I got a email from GMP a little over a year ago i think it was about Missouri Armada P-51D Mustang Mast (antenna)they made and they told me it was a error made at the China factory. They were only suppose to take the radio cable off not the Mast
The Missouri Armada had the Mast on the P-51D in this photo.
