Your answer lies within.

I get this is a piloting challenge first (didn't you notice my sleek flight profile?) I totally understand it can be considered anywhere between a 'tweak' to straight up 'removing parts'. However, my arugment would be that the challenge is for least LF used to get to orbit, and OP did give some tweaking leeway; which, IMO, removing the unused oxidizer to reach said orbit is 'tweaking' and not re-design of the vessel (technically, I'm not removing parts as part count does not change). Up to OP in the end, just thought I'd bring a new angle to the challenge.

yeah, wasn't sure it would, and was leaning toward probably not; but its worth a shot. thanks for the clever points

Not sure if this will count, but I haven't seen anyone try this yet. Since this challenge is most left over LF in orbit I maximized my payload as such. There is a fair amount of oxidizer left over from a fully fuel laden vessel. However, if you take all the oxidizer out of the last stage, you can get to the orbit on the swivel alone, top tank full of LF, with some to spare. Here's my possibly legit submission. Manual launch, 198 LF remaining.

I was just about to post this too. from 90th to 17th. WOOT!

bless you.

I mean like radially mounted engines angling so far as to torch the tank they are attached to.

I wonder if that's enough range of motion that a funkily designed ship could gimbal far enough to blow itself up.

I use them all the time. In fact, almost never launch without them. Then again, I usually do pretty aggressive launches, turning early and pushing the limits of speed and heat. I'd really like to see an inter-stage fairing, it would really open up the building design options.

Oh my, this. Whereas I don't really care how the dev note content is presented (as long as it is informative), the biggest turn off was the grammar and punctuation. How wretched. If this were free of errors I would have taken the change in stride, but this is a literary train wreck. Please try to proofread before publishing. This is your image, make it a good one. Thanks for clearing up the threads/cores and explaining some PhysX stuff for folks. Performance gains are speculative and hardware specific, but hopefully it'll be awesome. I really enjoy reading about the more under the hood bits and welcome more tech-y information. Thanks to you all for creating an incredible game. ~madchris

OK, after cantab pointed out some deficiencies in the rule set, they have since been revised (thanks!). I hope this makes it a little more flexible and flavorful of a challenge. Let's see where this goes, and if any further refinement of rules is needed I'm open to suggestion. Thanks for the input, now let's get this party started!

I see. As this is meant to be simple as possible to start, I'll edit the wording to be LF/LOX only for now. Im out of town for the day but may expand this to include other fuels in the future. Thanks for your input.

Meh. see Rule #2. Once you start allowing mods people's physics get altered and consistency (and fairness) gets out of whack. I'd like to avoid that stuff all together.

Fuel Sipper Challenge I've been wanting to come up with my own challenge for a while and after doing the Flight School Challenge and seeing the efficiencies of participants vary, I wondered how little fuel one could send a kerbal into orbit with. I'm a minimalist and all about efficiency, so this was right up my alley; hence, this challenge was born. Your Mission: Design a vehicle to get a single kerbal to a 100km x 100km orbit while consuming the least amount of fuel (in kgs) to do so. Your Kerbal does not have to return. This is an exercise in design efficiency and piloting prowess. Rules: 1. Stock parts, normal difficulty settings 2. No gameplay/physics altering mods (visual and informational mods ok) 3. No exploits or 'cheaty' (Wheaton-y) stuff, no clipping of functional parts (fuel tanks, engines) 4. Must have 1 Kerbal on board. 5. Must have at least 1 screenshot of vehicle on runway/launch pad with the resource tab open, and 1 screenshot showing the craft in a 100kmx100km orbit with the resource tab open. 7. Once in orbit, subtract any remaining fuel from your starting amount to get the total consumed for each fuel type. (be sure to subtract the exact amount remaining, I have a feeling tenths and hundredths of fuel will make a difference between scores.) 8. UPDATE: You can use any propellant you like. Your score is the total mass of all propellant spent to reach orbit. Multiply total fuel spent by it's appropriate mass.

This thread makes me so giddy. You guys have done awesome work here. Val, your design is the shiz, over the top. 4k dV is ridiculous for <15 ton SSTO. Way to go, pushing the limits, maximizing. I applaud you! So, thanks for being kick-ass kerbonauts.
