Hello All, After installing v2.4 for both 727-100 and 727-200 exp pack,  I noticed that when using the pitch controller for climb and descent there is no vertical control.  I turn off alt hold in level flight and try to adjust vs but there is no response.  Also  when i uninstalled the b727-100 I lost a virtual cockpit mod that kept the AP from floating, does anyone know where i can find this thanx EC

What version of FSX are you running?   On my setup, the autopilot pitch control did not work until I purchased and installed FSX Acceleration.   This issue is documented.  Captain Sim put out a downloadable "fix" that did not work for me.  It caused the yoke to thrash wildly back and forth.
