Here is a little aerobatic video on CAP 10
It is difficult to initiate a spin with the steering
The triggered barrels are unrealistic.
The gyroscopic torques due to the propeller are not modeled
For me, the aerobatics airplane flight models of Cap10, Extra and Pitts and are just plain wrong. There are limitations of the simulator and the Extra flight performance does IMO exceed the simulator capabilities, but still you can make it as realistic as FS2020 can do.
I am an armchair pilot - this is bad. But I know how to change the FS2020 flight model - this is good. REAL pilots with aerobatics experience please check my aeobatics airplane modifications at http://www.andreadrian.de/FS_2020_sailplanes/index.html and give me feedback.
