That would be the Model Z. Pictured below. It was a replica built by Bill Turner. The plane now resides at the Fantasy of Flight in Polk City Florida.

Jack Devine has a kit, but it might be a little big at 85" and 16-18 lbs.

Adrian Page had a .46 - .55 size kit but he's no longer making kits, but you can check it out here.

Wendell Hostetler has plans, but again it might be a bit big. Wendell will scale the plans to any size you want if you know what scale you need. If so, stick with an even scale for ease of finding fiberglass parts.

The AMA lists only one plan for an RC Model Z with a 47" wing and a .40 size engine.

IF you would settle for an ARF. Kyosho had a .46 size that they no longer offer, but you could watch the auction sites and here on RCU for one. One sold here on RCU 5 days ago for $260.

Well, that's about the extent of my knowlage of available kits, plans and etc. on the Gee Bee Model Z. If I can be of any further help, don't hesitate to ask.

I hope to be starting the Model Y soon and plan to do a build thread in the RC Scale forum.
