In the cfg is -1.0 but how I set it to 10 minutes for ex? or -1.0 means default? so weird

Curious about this as well.

Look in HeliControl Config ..............

"Loot - Time before unlocking CH47 crates": 300.0,

i set mine for 300 (5 mins) as 15 mins is way to long.

Thanks Tom, I just played with config and noticed it was seconds. The -1 threw me off, wasn't sure what it referred to in terms of timeframe. Also, I thought Survey was referring to the time that crates burn after a helo has been shot down. This setting in the config was also at -1, I set it to 300 on my server and the flames run 5 minutes now.
