Wait - The SAS-off button is red? I'm a bit colorblind myself and couldn't notice this till now, even can't see it now... My whole life is a lie

Shouldn't it be possible to get acceleration by differentiating your velocity vector over time?

For me they kept showing up until the desired altitude was outside the SOI, so i was unable to fullfill it. It may need some upper limit, going past the Moon with a sounding rocket does not seem right to me.

I had the same problem a few days ago. The loading screen was stuck there for hours when running the game the first time. In my case it helped to exit the game and just start it again.

Hello! I don't have much experience with kOS, and am basically new to programming, but i'm figuring things out. At the moment, I'm trying to write my own automated plane pilot, using raw controls, but i ran into a problem. I am passing a desired pitch of the craft(pitch above horizon) to my script andd it adjustes the control surfaces to achieve this pitch via a PID loop. The problem with this is the PID tuning. It either works super slowly, but stable, or works faster, but becomes unstable at higher altitudes. When i look at the cooked controls, and see how well and quickly they react, it comes to my mind that there must be a better way:). Could someone pass me an idea how to counter this problem? My script is this(i hope it's ok to post it here): clearscreen. //Attitude Control - Vectors lock fore to ship:facing:vector. lock aft to (-fore). lock up to ship:up:vector. lock rightrot to ship:facing * r(0,90,0). lock right to rightrot:vector. lock left to -1*right. lock top to vcrs(fore,right). lock bottom to -1*top. lock righthor to vcrs(fore,up). lock lefthor to -1*righthor. lock forehor to vcrs(right,up). lock afthor to (-forehor). //Attitude Control - Angles lock absaoa to vang(fore,srfprograde:vector). lock aoa to vang(top,srfprograde:vector)-90. lock sideslip to vang(right,srfprograde:vector)-90. lock pitchangle to vang(fore,forehor)*((90-vang(fore,up))/abs(90-vang(fore,up))). lock rollangle to vang(left,righthor)*((90-vang(top,righthor))/abs(90-vang(top,righthor))). //roll angle, 0 at level flight set wantpitch to pitchangle. set wantroll to 0. set k to 1. on ag3 {set k to k + 0.1. preserve.}. on ag4 {set K to K - 0.1. preserve.}. on ag7 {set wantpitch to wantpitch + 1.

Thanks in advance

First: Great work with this mod collection. You really know what you do. And you are awesome! But one question: If you add b9, will you also add tweakscale nodes to b9 tanks? I know that getting the mass and volume scaling right could be somewhat hard. But back in 0.24.2 i added some nodes myself because the standard b9 parts had to little H2 in them, and that really helped me getting a skylon like ssto up there.
