GO to
www.teamdusters.com Hollis Calvert has 2 sizes of the Air Taractor, I am building the 72 inch version.. Also go to
www.airtractor.com and click on the gauge link for funstuff. The version they offer is a fiberglass fuse. I have seen both manufactures kits fly and it's a toss up as to which one you like.
