I’m nearing 1500 points so I’m dedicating this plane to this milestone.

This is not mobile friendly

FYI it has 537 parts. Some higher end tablets can handle it.

The Ultimate twin airlifter

This plane is a military and civilian twin-engined airlifter with a pair of JE250 engines, which are larger and more efficient jet engines developed from the JE210. The landing gear is unique in that there is no nose gear in the gear configuration. The fuselage is 7.5m wide minus the ramp, which allows for more capacity and flexibility than its quad jet predecessors, the C-5 and the C-17. The two engines produce 165,200 lbf (735 kN) of thrust each at sea level, making it 23% more powerful than the GE9X engine that powers the Boeing 777X. This allows the C250 to have excellent STOL capability, being able to take off and land using about half of Bandit Airport's runway length even with 135 metric tons of payload.


The plane features a three-deck configuration in the nose, with the middle deck as the flight deck and crew quarters and cargo storage in the other two. Behind the main cargo hold and the massive cargo ramp, there is an auxiliary hold (which is smaller and higher to allow for a large cargo door and to prevent tailstrike) which can store smaller and lighter cargo or be fitted with seats to transport troops in airline-level comfort.


The JE250 turbofan engines feature a three-spool layout to produce more thrust with smaller size and less drag. They have four doors on the side to allow for reverse thrust. The engines also have flexible blades to increase pitch at higher speeds and rpm.


Controls:

AG1 and 2 - start respective engines 1 and 2
AG3 + Brake: reverse
AG4: arm spoilers
AG5: cargo ramp
AG6: Strobes
AG7: Landing lights
AG8: Nav + Beacon
VTOL down for flaps
Trim for trim (duh)


Checklists:

Engine Start:
AG5 off
AG8 on
AG2 on
AG1 on

Before takeoff:
Set flaps - VTOL down
AG6 on
AG7 on

Before landing:
VTOL (flaps) down full
AG7 on
AG3 and 4 on

After landing:
AG 3,4,7 off
VTOL (flaps) set 0
When clear of runway, AG6 off

Parking:
All AGs off


Takeoff & landing instructions:

For takeoff, after doing the before takeoff checklist, apply takeoff thrust (70% recommended) and gently pull back on the stick after reaching 130kt.
For landing, do the checklist, and fly final at 125kt. After touchdown, apply brakes as necessary.


Enjoy!

    @KnightOfRen The mods are not listening and still did not make this a successor. I'm sorry. I'll try to get them to help now XD

    @KnightOfRen lol I am entering this in your challenge. I hope this is up to your standard, since this is my most part count build. Yet even with this part count, there is basically no aesthetic detail here. I mean, I think this is one of my builds that didn't gain enough recognition for what it's worth. Also, you might be aware that I use custom thumbnails now. I made this on iOS before 1.10, and custom thumbnails were impossible on mobile before then because of lack of mod support. I hope you will wait a bit before you grade this thing because I will add to the description soon with some more detail and a photo gallery.


    As a final note, I made this before 1.5k. Even though it wasn't that long ago, I did have lower standards back then.
    P.S. Since the competition is not that great, I hope I win. I think following will serve me well and I desperately need another follower. I don't really care about the 10 upvotes at this point since it only gets me 150 points. I might want it more if it gave me 1500 XD
    P.P.S. Ignore the lack of part smoothing. I made 90% of this plane even before the 1.10 beta released. I don't think it should count as a part of design because it is not a trick you use to make the plane look smooth. You just change it with a click of a button.
