Flew the DR400, PA28, PA28R, DA20, DA42, and have been flying the Bombardier CRJ 1000 for an airline in Spain for over a year now.
So far, I´ve only tried out the CJ4, Bonanza and King Air. I´m no test pilot, just an every day airline pilot, but out of the 3, I think the Bonanza is the most realistic. I´ve never flown it in real life but it doesn´t feel overpowered, behaves the way a piston aircraft should with its pretty significant torque and so on.
The CJ4 is ridiculously overpowered, again I´ve never flown this type of aircraft but at max takeoff weight, she’ll do 5000 fpm climbs without a problem, to the point that I have to reduce the power to about 60% N1 to get a normal climb rate. A Global Express 5000 might be capable of this, yet even with that type of aircraft I doubt it, but a CJ4 no way…
The way the turbines respond to throttle input is WAY off. In the sim as soon as I push the throttles the turbines react which is really unrealistic. A jet engine has a lot of lag. You push the throttles and depending on the type of jet engine, you sometimes have to wait multiple seconds before the engines spool up. Jet engines don´t react at all the way piston engines do. There´s a pretty significant delay, especially when you´re at idle. The CRJ 1000 takes about 2 to 3 seconds to spool up from idle to 70% N1. You push the throttles and at first nothing appears to be happening. In the sim the CJ4 reacts in a microsecond.
The King Air is a bit more subtle but some things are totally off as well, such as the torque that increases with gaining altitude, forcing me to reduce power while climbing. It´s totally the other way around. You have to add power as you keep ascending to higher altitudes. Can’t remember what else was wrong because I’m spending most of my time in the CJ4 but there were other things.
What is totally off about all 3 aircraft are the spins. I was totally incapable of getting them to enter a spin which is not realistic. I´ve bought MSFS since FS95 and kept buying each new version and when FSX was just left to die I turned to X-plane 10 and was amazed by the flight dynamics, same thing with X-plane 11.
To be clear, I prefer MSFS because it´s more user friendly and grew up with it as a kid and will be sticking to MSFS2020, but I really hope Microsoft will improve the flight dynamics to make it perfect.
Just my two cents
