You said you don't have a 15? I was planning to use a RedHead 35, but I do have an Enya 19. Do you think the Enya would pull it OK? I built a couple of Sterlings's Flying Fools back when, and it was all the old McCoy could do. They were about the same size, I think, but pretty heavy. At least they sure seemed overweight compared to the other planes I had back then. Thanks for any advice.
