I have converted a 747 fire plane for FiveM!
You can also press SPACE , Right mouse or A on the controller to drop water.
Add the folder “fireplanebig” into your resource folder.
Add “start fireplanebig" to the server.cfg and restart the server.
The spawncode for the helicopter is “747fire”
I did not make this and do not take credit for it, I simply just converted it into a FiveM resource.
Hope you all enjoy.
