Hi Gordon,
A few metres below would be way too close to the rotor wash downdraft. In still conditions rotor wash extends to around 5m below (it produces 7kg of thrust). But for things like sensitive magnetometers it'll be necessary, so a long multi stayed drop line is more than possible.
For gas measurements, above the craft on a tall boom will work fine (induction side is much calmer) I'm especially interested in this as they are about to build a waste incinerator not 5 miles away. "They" say the exhaust gases will be safe but what you suggest is exactly what I want to do. I.e. Fly a 3D grid box downwind of the exhaust stack and monitor various gas levels. I already have the permissions of the farmers that own the land around the site because they are all concerned.
Flying the instruments opens up all sorts of possibilities. And glad to say I found the Espruino, makes it all so easy to throw on some sensors. :)
Cheers
Ian
