  1. Yes, works again. Altough it works when i click "my account", it does not when i click on my name. LOL.
  2. Well, i have different problem. I enter: https://kerbalspaceprogram.com/kspstore/ I log in using my credentials. I see "My Account" button. But when i click on it i'm just redirected to: https://kerbalspaceprogram.com/en/ . I cannot download my game :(((
  3. Go to settings and set time to Earth days. Kerbin day = 6 hours, and its default setting in new version.

  5. No documentation in wiki about node (broken link in manual). Can orbit object return apoapsis/periapsis ETA? What do you think about periapsis/apoapsis returning object, not value, like I described here: https://github.com/Nivekk/KOS/pull/277 ?
  6. Yes, but lets forget about hybrid and about restarting engine during driving - both are rather impossible for most drivers. But if you do not shut down your engine during "glide" its better not to be in "neutral". When you are in neutral engine uses fuel to spin at idle RPM (around 900 usually). But if you are not in neutral while driving and not pressing gas, you are doing "engine breaking", which means that engine is not using fuel at all, because engine is propelled by wheels. You are loosing speed faster than in neutral (engine breakes), but you do not use fuel at all. Most opinions i've read says that it is more fuel efficient to use "engine breaking" and not use fuel at all, than glide longer but with engine on idle.
  7. Also, about going downhill. If you drop red ball it will reach faster finish line on green(longer) track than on black track.
  8. First about "sweet spot speed" - it depends on engine RPM AND gear. If engine is most efficient at 2000 RPM then it will be different speed on 1-st gear and on 6-th gear. And of course aerodynamics. (you will for sure be more efficient at 2-gear than 1-gear, because air resistance is still small, but you can be more efficient at 5-th gear than 6-th, because even you are driving faster with the same RPM, you need more fuel to keep that RPM). I also heard that most efficent for car engine is not too drive with constant speed. Most efficient way (used in contest for low fuel usage) is to accelerate hard then let car slow down, because engine is more efficient while accelerating, and doesn't use fuel at all while decelerating (engine breaking). Its not health for engine, but its most fuel efficient. Just like ecodriving - it says "accelerate hard, but change gear to higher as fast as you can" - it will lower fuel consumption, but will wear your engine faster. And now back to the hill problem - for sure you can't drive too slow. Its just like rocket - you need to use part of your engine force to fight gravity. Rocket with TWR 1.01 will not be efficient. Also driving car 1 km/h uphill while pushing pedal so much that on flat you would go 31km/h means that you are wasting 30km/h way too long. You can pretty easly compute what additional force works on your car while driving uphill, you just need to know how steep hill is, and use sin function. Normally this force is neutral because works vertically and you go horizontally. But while going uphill it is like rocket fighting gravity. Rocket stops fighting when it will reach orbit. Car will stop fighting gravity when it will reach top of the hill. Does anybody here was ever driving uphill on bike (without gears)? Does going slow make it easier? As far as I remember its best to start fast and go up as fast as you can, not go slowly...
  9. Yeah, time travel - i've forgot about that one. Always suscpicious to that too. This "lol, we changed future, now x person are dead, and y are alive. Lets reverse that, because 'our' version we like more".
  10. So, there are few ideas in SF books or movies which seems pretty stupid to me and i don't like them: 1. People teleportation (like in Star Trek). So, computer scans you, in the process your body is destroyed. Then information about your body is put in computer buffer (sometimes due to glitch for hours). Then computer rebuilds your body in other place using stored information. For me its just death of person in one place and creating copy in other. But nobody is disturbed by this. 2. Infinite number of parallel worlds with copy of human population. Like in SG-1 in few episodes. Sometimes one world helps another world, leaving 99,9999% others to its doom. Or not, because something is slightlly different in those. I don't like that - you would want to have your world somehow unique, and if there is device to travel between worlds you could easly transport army, goods between worlds. Something like in Terry Pratchetss "Long Earth" - there are infinite number of worlds, but humanity is unique. So i accept parallel worlds as long there are no human copy on other worlds, or when parallel worlds number is not infinite (like in Fringe, there were 2 Earths, not more). Do you have others (not "no sound in space", but those somehow scientific) ?
  11. Nope. In your example everything works as it should. Look at your staging. First stage is to ditch fuel tanks, second stage is fire engine with central tank. I think that this is not bug in KE, its just TurboJet ISP wchich is changing, so KE estimations are not correct.
  12. Its all by the rules, so you should probably alter rules. Solutions: a) Ban TurboJet engines Provide .craft so it will become purely kOS contest c) Use other method of counting used delta-V. Once MechJeb had "used delta-V" stat, I don't know if it has one now.
  13. Really nice plane. You had spaceplane autoland program? Can you share?
