Build a Specific Kerbal-X replacement [Challenge]

[Sirine]

Well, this is base on score-system.

[B]Simple Description: [/B]Build a Kerbal-X replacement, with the following requirement:-
[B]Upper Stage[/B]
1) 30 tons 
2) 3000 Delta-v 
3) Torque value 30
4) Thrust value 120.

[B]Full Stage[/B]
1) Part Count 150.
2) 3 crews.
3) Total Torque value 0.1 per total Mass. 
(If your total Craft Mass is 150 tons, and Total Torque value is 15, means 15/150 = 0.1)

[B]Landing Stage[/B]
1) Full upper stage craft landing.
2) With 6m/s Landing Velocity.(Land on Kerbin)

Please carefully read and understand the score-system before you participate.

So, you may wonder, how is that 'score-system' works anyway? Well, refer to below image.

Torque = Torque/mass, Thrust=Thrust/mass,

Always refer to "Desired value". The more you match the value, the more score you get. So, 'more' doesn't means good. Design to be specific, that is the goal.

Example: If you manage to get torque value of 1, with 30 tons mass, 4 thrust, and 3000 Delta-v, these will give you full 40 marks.

Ok, let's check on the Original Stock Craft: "Kerbal X".

Confuse? Check on the 'Crew', desired value is 3.

Means if you bring extra or less crew, you will get less point.

Same apply to all the 'desired' fields.

*Part Count: This is the total part count for a full craft.

*Torque: This is the [Total Torque Value/Total Mass] of a full craft.

Example here for the Kerbal X.

Total Torque Value=15

Total Craft Mass =131.67

15/131.67=0.11392116655274550011392116655275 (9 marks)

I'll have to keep track of this one. I missed all but the last one with the long distance plane... and me and planes don't mix well
