  1. After years of trying, I've made a ornithopter in KSRSS. I've been wanting to build one for so long, but Kerbin and it's planets/moons are just not up for the task. Luckily I discovered the methane rich moon of Titan which contains a very thick atmosphere while having a low gravitational force. This makes Titan a perfect place for ornithopters. My design flies pretty well... however, it's does it very slow. I don't think it there would be any real uses for this type of craft... Propeller planes or drones would be much more efficient. Nevertheless, it was a very cool project to work on. Here is a small video of the craft in the wild.
  2. I MADE AN ORNITHOPTER IN KSRSS! after years of fiddling with the concept, I finally made one fly! It flies like fecal matter, but nevertheless...IT FLIES haha I made a small video of the craft, if anybody is interested.
  3. Pardon me if this is a dumb question. But I've seen pictures floating about the internet where KSRSS and Parallax are combined. Is it possible for a mere mortal like me to install this wonderful mod as well in my KSRSS install?
  4. I did this challenge a while back in VR, without time warp. It was pretty neat! I don't know if my upload checks all the boxes for your particular challenge though. I flew in a straight line to the mun.. but... I think I got into orbit right before I landed though... darn it. Maybe give your challenge real try. here's my videon for whoever is interested
  5. Wait.. you're challenging somebody to do a grand tour with one large srb craft? I don't think it is possible to create a craft like that with just stock parts. Or do you mean several srb launches to every planet and back? This is of course possible. I went to duna and eeloo myself some time ago. getting of eve is a challenge though... have you tried doing the challenge yourself? Links to my SRB mission uploads
  6. Cool. So the craft would drift away from the base. That's pretty wack right? I was playing lone echo yesterday. It's a game where there are several large bases in orbit around the rings of Saturn. Pretty sweet. But I noticed that all the vessels are in a fixed distance of each other, while their altitudes all differ. So I was like... hey that's not how things work in space.. hehe. And now I'm here.. asking these silly questions.
  7. Just a shower thought.. let's say you have a 10 km long base, 'floating' in orbit around kerbin. The base is oriented inward towards the planet, so one end flies at an altitude of say 100 km and the other end at 110 km. I'm asuming that the CoG is in the middle and there is an circulair orbit with the AP/PE at 105 km. Now we release a small part (let's say a mk1 crew pod) at the lower end of the base. We do it ever so gently at 0 kN and 0,0 m/s. What will happen to the mk1 crew pod? Will it follow the base? Staying at 0 m/s relatively velocity to the base? or will it go faster since it's in a lower orbit of 100 km? Will this orbit be also circulair?
  8. Well... I don't know if this count as an entry , because I only have a video containing the highlights of the mission, but I once burnt up 18km/s of delta v in order to get to Duna pretty fast... I believe the burn was completed inside the SOI of Kerbin, but that isn't really shown in the video.. Either way, it's nice challenge and here is a small video of my 'speedrun to Duna'.. (btw..my apologies for the tik tok-ish music)
  9. Very nice challenge! I made a craft land on minmus at ~150 m/s . you can see the landing around 2:40 in the video below. I didn't show any readings so my entry is not valid, but I still like to show you what i've done and (bump this thread a bit).
  10. ah, the KAL exploit. yeah, I've used that one once or twice. so in other words.. you can get to any place with an Ant engine? Very clever!
  11. wow! i just skimmed through your video. but i really want to learn those exploits you're talking about. very impressive
  12. I know @Cunjo Carl did a fantastic speed run a couple of years ago. He defined that visiting all bodies as a main goal of the speed run. I think he did a normal career game. He did in in 8 hours or so. It was a very cool challenge as it forces you to design and fly all vessels in a complete different way!
  13. yeah.. well... there is a long story and a short version.. Short version The deorbiting unit will be flung into space,together with a next fuel shipment. Long version Initially I started recording the video when I finished a working slingshot. I thought I would fling some fuel into space, then dock with the gas station, and then deorbit using another sling... but when I started experimenting with the slingshot in space, I found that deorbiting just cost 50 m/s, while landing (at this altitude) costs 150 m/s! I was like Daaaammnnn.. that makes my design very inefficient! So then I figured that lithobraking was the way to go.. So I had to add a module somewhere. Since I already recorded the ascend part (and also docking the fuel tank onto the sling etc) .. I didn't feel like redoing everything again. So that's why I added a landing module on the gas station. once it got docked, it will stay on the craft indefinitely. I was hoping nobody would find out.. haha I guessed wrong :D
  14. this is absolutely stunning! I have several questions do you always get into an elliptical orbit before you perform your transfer burn to another body? ho do you know where to setup the elliptical orbit? If you get the period wrong it could actually cost you more delta v. and how did you align the relative angle so that you only had to burn prograde? How did you plan the capture maneuver on moho? Do you mind me showing this this on reddit?
  15. Try it yourself the flags are almost indestructible. Only thing limiting is the calculation time step between two frames. if you're going too fast, the collider will miss the flag between two frames and go through the ground and explode when it notices another part is colliding with the ground. this is also the case for fairings, although they are less reliable.
