Whit,
I finished the revised version of the Eindecker with the under cambered wings and took it to the Scale Nats this year. We test flew it there with the G62 and it was grossly underpowered. I added a lot of scale detail and it probably weighs a little more than Art's, but he has a GT80 on his.
I have decided to install a DLE111 this winter and that should do the trick.
I have also decided not to pursue the kit business. It is taking up to much time from my architecture business.
I have several planes on my bucket list and I am only going to do modeling for myself and just enjoy it as a hobby.
Here are some photos of my Eindecker.
