CA,

Looks to me like someone in Germany knocked off the plans and changed the name. I've attached a couple of pictures from Zel Ritchie and I'll get one more bit of "proof" when I scan my Orbit Radio ads from 1966. Zel Ritchie and the Phantom IV were placed in the Orbit Proportional ads of that era and you can see it is the very same plane. Good job on asking as there are a LOT of planes that were, let's say, "borrowed"?? Again, I've got some pics to send you...
