Speedbrakes problem

Hi all and sorry for my poor english!I'm learning to use this wonderfull aircraft, and I've noticed a little problem (I think so but I could be wrong...). I use a separate axis to deploy speedbrakes. It works on the ground. In the air if I deploy them partially, I can also retract them. If I deploy them totally, I can't retract them. I turn back the axis but nothing happen. The only solution I've found is to make a sudden left or right move of the joy (wich is not possible with autopilot, unfortunatly). Does anyone have this kind of issue?Ok, I'll go back flying this masterpiece waiting for an answer.ByeStefano Caspani
