This is an edit of the ven2s edit of pplace's JU-87G

All I have done is to set up machine guns on the model as such:

landing gear switch fires the 37mm pom-pom guns
3pos switch down fires the wing mounted MG pair
3pos switch up fires the rear guns

Nothing special, but a bit of fun if you want to practice some tank busting but can't be bothered to set up the weapons yourself
