Hey, I have been having some problems flying the Su-25t. Every now and then the plane can't dive. When this happens I can turn left, right and up just fine but the stick won't go forward unless I trim it forward. And even after trimming is forward it usually gets screwed up again and I can't dive anymore. Also, after using the autopilot and then turning it off my plane often banks hard on the x axis and I have to trim it. Is this normal? I've never had any problems like this flying the A-10C. Oh, and I use a keyboard. Any help would be nice.
