I have thought about doing a rotary, and I will. But one of the coolest aspects of White Pass rotary #1 is that it was modified to all metal. And those MTH rotaries are wood sided. I know my gp-40 isn't prototypical. But I want to do a really sweet model of rotary #1. I'm friends with the former rotary fleet pilot and I would love to show it to him one day. Heck maybe I'll make two and give him one.
