Hey Donnieman I did a really good look at your Super Ringmaster plan set, really the only item that is the same is the landing gear. The rest is a little different and this kit I am building just might be a tad wider. Hard to tell. But I will.trace the assembly I have. I really like the kit just not too crazy about the soft Balsa. But the only ribs I redid was rib 1.AJ
