  1. I've never done a grand tour so I thought that I try to do one. Landing the same ship on all planets with only stock parts and without isru is actually pretty hard. Here is a teaser:
  2. I love the eve landing with the catching the lander and docking the large ships while suborbital!
  3. i tried to get back down but 1.0 Eva fuel was not enough... I could retry the launch to get a lower PE
  4. Getting to orbit is not that hard: Geting down however that is a-bit tricky.. It would probably work to do an eva landing if you jump out of the pod after the worst of the reentry heat has passed.
  5. Another tip is to use spaceY decuplers, they have built in separatrons.
  6. The engines need to gimball less if the they are further from the CoM. so they can handle more shift in CoM. Moving the fueltank (and hence CoM) forward also helps. If the main engines are tilted more then they can gimbal they can't be used after separation of the fuel tank. But they should not be, only the vacuum engines should be used after tanks separation. If twr is the problem try scaling up those vector engines.
  7. Nice looking shuttle. One tip: it is better to have the shuttle main engines further back, as that allows for them to be less tilted. What payload capacity does that shuttle have to LKO?
  8. Yes i did the launch directly into the inclined orbit. Here is my next entry:
  9. I did it, I managed a proper landing with an asteroid: STS9 second attempt album
  10. 98% sure. I have been trying to improve stability while flying with the asteroid. To be able to more like "land" and less like "controlled crash". And I do not want to modify the shuttle to mush. The next plan is to attach a RCS system to the asteroid.
  11. Wow... that sounds really bad. I have after several attempts managed to land a class D astroid: STS9 Album
  12. The mk4 form factor is nice when building space stations out of the USI Kolonization parts. The shuttle can comfortably fit the size 3 "Tundra" parts, or even two 2,5m stacks side by side. I built this station in four launches: STS5-8 album
  13. When empty is is quite close. So close that I have been trying to move the CoL further back to gain increased stability. The Mk4 fuselage parts generate quite a bit of lift and CoM is very far back when empty. The size3 vecor is like 70t. Not really sure how tweakscale scales it but i think it keeps twr constant. And as the stock vector is like 5 times more powerful than other size 1 engines, it retains some of that when scaled up, It has more thrust (and mass) than 4 mammoths. I don't use FAR. And I try limiting the mods to ones that are reasonably stock balanced.
