Ah sorry I didn't communicate very well, I've had my PPL for about a year now. That's awesome that you trained in the Katana, I still haven't gotten to fly any Diamonds yet but they look absolutely gorgeous. Plus I'll bet the stick and throttle quadrant feel a lot more fun than the yoke and push-lever things for throttle and mixture in the Cessnas. Actually all I've flown are Cessna 152s and 172s, I really gotta branch out one of these days. Have you had a shot at flying the DA-40 yet? That thing is pretty much my dream plane.
Ah, kewl, my bad

. I flew 152s and 172s, and yea, the Diamond's stick/throttle quadrant is a lot more fun than the yolk/push throttle combo.

The Diamond's also faster, and a lot more responsive (I had trouble doing some maneuvers because the plane was just so damn eager to fly, it's easy to come in high, or when doing a soft field take-off, pull up too early - you don't stall, you just don't demonstrate flying in ground effect long enough). And yep, I've flown the 40 when the 20 was down for maintenance. Basically it's a four seat version of the 20 to me - it's responsive and nice, but noticeably heavier. The GARMIN 1000 glass cockpit is a real treat though
