Hi dear Jet-Pack!
I have been using your mod for a long time. I changed the file C172mod.tmd a little bit so that everything is now off, even the main fuel valve (fireproof) is closed. I regularly change in this file the weight of the fuselage and the degree of filling of the fuel tanks. This can be done for flights from 1 hour to 4 hours or for different passengers with their luggage.
I noticed changes in the new version of FS2 in this file inside the landing gears and, most importantly, in the aerodynamics of the fuselage and in airfoiles. Will you make these changes in your mod? Do you approve of them? And then we'd better wait for the new version of the mod, how do you think?
