Hi Dennis,
Bill's F-4 is Classic legal!
![Grin ;D](https://stunthanger.com/smf/Smileys/classic/grin.gif)
It was published in AAM side by side with Vic Macaluso's F-8 (both were Fox .35 powered! LOL!) in about 1971 (I have the issue, but not handy
![Grin ;D](https://stunthanger.com/smf/Smileys/classic/grin.gif)
). Bill's Phantom was designed/flown before 1970, Vic's Crusader was not.......

The F-4 is a very good flier, somewhat large for the Fox .35 (at least by today's standards). I'd use an Aero Tiger .36, PA ultra light .40, Magnum .36 XL IIS, etc..

AMA has the plans available along with a few other vendors (Randy Smith, Tom Dixon, etc., ??).
