Yeah, I have outlaid a weight guide to try to stick of an AUW or around 1.25kg, this is the same as the sebart kat of the same size. I will weigh all the materials to get a good idea of what is possible, and also weigh the components during each stage of construction to see how close/far off the guide I am. I really like the Idea of the depron skinned wing and will look into that. I have been thinking and come up with an idea for the wing and would appreciate some feedback on it, it may well be really stupid but it seems to make sense to me. The idea is that if I were to foam cut the wing I would put a template of the NACA0012 at the root end of the foam and a smaller NACA0009 at the tip end of the foam block, I figure this would create both a tapered cord and a tapered wing thickness whilst giving me the best of both airfoils. One issue I thought of is the fact that this may create a wing that is more likely to tip stall which would not be good. Not sure if this is the way to go about it but was just an idea. I was also thinking about cutting lightening holes into the blue foam with a dremel router attachment , could always skin the wing with 2mm depron after than. Well at the moment these are all just ideas and would appreciate your thoughts on them.
