The (CFB 777-10 SP) is a fictional version of the 777, which literally changes, basically everything. The engines that are on the 777-10 SP are way larger than some airplanes diameter( 200 something inches). The landing Gear of the plane has been redesigned to land in military grade conditions. The outer wings can be folded, just like a fighter jet would to reduce space required. noticed any similarities with the 777X? My version and the real life counterpart nearly have the same changes. The fuselarge was initially stretched by 20 feet, but the final stretch was around 40 or more feet. ok enough info, now the for the activation groups. AG-1: Arms the spoilers(Need LandingGears down for it to activate or arm) AG-2,3,4:i forgot what 2 does, but 3 is the landing lights, and 4 is the cabin lights(needs ag8 active) Ag-5:Open front left door( both front doors can be opened by connecting it to the pistons) AG-6 Pushback. AG-7:Da apu on or off. Ag-8:Engines(With start up sounds, but not too realistic), main batt, and the rest of the lights. Trim is well........trim, vtol slide up:fold the wings(the wing decrease is simulated but not realistically i think) Vtol slide down: Flaps. I think the sound the engines make while spooling up is weird, if it is also weird for you, check the inside of the engines and tweak until its perfect for you. Now, enjoy this son of a beast.
