largest 4 engined plane

[toxictalon74]

it must be able to take off, fly and land

the following mods are allowed

mechjeb

damned aerospace

damned robotics

ALL OTHER MODS ARE BANNED

rules-

1-no exploiting bugs or glitchs

2-the plane must have 4 engines

3-i need a picture of it taking off one of it flying and one of it landing for it to count

4-jets only and things from the mods

5-no editing files in the game for more thrust,less mass,less drag,etc

bonus points are awarded if your plane can land on water and take off again and if it can reach 500M/S+ in speed

Largest by size or by weight?

Does it need to land on wheels or are other methods of non-destructive landings acceptable?

[toxictalon74]

all methods of landing are acceptable accept crashing i will update the description now

You need to disallow mods. Otherwise I could just edit the engines to have 10x the thrust and totally ruin the point of the challenge.

Also, RCS should be exluded for similar reasons.

[toxictalon74]

well i put a limit on the mods but

you would need massive amounts of RCS to move a large plane and remember only 4 engines that includes RCS meaning it wont get off the ground or even move in the first place

I have a lovely large 4-engine plane that can't land intact, but is survivable.

50 tons before liftoff. Stock parts.

It won't come down slow enough to touch its gear down safely?

Nope. It has to have engines going to sustain level flight, around 100m/s minimum. Even so it's too delicate to land even at normal speeds; it'll sometimes go to pieces just from its own thrust at launch, if one of the landing gears glitches and gets stuck.

44.8 tons, landed with 44.4 tons

(does it have to land with full-ish tanks?)

[GoodGuy]

How is that a 4-engine plane? Aerospikes are engines too, ya know?

[VincentLaw]

Here is my entry (fully stock). I went with a biplane for the obvious reason of structural integrity since I wanted a long wingspan. The launch clamps are just to keep the wheels from sticking at engine start. I have no trouble designing larger airplanes, but any more parts than this and my computer gets angry. I think using fuel before landing should still count because in real life airplanes often take off with more than their max landing weight, but I do think it would be possible to land this plane with full tanks too, just difficult.

I didn't really push the limits too far, but here are some stats. The mass is calculated and the others are estimates.

Takeoff mass: 119.29 units

Max Ferry Range: +1200 km

Flight Ceiling: +12000 m

Max Speed: +300 m/s

So I was thinking about what to do with my new giant airplane and I decided on an expedition to the south pole.

(technically that's landing on water)

Well, I just tried this challenge, and completely filled up my RAM. I wish my actual RAM would arrive.
