The release notes today say: "MiG-21Bis now works in the Persian Gulf."
Mine doesn't crash anymore. Thanks ED and the developer.
edit: Oops, didn't notice others had also mentioned the release notes. Thanks anyway.
I had a similar problem with a CH Pro Throttle. When I 'tuned' the throttle/trust axis in DCS Controls I saw that it never fully went back to zero. So, I had to set a null bit at the end (I ended up using saturation for this I think).
Thanks Splash, that's why it didn't come up for me then I guess. I found that the training missions included with the L39 are interesting anyway so looking at those first.
Thanks WillBillKelso. I had the same problem and following those steps resolved it. But it came back as soon as I mapped the throttle axis again. The throttle has to be at zero and it turns out I had to tune my throttle axis so that there was a blank bit at each end (I forget that the option is called).
Thanks.
