OK, since it’s the holidays, I had a bit more time to test, so think I’ve found the problem. It looks like it’s somehow multiple buttons or axis which was assigned to a single function. In My case I had the reverse throttle assigned to the reverse trust hold + the axis. I think it was resulting in generating some kind of conflict once the trust reversers were activated, hence the problem with the TBM and not with other planes. I was able to reproduce the error and reconfigure the control properly. So far the problem is gone. So I think it’s worth it to check the key/binding assignments. For me, the problem seems to be resolved unless I post back. Cheers!
