I have the Mig 21 since about 3 years and flew about 100 hours (must look in my logbook and will with an edit give the exact data) and enjoyed her a lot: trained to navigate and RTB in bad weather conditions.
Now I payed maybe Eur 40,-- for her, so I think that the cost was about Eur 0,40 / hour: surely nothing to complain :)
Now I understand, that there are still some issues and I read that the devs are working on it.
But then that complaining of these customers who payed some money (sure not that much) and are going to bash the devs and that bashing get worse all the time: I HATE IT!
Must be very demotivating for the devs!
To the devs: I thank you for developing the Mig 21: she is a fantastic aircraft and I have enjoyed her a lot and hope to do that some more in the future :)
