I tore my hair out troubleshooting this, this last week. When you bind the WSO hand controller under f4e pilot axis binds, jester has a hard time locking up targets on the radar and wont properly groundlock. This is even if you have a massive(20) deadzone on the axis.
The wso bind is for the pavetack control from the front seat. When bugged on a DT, jester will say groundlock but it has no range info and the bombs wont release or release 2000ft long.
I have to chose either pavetack control or being able to A2A and DiveToss.
Just a heads up.
