I own a 1979 C-23 Sundowner (180 hp). It really is an easy bird to fly.
I happen to own one of the rare aerobatic certified models so I can have some fun with it.
It has fairly quick ailerons. Beware of CofG issues; they are nose-heavy. Full fuel and two big guys up front will put you outside the forward limit of the CofG envelope.
It has a reputation of being able to "bite" when landing, being subjected to porpoising. This is less of an issue with the aerobatic models: more weight in the tail, and a leading edge fillet on the stabilator at the fuselage give more pitch authority on the aerobats. It has never been an issue with me.
It requires good speed control on approach or else it will float forever. It is like an airliner in one respect, it prefers power-on stabilized approaches. Use 80 knots no flaps and 1st notch, 75 knots for two notches of flap, 70 knots for full flap approaches (which I tend to avoid for reasons mentioned elsewhere). At flare, hold it off a couple of feet above the runway, as speed bleeds off, keep pulling and the stall honker will go off, and it will plop down nicely on the mains. Hold the nose off until she quits flying completely.
On landing, the placard on the instrument panel that says "raise flaps to increase brake effectiveness" means just what it says. Make a reflex to raise the flaps as soon as all three wheels are on the ground to increase weight on the mains (for braking), and to reduce the potential for wheelbarrowing.
Overall it is a very comfortable aircraft. Not overly quick; you'll see about 105 knots indicated; at 7500 ft you might be lucky to have that true out to 115-120 knots. Very roomy cabin. It will carry a decent load. Figure on nearly 6 hours endurance with full tanks at economic cruise settings, so you can plan for 5 hours and have a comfortable reserve. Good large luggage compartment, two doors.
With the aerobat version you can have fun with your flying mate in the morning, and take the family touring in the afternoon.
That's all I can think of for now. Mine is in the shop right now getting some winter TLC; I plan on being in the air again the first week in April.
