Hello @ll, A small update for FireFighter X has been released:
You can now fly "lead / birddog" for the AI: you can direct AI firefighters to follow your own aircraft and instruct them to drop retardant on a fire or a specific location. Please note that they are still AI - so they will try to follow your flight path to the best of their abilities, under simulator control (which means, they are not "locked" to your aircraft in any way, they still have a mind of their own).
The issue in P3D 4.x where FPS would plummet when using Bambi Buckets on AI helicopters has been resolved.
The update has been uploaded to the shops just now. Please allow for a couple of days until they deploy them. Best regards
