Fellas...
Something to keep in mind. Once I get the newest Sludge revision out, the flight model will be far more realistic (responsiveness). Quite simply, you wont be able to do a aileron/barrel roll while in a dirty landing configuration. When at low speed, you'll get added rudder responsiveness, but far less aileron response, so the roll rate will be dialed back when in the low/slow regime... as it should be. Also, I'm pretty close to NOT needing a G-limiter.XML 'cause of the new response curves set in the .AIR file. Right now, its to the point where I can do a FULL BACK stick pull at 500 KIAS and still only get 6.5 Gs. I'll tweak it a little more to get 7.0 or closer to 7.5 but its feeling really good right now, in test flights.
So for right now, I'd say go ahead and use what Letourn said... if that helps with your x52. Just keep in mind, once I get this new Sludge out, go back to FULL RESPONSIVENESS and ONE or TWO notches from the left (ZERO) on the NULL ZONE settings. This will ensure you get the whole range from your stick but you'll still not be able to OVER-G the jet and you'll get that slow banking feel when dirty. No more double aileron rolls while dirty.
