Mechjeb acent guidenc problem

[Avarax]

Hi, I have a problem that I can not set ascent guidance to work according to the settings.

In the settings I have set to start to rotate at an altitude of 10km and this completely ignores and I do not understand why Can't help me?

Force roll only has two settings, what you want to roll to right after the engines ignite, and what you want to roll to as soon as your gravity turn begins, which occurs at a certain altitude. You can manually set the altitude to be whatever you want, but 10km is too late.

Instead, set the Turn Start Altitude (in the edit ascent profile window) to anything between .1 and 2.0 ideally, then check the Force Roll box and put 0 in the first block and 0 in the second block. Then monitor your ascent and when you get to 10km altitude, type 180 (or whatever you want to roll to) in the second block. 

So if you did exactly that, your rocket should take off from the pad and immediately roll so that the nose will start to pitch “down” as the gravity turn progresses and continue to do so until you change the second block to 180, at which point it will roll over on it’s back and continue the rest of the turn “upside down”.

Hope this helps.

Gravity turn and roll during ascend are two different and unrelated things, roll during ascend makes sense for something like a space shuttle, bit is usually neither required nor useful for normal rockets like the one from your screenshot

I suggest to disable the settings for engine overheat, roll climb, limiting AoA, limiting acceleration, these are usually not required.

That's the most important setting here, yes.

ok and how do I set the orbital turn not to 90 but to the north so that after start I turned north and not 90 degrees

[VoidSquid]

That's the inclination, set it to 0 degrees for going to the east, to 90 degrees to go north.

From Wikipedia https://en.wikipedia.org/wiki/Orbital_inclination 

• An inclination of 0° means the orbiting body has a prograde orbit in the planet's equatorial plane.
• An inclination greater than 0° and less than 90° also describe prograde orbits.
• An inclination of exactly 90° is a polar orbit, in which the spacecraft passes over the north and south poles of the planet.
• An inclination greater than 90° and less than 180° is a retrograde orbit.
• An inclination of exactly 180° is a retrograde equatorial orbit.

Since the question is about a particular mod, your question has been moved to modded support. Good luck.
