Cutthroat Rocketry Challenge

[SanderB]

This is simply a challenge to see what is possible with stock parts and FAR aerodynamics.

The back story is simple, Kerbal rocketry is becoming a more and more crowded business and prices are getting more and more competitive. The extremely hostile aerospace environment demands the lowering of launch costs, and thus the cost of sending fuel to orbit. One of the main aspects in which we can theoretically lower cost with present day technology is in the more fuel efficient launch of fuel to orbit, which we can use to extend our reach into the kerbol system and beyond. It is your goal to improve fuel economy or be left biting the dust. A few bonuses are given for full recovery.

Rules:

KSP 0.25, FAR and Deadly Reentry are mandatory.

No air intakes or solid boosters.

No staging, separation, losing a part due to burning up or aerodynamic stresses, until periapsis >70km.

No modded engines/fuel tanks or any parts that perform better than stock.

No mods that enhance the flight characteristics of your rocket (exception: procedural fairings).

The rocket must have a docking port that has a diameter no less than 1/2 the diameter of the rocket.

The docking port must be usable once in >70km orbit.

Allows mods are (for example) kerbal engineer, MechJeb and KOS script.

Definately not: tweakscale, b9 aerospace, KW rocketry, .

Scoring:

Fuel Fraction (Fuel in 70km orbit / Fuel at takeoff) * 100%

Video entries will be granted a 0.05% bonus on top of their calculated fuel fraction.

Video entries which show the rocket landed/splashed-down within 50km of KSC (after reaching orbit) are granted another 0.05% bonus and an asterisk.

Video entries which show the rocket landing on the launchpad (fully on the flat part of the launchpad) receive another 0.15% bonus and a 2nd asterisk in the hi-score list.

The last two bonuses for recovering your rocket are only valid if no part of the rocket is lost during descent.

Entry format #1: Screenshot at takeoff and in final orbit (both showing the ship, navball and resource tab). More screenshots are welcome.

Alternatively post a video on YT or another public video hosting website (without any annoying adds).

May the best rocket & pilot win!
