating. Dimond did try and blame it on the UND mechanics not torquing the props every two weeks.
Either way. I just heard from somebody still down there that they did finally get rid of their feet in favor of Piper Warriers. A much better aircraft.
OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.
