Same here.

My FFB2 slackens when I fire.

Happened in an offline test mission I built in the FMB.

Bump - still happens with TF 4.3... I hope anybody of the team reads this* and eventually they might get it fixed. I'll stay grounded as long as this crap is not fixed. Sorry for the lang, but this is how it is, any other words would not be appropriate.

*maybe I'll sign up on the ATAG forums, but not now :D
