    FTFC20 SPAD XIII designed by Zephyr1

    My entry into this challenge will be a Spad XIII. The initial plans call for a 30in wingspan, and that's what I am going to be doing initially. However I do plan on scaling it up to near a 40in wingspan in line with Ben's PT-17. I usually design a lot of EDFs, so it will be fun to do something...
