Yea that is neat, I really like the way the FUNJET flies and doubling it's size will give a perfect size for a 14 -18 lb turbine! I have already made the plans and am in the process of cutting out all of the parts, we will have 3-4 months of cruddy winter weatherhere ( northeast US) and it's a perfect time to build. I estimate that it will come out about 12-12.5 lbs dry so vertical performance should be spectacular
