RE: What jet is this???
that's what I thought at first, but from looking at pics of a starfire it appears that this jet horizontal stab is mounted on towards the top of the rear tube vs. middle like on a starfire. Plus the sep. between the trailing edge of the wing and the leading edge of the horizontal stab seems further then a starfire.
I wonder if this could be one of the older JMP Starfires before YA revised them.
