L-39 control axes have gone wonky

[Svsmokey]

It seems that the pitch and roll axes have some kind of bias in them that i thus far have not been able to resolve . It is the only aircraft affected by this condition , and the bias appears to be un-trimmable in-game . I really want to fix this as it is a particularly good aircraft to fly in VR due to the oversized instrumentation (Plus it's a great aircraft) . Is there a lua i can edit somewhere ? The only one i found in saved games seems to be for bindings only ?
