The frame and 3 pt attach I was able to build from scrap that I had collected.
I had to weld the tubing together to get the necessary lengths, but they worked and I think that they will be strong enough. I could not find material to get as tight a fit on the pivot pin as I would have liked, but I believe that it will be adequate for now.
The "F-18-hornet" double tail fin is for the gauge wheels that are in the works. I know that there is no extra bracing on the square tubing of the 3pt mount, but this tubing is fairly heavy wall and I believe that it will work without bracing. Maybe I will be embarrassed!
