what do I have to do so that the Ch47 on the oil rig destroys the mini and scrap copter again? I have already tried the following: "ch47 can hurt minicopter", "ch47 can hurt Scrapcopter", but doesn't work. Can someone help me please?

those entities would need to be in an entity group in order to work. also Scrapcopter is technically ScrapTransportHelicopter

    {
      "name": "mini",
      "members": "minicopter.entity",
      "exclusions": ""
    },
    {
      "name": "scrapheli",
      "members": "ScrapTransportHelicopter",
      "exclusions": ""
    },​
    {
      "name": "ch47",
      "members": "ch47.entity",
      "exclusions": ""
    },

"ch47 can hurt mini",
"ch47 can hurt scrapheli",​

Thanks for your help. I entered it as written. But it doesn't work. I'm doing something wrong On the oil platform. The ch47 lands on the Scrapheli or Mini and tips over. Would you please take a look at this?

I don't know then. you will need to trace it. 

"Trace To Player Console": true,
"Trace To Server Console": true,
"Maximum Distance From Player To Trace": 200.0​
