Coos, perhaps start by letting us know what the overall weight is of this items you've got. Also a good way to look at what size to make this one is to look at other designs using the same power unit as to wing area and weight.
Same for the duct inlet and outlet areas. For stuff like this it's nice to plagarize from other successful designs if you can't get any meaningful data from the maker.
At this time, I do not have an estimate as to overall weight as mentioned.
I do know the folks at Kress had one problematic time in getting the proper inlet and outlet sizes. One affects the other.
