This is a bug, they’re supposed to be there. The game as it is now is nowhere near where they want it to be, that’s why they released in early acces. Let’s just hope the patches fix a lot of the bugs and incomplete features when they start being released in a few weeks

[@Draxi_1]

@@thespacepeacock Exactly. You either pay 50 now or 50 after but you still get all the features. Tbh it's nice they did an early access release to drive the development by community feedback and not just to cover up the bugs. They definitely have functioning QA department and in the game's current state there is no chance they would've made a full release and not expect a huge backlash. What's funny is people paying the full price and not even caring to look what's in the early access game. One of the first things you see on the store is their roadmap and people giving bad reviews because there is no science or multiplayer is just wrong. At least these reviews get reset when it fully comes out.

Doing some quick math. During the segment of the trans-Jool injection lasting from the first frame of 6:53 to the first frame of 6:59, the craft's speed increased by 1764 m/s while the listed Dv dropped by 17 m/s. This means that each m/s of listed Dv is worth about 103.8 m/s of real Dv, and so at the time the vessel left Kerbin's atmosphere, it's true Dv was 1445x103.8 = almost exactly 150 km/s. Side-note, during the aforementioned burn the acceleration was 294 m/s^2, or about 30 g.

[@hendrikpoggenpoel4508]

One quick tip. When you are in Time Warp, you can use the / key to automatically drop out of Time Warp and go back to x1 speed. I don't know if this feature was in KSP1 but I don't remember it being there.

To limit the wings flapping, i found that reducing the depth of the control surfaces helps. I think that it's repeatedly overshooting the target, so making is thiner allows smoother control.

[@alexanderkuhn2298]

I've had better results doing this as well, also designing planes that don't require SAS or just not using it at all. The issue is exactly what you say, it is overshooting, then oscillating too hard as it tries to correct. The code that would do this autocorrection by overshooting then undershooting until its stable is called a PID controller which controls the hysteresis or in other words the oscillation you see there. It can easily be fixed with some fine tuning and some other considerations. They need to lower or fine tune the gains on these controllers, meaning the initial correction of pitch would either be a lower angle, or the flap movement would have to be slower and more methodical as to not change the pitch so rapidly. The rapid pitch change is both overshooting and causing drag related effects with the body and wings that compounds the issue. The other thing they might need to do is modify the drag characteristics of the procedural flaps, especially since the large ones seem to have a wild effect on them. Maybe they can factor in the surface area of the flaps into these PID controller calculations in the future, make things more stable. Sorry, engineers are boring I know, but the fact that I can see the solution in my head and its not there yet bothers me. I have been looking around the config files in the game to see if I can change it myself and maybe put out that info for others to try as well.

[@aidenmclaughlin1076]

I found using 'control surface' wings instead of regular 'wings' or 'stabilizer' in the rear helps with pitching issue. Seems the size of the control surface actually affects it.

It seems like the part detaches from the craft, but is still considered part of the craft. That causes the camera glitch because the camera focuses on the center of your vehicle. They really need to fix this and the VAB bug.

[@clintonhawkins8666]

Just create a maneuver node that results in a collision with the body, then adjust it slowly until it just barely doesn't result in a collision. Then you are going to have a fairly close encounter.

Something that helped me with the flappiness of the wings was lowering the control authority a bit. It made my plane turn *very* slowly but I could actually control where I wanted it to go

[@MeltEmber]

As for who the first discoverer is, that's a very difficult question. Stratzenblitz discovered the missing obstructions during a stream and also noticed a potentially drag-reducing behavior with docking ports (which turned out to not be the case, it's simply the fact that it occupied a node - always occupy all your nodes!), so everyone immediately started experimenting with engine obstructions. I focused on nuclear and ion engines, without success. I assume that this rapier kraken drive is the result of that and that multiple people might have discovered it at the same time.

I would love to see like a modular space shuttle heat tile system for the wings and all of the space plane parts.

You should do a recreation of the flights of The Martian, where the space station comes back to Kerbin accelerating, then gravity assists while docking, then shoots back to Duna and intercepts an escape pod from Duna, all while not in orbit because there is not enough fuel to enter Dunas orbit.

[@travistolbert2647]

One thing that the SAS system is trying to mimic is a fly by wire flight control system. A big hurtle with Fly by Wire systems is programing the amount of authority they have at a given time and situation, when to apply corrections, by how much, etc..... One thing I believe is happening here is the SAS is using 'too much' authority, doesn't know how much a given control movement will have on the craft, and the control surfaces that are too large. Your SAS system is correcting, then over correcting the correction too much resulting in the flapping control surfaces.

[@amanofnoreputation2164]

[Tylo is the hardest planetoid to land on and return from.] I should perhaps qualify this statement: Eve is the hardest body to return to orbit from after a landing because of it's high gravity and thick atmosphere, but this is more of a design problem than a piloting problem. Tylo is much easier to meet the delta V budget for, but the actual process of decelerating down to the surface is extremely challenging because you have the same gravity as Kerbin but no atmosphere to slow you down. I should know because I've attempted it many times and not succeeded. Eve is dead easy to land on because all you have to do is aerobrake.
