Best of luck to all of you that are building the Great Planes Gee Bee. Mine was powered with an OS 120 four stroke and had the custom Robart struts. Everything went together well except for problems with fitting the bellypan and reassembling the struts inside the installed wheelpants. The end result was a beautiful and unique RC plane. If you take the time to read the user reviews posted in the last couple years, you'll notice everyone raves about the great takeoff and flying characteristics the plane has. I agree with them all BUT.... be warned about what everyone says pertaining to landing problems encountered. After repairing minor cracks and scratches on cowl and wheelpants along with periodic torn covering due to rough landings, I finally conceded the fact that this was going to be a common occurence. I guess I'm too much of a neat freak to put up with that so I removed the engine and radio equipment and gave the plane to another member of our club. He also struggles with landings. Again, I sincerely wish you good luck but suggest you take pictures to remind yourself how nice looking the plane once was.
