Oh yeah, the second one is what i am experiencing. I am getting better at it and have now worked around it, but it's definately not helping either

Oh, by the way, don't wanna create a different topic for it, i try to use the mentioned formula for an efficient ascend from Kerbin, so, trying to ai for 45° at ~ 10km height and then set to prograde and keep the AP at 50 seconds away. Doing that, my current AP is around 50k, so i think i am too shallow. My first stage has a TWR of 1.68 with 850 dV and the second stage kicks in at around 5k with 1.38 TWR and 3.2 kdV. If i let SAS Prograde do the gravity turn, i end up at 25000 meter, if i do it manually, i get to 50k, so i think the drag is too high on the vehicule? Would a good or efficient launcher go to 80k with that kind of ascend procedure?

Hey, thanks for taking your time to answer The relative speed being all over the place happens as soon as you turn SAS on to align towards the target. So, i undock, i set the target to the other docking ring, i switch to relative velocity and to docking mode, everyhting is fine and stable. As soon as i turn my vessel towards target, the speed starts to quickly cycle from, +2 to what the actual relative velocity is to -2 of that and then rinse repeat forever. I did it at 100m, it stayed that way until 1100m . Then i started to burn towards it and the speed alternated between 5 and 20 m/s, and everyhting in between. I knew i was closing in, because the distance got smaller, but apart from that, no clue. When i got closer, the relative speed went to 3-6 m/s, with no change in velocity. But then it was pretty quickly back up again. All this is done just with SAS corrections and main thrust towards target and then retrograde to get closer. At the end, i was at 12 meter disctance and had killed most of my velocity towards the target and now the velocity at the navbal was switching between 0 and ~1 m/s and the retrograte marker on the navball is moving around like it has a spasm, and as a consequence the active SAS is moving the shhip all the time to keep retrograde. If i switch to stability of docking mode for SAS, the vessel keeps twitching, only when it is really close, and you actually managed to kill almost alle of relative velocity, both the orietation of the vessel udner SAS and the display of relative speed calms down and remains stable enough to do precision manoevers. This is with a MK1 landing craft with no extra SAS modules and 4 symmetrical attached rv-105 rcs thrusters.

So, i am trying to create a mun orbiter stage where i can unduck the lander, fly to the Mun, come back, rendezvous and fly back to Kerbin. To do that, i am first practising my docking and how to effectively rendezvous at all. And the game is different from the tutorial videos i have seen. I am undocking switching control to the lander, wait till i am 100 meters away and then try to dock back up. What i understand i need to do to succeed is this: 1) set the docking clamp as a a target. 2) switch to docking mode. 3. Switch to target mode for velocity 4.) point towards target and burn a little. 5.) once i am close, burn retrograde to kill off velocity 6.) use rcs to do the last steps by going normal and then do just simpy x y z axis manoevery with rcs until i dock. The problem however starts when i am doing step 4 and 5. even without rcs on and sas only on stabilize the target speed and direction of it's speed is wobbling, so the direction is circling around as if one of the capsules was rolling somehow, but both are stable with sas. also, apparently the relative speed is also varying between 1.5 and 4. So the game is clearly having a stroke, but at some point it will stabilize. Trying to do any of that stuff with RCS seems like the worst idea ever, because RCS seems to not be able at all to keep anything stable. When it's on together with SAS, the vehicle will always start to become unstable in relation to the target. Second, going normal does not do what has been advertised. It doesn't put the two vessels in parallel mode. i have a very very small relative velocity but i am gliding next to the other vessel and there is no easy way to set me up. prograde is just spinning me for some reason with the prograde indicator always being really far away from the nose, retrograde is wobbling again normal puts me, it could be orthagonal, i would say it's not, but i can's really see a real direction as well, anti normal is the opposite direction, radial is the center of the red half and the degrees are just floating as if i was spinning and anti radial is the opposite. And target of course puts me directly at the target. What i probably could to is cheat, switch to the other vessel, and set the target there as well to point at it, but there has to be a real way to do it. Why does normal not work for me?
