RE: 20 Size Kwik Fly
I believe it was Midwest that had a kit called the FleaFly + 10. It was Phil's design just upsized a bit. I have one built from the kit from years ago. I should say had one since I gave it to a friend and it is still flying as well as it ever did. With the layout of the airplane it will turn out well. With modern equipment and great servos it will be even better. It should work great.
