  1. He is "safely" living out his "retirement" from the astronaut corps and is returning to his roots as a test pilot. I use him for test flights of my spaceplanes but I tend to use a different kerbal for full missions.
  2. This is one of the most impressive missions I've seen on this forum. I wanted to do something like this, but I didn't think I'd have the stamina to pull off all the launches. Good job! edit: Couldn't you bring up more engineers to help Bill? If I remember correctly, multiple kerbals can work together to move heavier parts
  3. Some people don't want to buy the DLCs (like me for example). Anyway, here's my submission for a long range SSTO. I'm not sure how truly "beginner" level it is, but it's very capable in the right hands. https://drive.google.com/file/d/1AyCK1NlSaDLKO-1SKx2OEZ5JYnXQGj2T/view?usp=sharing This craft can reach orbit of Kerbin and then land at the KSC eight times in a row without refueling. If you want to go farther, it can land on Laythe or Eeloo and go back to KSC, three times in a row. In other words, it has a lot of range. The suggested ascent profile is as follows: -Use the entire runway to accelerate -At the end of the runway, pitch up to 5 degrees to maintain altitude -Accelerate at sea level until 400 m/s, pitching down gradually to stay at sea level -Lock prograde until nose is pointing up 15 degrees and stay at 15 degrees pitch until 10 km -At 10 km, pitch down to 10 degrees, and keep gradually pitching down. You should be pointing horizontal at about 16 or 17 km. -Accelerate on Rapier power until 1650-1670 m/s and turn on the Nerv; lock prograde again. You should be at about 21 or 22 km at this point. -Cut engines once apoapsis breaks 70 km (or however long you want) and coast to apoapsis to circularize
  4. this Dres challenge looks really fun - I'll try to do it for as low cost as possible edit: actually I want to make it look cool, not just be low cost
  5. Magic wing rapier+nerv ssto. cheaty but technically fits the bill
  6. @zolotiyeruki are my speed record and range record runs acceptable?
  7. Yes, that's correct Landing gear stability doesn't matter since I take off completely flat on the runway and land on the water
  8. Well, I'm usually able to balance both even with engines at the aft. I place the fairing and engines first, then balance fuel tanks around that, put wings at COM, then put the payload at COM. The result is a stable plane at all points in the flight. The problem here was that my initial plane had too much fuel in orbit, so I took off some fuel tanks and added them to the payload, which shifted dry COM too far backward. It was surprisingly easy to fly it backward. The one problem was that it had no yaw stability because the vertical tailplane was now in the "front" of the craft. I sidestepped this problem entirely by flying upside down and backward, and splashing down in the ocean. That way I can still benefit from wing incidence.
  9. For the landing gear, they're autostrutted by default so I just imagine some struts connecting them to the hull. I could just use bigger landing gear with a negligible penalty to fuel usage - I don't really think that matters. Or I could move the landing gear a bit upward and inward, to the same effect. Essentially this is just an aesthetic thing. The payload deployment could easily be done by deploying the fairing and detaching the payload, and the craft would still be just as reusable, but I thought it looked better to do it this way. In my opinion it's no different from a cargo bay.
  10. After realizing that it's possible to fit two Rapiers and two Nervs into a 1.25m fairing without clipping anything, I decided to give the Purist Single Stage category a shot. 60.684 tons launch mass, 37.240 tons payload mass. Payload fraction is 0.614
  11. I think 4 degrees is the best for hypersonic lift/drag ratios. I stuck with 5 degrees however, and simply increased the wing loading. Leaves a bit of room to squeeze out further range from the craft if desired. Is 30 laps possible? Well, the craft went a good deal further than 25 laps. Initial ascent Laps 1-10 After 10 laps, the estimated range of the craft is 22 laps, but I know that it can probably do 25. At the very least it'll easily beat the previous record. Laps 11-20 Estimated range is 6 laps, but a seventh is possible because this craft has quite good glide performance. Laps 21-27 27 laps around Kerbin * 600 km Kerbin radius * 2pi = 102,000 kilometers range.

  12. Impressive for such a small rocket! Also, welcome to the forums.
  13. First lap is complete. I have 84.4% of my initial fuel as compared to 83.6% in my previous run, but I believe I was less efficient on the ascent this time. Assuming equal ascents, I am using fuel 19% more efficiently but I have 12% less fuel, for a 5% increase in overall range. That translates to a range of about 24.7 laps, and I believe that this craft can glide to a 25th lap. I guess we'll see tomorrow.
  14. That's fine - I have some ideas to get even more range anyway, and this is the perfect opportunity to try them out.
