Okay got the fuel tanks coded and setup. It's a little different and more worked out of course, from the 2.20 version. I think that they will function as needed for the helos and such. For the AH-1Z I will have to work on the tanks for that, so that'll be another mod in the future that has to wait for 2.22 to come about and be implemented. Overall I find it weird that A3 is seeing a spike in such development close to Arma 4 being released, but I still have reservations given that it seems like Reforger, so who knows what may happen when it comes out.
