I also have built a super steerman with the capability of having a wing walker. However, I am nervous as to how it will fly with a figure on the top wing. It appears you used a barbie doll which is pretty near scale. I planned to use Ken. So, what can I expect when I place the doll on the top of the wing. I will be taking pictures and I shall send you some. Thank you in advance for your assistnace. Jack
