Hi Charles, Morphing a Dragonfly toward a KR2 is also what I have in mind. I haven't decided on a header tank but I would have hollow wings with fuel-tanks in the inboard leading edge. The LongEz and Cozy have fuel-tanks in the strakes and use a different foam in that area which doesn't behave badly when exposed to leaking aviation fuels. In addition to Dragonfly plans, I have plans for both these canard aircraft too and followed their mail-lists for years but decided they're not for me. I also have the foams and fiberglass for a Cozy which I would utilize. I suspect there are others out there with the same inclination. Tom

I have built a Dragonfly (hasn't flown yet) and found the construction technique to be fast and easy (you have to be fast when applying epoxy). However, I want to start over with a conventional design that fits the requirements of E-LSA. I would like to use the same construction techniques used in the D-fly but do not know what the parameters or results of putting a hollow space inside of a foam core wing would be but think it might be doable as wing tip tanks, just hollow out the outermost 'x' inches of wing and use it as the tank, the least stress place in the wing. I am looking at the KR design as the basis for this plane and soaking up any ideas I can run across to help me out. Perhaps external tip tanks a la T33? I am aware that foam dissolves in gasoline.. _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html
