As Emmerson points out, drones ain't about to go away. See, from National Defense: Worldwide, Drones Are in High Demand (May 2013, by Dan Parsons), as illustrated by this Brazilian example:
Brazil is not an established drone player - yet:

but, it certainly looks like a strong comer. See, Merco Press, Brazil and Israeli companies join to develop unmanned aircraft for border control - Brazilian defence contractor Avibras will join plane maker Embraer SA and the local unit of Israeli Defence Company Elbit Systems in developing unmanned aircraft in Brazil, the companies said on Tuesday (February 6, 2013).
Will drones be effective in a "rain forest" ? That is beyond my expertise; so, I leave it to someone else to pick up that part of the thread. If they are effective for recon, intel, etc., in the "rain forest"; one wonders how long it will take for them to be weaponized. Crossbow, fusil, etc.
