my config is set as this:

{
  "Block Airdrops spawned by the server": true,
  "Block Cargo Ships spawned by the server": true,
  "Block Chinooks spawned by the server": true,
  "Block Patrol Helicopters spawned by the server": true,
  "Event Timers in seconds": {
    "Airdrop": {
      "Max": 3600.0,
      "Min": 600.0
    },
    "Cargo": {
      "Max": 7200.0,
      "Min": 3600.0
    },
    "Chinook": {
      "Max": 7200.0,
      "Min": 3600.0
    },
    "Helicopter": {
      "Max": 10800.0,
      "Min": 10800.0
    }
  }
}​

but even when it says /heli - 1 hour or so its still spawning almost every 30mins? am i missing something here or is there a bug

same here...

I find adjusting those values does absolutely nothing.  No matter what i set them to, it is ALWAYS 2hours and 29 minutes.  Id use a different plugin.

Heli spawning way to often I am up to every 20 min now but have plugin set for 3600min to 7200 max
