First I'm using a translator so I can say something wrong!
I have a problem that has nothing to do with the plugin, it happens that the minicopters purchased on safezone are coming with 13k of fuel. How do I fix this?

The issue is that the vanilla game uses 20% of the max stack size of low grade when fueling helicopters (not for boats though). Either of the following plugins can solve that.
