I use my WildHawk for testing UAV code as well as just for fun flights when I am out and about (where I don't mind a crash here and there). I am now working on finding a battery system that will give me huge flight time and I was in need of expanding the fuselage to hold these new batteries as I test. This is a simple mod with function over design in mind - but I figured I would post this since the WildHawk is a popular platform and this is a easy modification. The added weight ended up being 18.6 grams.
