    Does not seem to be working with .90 properly.. The Smart A.S.S. is very unstable. Does neither work in Orbit nor in Atmosphere.. (Yeah, newest Mechjeb installed) It just does not hold any Craft in position.

  • #134

    Getting an incompatible mod error on startup. Running version .25. Also saying that the files are in the wrong place when they are put into the gameplay folder. Anyone else have this problem?

  • #135

    Are you sure you're using the version of MechJeb that's for .25? The page is incorrect, the latest verson avaliable is actually for .90.

  • #133

    Having problems with the maneuver planner, it just doesn't come up. Also, the ascent autopilot won't circularize the burn...

  • #132

    has this been updated for beta .90 yet?

  • #131

    speaking of the serious update to .90 now all mods will need to update massively

    Kindof Works in 0.90

    Works - almost.

    Some of my previous vehicles are now experiencing trouble launching using the Ascent Guidance. I recovered them, well, most of them, half-way through the flight by switching to manual control but it looks like after 10,000 meters when it tries to do the gravity turns it doesn't quite know what it's doing. It either doesn't move or flips the launch vehicle too far over. This could be an easy issue to fix just not sure what is causing it. Perhaps Squad changed some of the aerodynamics.


    Looks like the update fixed the issue. MechJeb is working perfect with 0.90 now. I was getting tired of having to manual control it all the way, haha.

    It ties in wqith the ability of the tracking center, after i had it it fully upgraded mj had no problems, im guessing it needs the upgraded telemtry to work proerlly, so if you not steam rolling on easy you should have no problems.

  • #130

    Thanks, I'll have to try that.

  • #127

    If I'm correct, Kerbin is bigger now?

  • #128

    Actually, it is the same size. They just added in some new biomes.

  • #126

    I am seeing the same thing. as described above. The update caught me off guard. 

    Any idea when we will see updates on the mechjeb side?

  • #124

    Seems to be working fine for me in 0.90 even ties in nicely with the space centers upgrades at the tracking center.

  • #119

    I can't seem to get this to work.  There was a trick of editing the part.cfg file to get all modules at the start of career.  It worked for all previous KSP versions, but now I get nothing.  Did KSP 0.25 put a stop to this?  I really need to know.

  • #120

    I have seen videos with MechJeb working in 0.25
