Tougher is finding a UAV with a payload big enough to handle both the fuel and the agent here in the US

If you knew that the "fuel" is 6 to 8 lithium polymer batteries (cell phone batteries) and the "payload" is a 12 to 24 oz. aerosol can, the problem becomes a bit simpler to resolve.

Don't you think?

RC Models. Giant scale competition class. Most of these have 6' wingspans or better. Modifying for GPS control would be every bit as easy as wiring in a Futaba controler is.

$1500 cruise missile. 152" wingspan and is outfitted with two tanks. One for fuel, or for areobatic smoke oil. Could this not also be used to spray and agent over an area?

Not so far fetched at all....

Point taken. The aerosol can only works with some agents, but now I'm splitting hairs.

Your way solves a whole bunch of problems. You don't care where the plane ends up, you don't really care much about range, and you don't have the costs or clandestine deployment problems involved.

My answer was based on Predator type UAV's. Cellphone batteries and aerosol cans won't cut it.
