Is there any benefit to placing a heli-pad in range of of Monkey Village? In other words, can you get upgrades for cheaper and does your helicopter get camo-killing ability when the village is upgraded to Radar Scanner?
Yes, the Heli-Pilot gains camo-detection if Monkey Village is upgraded to Radar Scanner. It probably gains camo-detection for the Heli-Pilot tower itself, so wherever you move the Heli-Pilot helicopter, it will still have camo-detection regardless. Out of interest, it probably does not automatically gain camo-detection if it merely reaches a Monkey Village with Radar Scanner.
