I don't see how this project is going to move forward. If its true that the J/FC-31 is just a tech demo to show off for potential foreign buyers. Then we are going to see this single bird flying around for a long time and it maybe the only one there ever will be. Someone has to pay for the second prototype and the development of its radar and avionic suite. Either the SAC is going to pay out of its own pocket or the PLAAF is going to pay for it. Because no one abroad will pay for it. If the one is unable and the other is unwilling then the J/FC-31 is just going to be one of many in a long line of failed projects.
