I would be interested in an Aquila A210 for FSX as well. Haven't been able to locate one yet, though...
So far, the closest thing (and good systems sim) is the Aerosoft DA-20 KatanaX. But it does not have the same response, Vx, Vy, Vg, cruise speed as the Aquila (Aquila typically some 10% higher). Also, the cockpit layout is entirely different (based on a different philosophy), so as a real life PPL "trainer on the side", it won't do. That's why I am alsoo looking for a decent model; I am currently taking flight lessons in an A210 (G500/GTN650 :rolleyes:). I have just soloed (yesterday, to be exact), and I could really do with a flight model that correctly represents the glide behaviour of the A210. I notice that with forced landings I keep overshooting, because my expectations are based on the DA-20 FSX model .
So, to re-iterate the topic starter's question: he's specifically looking for certain aircraft models, like I am looking for the A210 too. Other models may be very much fun to fly, but that was not really the question ...
