Lockheed C-5 Galaxy

26.9k Sunnyskies  7.1 years ago

The venerable C-5 Galaxy has been in service since the 1970s, roaring across the globe carrying anything the US military could think to fit within its spacious cargo hold. From main battle tanks, to Stallion helicopters, if you could fit it through the doors, there was nothing the mighty Galaxy couldn't get off the ground. The C-5's distinguishing features include its drive-through cargo deck with gaping entrances in the front and rear, massive 28-wheeled landing gear with kneeling capability, and its unforgettable towering T-tail that dwarfs everything on the tarmac. Don't expect sportscar handling when at the controls of this behemoth. It flies like a 300 ton plane could be expected to fly. Though it has its share of counterparts and Ukrainian copycats, nothing can compare to the decades of endless tireless service this mammoth workhorse has provided for the brave men and women of the US armed forces and its many allies. Accept no substitutes!

Talking about the model itself now, many features are included here. Notably the landing gear, which pivots before it retracts. There are also flaps (which have little to no effect on the massive plane's flying), spoilers (ditto), thrust reversers, lights and landing lamps, and a multitude of cosmetic features. This is in fact the highest part count I have ever achieved during one of my builds, and actually exceeds my comfort zone of <300 parts. The scale is 1:1 with a very carefully matched shape based on a technical drawing. The fuselage is solid, and there are no cargo doors, as a project like that is better done by someone with patience, and a computer fast enough to handle all those parts. There are no leading-edge slats, as I still cannot for the life of me figure out how to implement those on a swept and dihedraled wing.

Handling-wise, the plane is pretty responsive, and flies pretty well. It will rotate as early as 80 mph, and lift off around 130 mph, and is safe to land a little slower than that. It takes a pretty long time to climb, but obtains a pretty impressive cruise once high enough and level. Flaps and spoilers don't do much, but still look cool (which is the most important thing). The plane has an easy time of stopping after landing, as 28 wheels exert a lot of braking force, and the thrust reverser is there.

Operation of systems is simple.
VTOL down is the control for flaps, spoilers, and reverse thrust.
Flaps are AG1. Spoilers are AG2. And reverse thrust is AG3.
AG4 turns on the lights, and AG5 turns on the landing lamps, and wing inspection lights.
AG8 allows the landing gear trucks to pivot, so to get a realistic retract and extension, deactivate AG8 after retract, and activate it again after the trucks have cleared the fuselage on extension.
Deactivating AG8 also prevents the noseweel from turning with yaw inputs, so you should always fly with AG8 off when landing gear is retracted.
Avoid landing with the landing gear still pivoted sideways. You will have a bad time.

I also welcome anyone to make modifications and improvements to the design. Just be sure to be polite and use the successor system.

    @Gameboy21 Yeah, it's like a C-5A, but with CF6s instead of TF39s.

    @Sunnyskies do think you can help me out? Me and a few others are in the process of making the C-5M Super Galaxy.

    @thesimpleone Feel free.
    I don't mind people using my parts.
    Take anything you like.

    May I use the wheels on future project?

    If/when youdo could you possibly make a version with some sort of bomb like the moab? @Sunnyskies

    @StandTall I could probably rework the plane as one with a detailed interior. It would probably have a few hundred more parts though. I would need time also. I'm much too busy.

    @Sunnyskies i hope you add a realistic load like a moab or a nuke or a tank or something that we can chuck out the back of thy plane

    @Sunnyskies Yep but i hope they add a realistic load to the thing

    Holy Hell this thing is really good at crash landing too! i plowed it into the ground at like 170 and it did not do nothing at all

    @ChiChiWerx True enough. Though the time-to-altitude (something the C-5 is famous for) is really sluggish on this model, the cruising speed at its most efficient altitude IS pretty good. Approximating real-life handling characteristics with SP's odd physics model is quite the challenge.

    @Sunnyskies maybe just a little, buuuuut, 200 mph and 10 degrees nose up at 500,000 lbs is probably close (don’t know for sure, never flew the Galaxy). Plus I’m sure the C-5 doesn’t true out at much more than 500 knots, though SP works in mph (dumb).

    @ChiChiWerx I probably should have uprated the engines a little though. Performance is a little bit sluggish on this one.

    Yeah, the big jets are very popular, probably as there are fewer of them. Yours does fly like a big jet, very majestic.
