  1. I think this was an even better run, but the screenshot wasn't perfectly timed: [URL=http://smg.photobucket.com/user/rcgothic/media/2015-11-16_00017_zpsy1qaxcso.jpg.html][IMG]http://img.photobucket.com/albums/v723/rcgothic/2015-11-16_00017_zpsy1qaxcso.jpg[/IMG][/URL] 1009.1 m/s
  2. I started from well after the start of the runway though if we're being that picky.
  3. Smashed it. 1010.5 m/s [URL="http://smg.photobucket.com/user/rcgothic/media/2015-11-16_00004_zpskcsmgbwz.jpg.html"][IMG]http://img.photobucket.com/albums/v723/rcgothic/2015-11-16_00004_zpskcsmgbwz.jpg[/IMG][/URL] [URL="http://smg.photobucket.com/user/rcgothic/media/2015-11-16_00003_zpsrdw98ebt.jpg.html"][IMG]http://img.photobucket.com/albums/v723/rcgothic/2015-11-16_00003_zpsrdw98ebt.jpg[/IMG][/URL] That's a crash into the final light, so it's exactly at the end of the runway.
  4. I managed to get this 1111.3t beast in the air: However I don't think there's any chance I'll be landing it:
  5. Redone! This time with a 'Perfect' as opposed to merely 'Good' landing. On the runway: Ascending rapidly: Angled down for acceleration: Rocket mode activated: Orbit achieved: In orbit: Re-entry (note I spent basically a day in orbit so as to have optimum sun position on approach to KSC): Like Sean I overshot: But that just meant I got to touch down into the sunset: Complete!
  6. First entry of 1.0.5! I've gatecrashed previously using FAR, but I thought I'd use the opportunity of a clean install with the new patch to do things properly. On the runway: Orbit achieved: Preparing for re-entry: Getting hot: Safe return!: For certain definitions of safe. Unfortunately didn't quite stick the landing and hit quicksave instead of screenshot, but that's just a case of re-doing the mission later. I assure you nothing had blown up by the time wheels hit tarmac. My landings still leave a little to be desired.
  7. Uh, what? I think you have some misconceptions. It's technically true that you get lighter as you ascend, but not as much as you think. The acceleration due to gravity at LEO is 7.8m/s2, 80% of that at sea level. TWR increases during a flight primarily because you burn fuel and get lighter, not because you're getting higher! Secondly, TWR is useful as a measure of how much acceleration your ship can pull normalised to multiples of kerbin's (or other reference body's) gravity (at sea level). It doesn't change with altitude. On Kerbin it's basically synonomous with TMR. It's specified as weight
  8. If you're using FAR it confers active disadvantage. Both the greater diameter and the cross sectional area changes add additional drag, in addition to a greater skin drag from additional rocket length. Nobody likes the fairing.
  9. Simplified explanation to aid understanding. I offered three different solutions in ascending order of difficulty and reduced fuel consumption. As always, use of manoeuvre nodes does help a lot.
  10. Burning normal/anti-normal doesn't change apoapsis. However, it DOES change which direction normal/anti-normal is in. If you don't rotate your vessel as you burn you will no longer be burning in a purely normal/anti-normal direction and so will be burning a little bit pro/retrograde, which will change your orbital velocity and therefore altitude of periapsis/apoapsis. Choose one of three solutions: -Accept the change in orbital velocity and compensate with a later burn to adjust apoapsis/periapsis. (Easy) -Rotate your vessel as you burn to stay pointing normal/antinormal. You can dynamically
  11. Alright, time to bust these gates wide open! Any consensus over whether using FAR is easier or harder than stock these days? Take off: Orbit: That's about 400dv remaining. Re-entry: Overshot a bit: Sightseeing: Coming in for landing: Touch down! Not so useful payload: One bored scientist. Several hundred unused units of fuel. Now to upgrade to something actually useful.
  12. Burn at apoapsis to adjust periapsis. Burn at periapsis to adjust apoapsis.
  13. It's not difficult to give a small probe an insane amount of dv. What's the payload?
  14. I did, but I used them for braking on the runway once I was down.
  15. I just successfully completed my first SSTO spaceplane mission and only used stock parts. But I suspect I don't qualify for the K-prize because I have FAR installed?
  16. I'm only going on my recent experience in building my first SSTO spaceplane. At 20km and 1200m/s I started to lose control, with the craft wanting to go into a flat spin and then backflip. It was solved by the addition of forward canards (pitch) and a much larger tailfin positioned further back (Yaw). If that's not your issue, then where are you struggling? Not enough dv? - - - Updated - - - I'm only going on my recent experience in building my first SSTO spaceplane.

  17. A tip is to have both vessels facing Normal/Anti-Normal. That prevents rotation as the craft orbit. Also I don't think re-docking the same vessel undocked counts. I discovered that by trying to dock to a probe launched on the same lifter.
  18. Successful landing! Returned a payload of one passenger and 270 units LF and 300 units Oxidiser. And I flew to orbit with my gear down. Airbrakes on re-entry made all the difference!
  19. I suspect you don't have enough Yaw or Pitch Authority.
  20. Sepratrons are kind of unnecessary. Just spin the rocket up around its central axis before detaching the boosters and they'll be flung away by centrifugal force.
  21. Is "Upgrade your Duna spaceplane to be a Kerbin Spaceplane and refuel in orbit" a valid suggestion?
  22. Thanks guys, all very useful! I'll make sure to double check where all the fuel is and shift it forward before my next re-entry attempt. I suspect the fuselage tasks will be basically empty with the nacelles half-full and I'll need to pump those forward. I may try adding some airbrakes too. It sounds like flaps/spoilers won't be terribly useful for a canard/delta design though as the trailing edges are too far from the COM.
  23. Thanks for the tips. Is there anything to add regarding the use of flaps, spoilers and airbrakes? I.e. how to. What I meant by keeping my periapsis up is generating enough lift such that even though I'm slowing down, periapsis doesn't fall too deep into the atmosphere before I'm properly slowed. I guess I also don't understand why speed and altitude have such a negative effect on stability parameters. Why does Yaw Stability fail? It's not like the nose is getting larger and the tail smaller.
