Hi Ed,

I use large RC planes for aerial sampling of migrating insects and other organisms in the research mode. Depending on the plane size, we have 18' to 29" dual nets mounted on the plane to sieve the air for insects. The mesh is about window screen size. There is a bit of added drag when these nets are opened aloft. We had to design a rugged but not too heavy gear box to open and close these nets when traveling at 60 mph.
