The version of IFS included with M2X is only the core plugin, not the full version

FWIW, the metadata on CKAN has M2X depending on "Interstellar Fuel Switch", rather than "Interstellar Fuel Switch Core" - so when installed via CKAN it will pull in the full version of IFS, complete with parts and "complementary" patches.

[SuicidalInsanity]

I've edited the Mk2Expansion netKAN, so IFS issues stemming from CKAN installs should be fixed as soon as the Pull Request goes through.

Any chance of doing the same for M3X?

[SuicidalInsanity]

M3X Netkan has been similarly updated..

Question about the Hyperblast scramjet - how do you keep it from overheating? I get my craft up to speed, the X-43 activates, then immediately turns off due to overheating. I've tried spamming it with radiators, using precoolers, and mounting it away from other hot parts. No dice.

Any ideas? Thanks!

[SuicidalInsanity]

@doggonemess: Shutdown due to overheat is a new one - normally engines simply explode. Are you running any mods that add engine heat mechanics?  Best guess is there's some sort of config weirdness going on between it and the scramjet.

[Squishydoo]

just asking, whats the best way to place all the folders in gamedata?

just put the gamedata folder in or all the ones inside it?

[SuicidalInsanity]

Either way works. If you're moving the Gamedata folder from the Mk2expansion.zip, place that in the main KSP directory; if you've opened up the GameData directory in the zip, then move the files inside - Mk2expansion, CommunityResourcePack, and InterstellarFuelswitch and the ModuleManager.dll to inside your KSP/Gamedata folder. The Ships file in the .zip is optional, and that goes in the main KSP directory. The extras file in the .zip is also optional; open the file structure until you get to the two .cfgs, and choose one and place it in the GameData/Mk2Expansion/Patches directory.

I think the interior attachment nodes of the M2X_Servicebay are missing when it's in structural mode.

[entropy--]

Also a question: With the Fuselage Junction parts in place, I've started making a space station "template" that can be lifted up in one go and even flowed around atmospheric planets by a tug-plane attachment.

The one thing that seems to be missing is an Mk2 form factor station "tube", that is much lighter than the crewed parts, but is passable and works well with the junction parts. Are there any plans for such a part?

"Update 13/25/2016". Last year felt shorter than 13 month...

Ok, I'm here to report a issue: All the chine parts seem to be rotated 90 degree. Their lift is toward side instead of up. Looks like this:

(Took me a while to figure out how to post image)

When the stock wings works like this:

Shouldn't the model be rotated 90 degree and the whole thing works like this?

Edited February 13, 2017 by Tony422
Maybe I should say "the physics of the chines are 90 degree different to their model". I don't know how to describe this situation...

[Supercheese]

I've also noticed very odd lift issues with chines; I agree with the above bug report, something is definitely off with all the chine parts.

[SuicidalInsanity]

I've had a chance to take a look at the chine lift issue, and I have good news and bad news. The good news is I know what's wrong and how to fix it, the bad news is the fix is mutually incompatible with chine attach node symmetry. Chines can be placed individually with proper symmetry, but chine nodes can't be used to attach other chine parts with proper mirror symmetry.

[fourfa]

Couple of minor observations in using this pack recently for the first time -

The G-120 "Vector" engine has an attachment node that seems to float in front of the model, with a substantial open air gap to its parent part when attached. Almost like it's meant to have an auto-shroud but doesn't?

The SP-G Shrouded Solar Array has the 1200K thermal limit typical of the stock naked solar panels, not the 2000K limit of the stock SP-L and SP-W shrouded solar panels

The R-71 Cockpit has an unique all-over reflective texture that is very different than the rest of the pack's cockpits, or the stock ones.  All of the mod's cockpits have a lovely window reflective layer though, and it almost looks like the R-71 window reflections got applied to the whole part?

Thanks!

Bummer-- this would be for attaching a line of them so they snap together, right?

I keep noticing this and forgetting to say anything about it. I just use the offset to hide it, then forget about it by the time I am done playing KSP.

[SuicidalInsanity]

@fourfa: Solar panel and vector attach node are easy fixes, I have my suspicions about what's going on with the R-71 cockpit, but it's been due for a remodel for a while now so it'll get fixed one way or the other.

@Beetlecat: Correct:

if stacking chines they'll have to be placed in 1x symmetry or with radial symmetry instead of mirror symmetry. Probably shouldn't be an issue with normal chine usage, wing root chines, if being used as wing roots will need to be placed without using stack attach nodes.

I haven't noticed this mentioned anywhere, so I'm going to ask here:

Has anyone noticed an unusually high drag value on the SpadeTail component (compared to other tails)?

I was looking at the part Aero data while flying and noticed the drag to be a bit higher than I expected. I replaced the tail with a different tail and the aircraft's top speed jumped from ~780m/s to ~850m/s.

Am I being a bit dense as to how the aero should work vs how it's working, or does this indicate some sort of bug?

[Shrike99]

What in the name of the kraken does it take to keep the NUK-3 reactor cool?

Is it even possible with stock radiators?

I tried 8 of the largest stock radiators, and that only achieved about 81% thermal efficiency with a temperature of 1422K

And shouldn't it be producing around 240 ec/second at this efficiency?

Currently it is producing about 11 ec/second, which i can get from 14 RTG's, at about a third of the mass.

@Shrike99: The first part is due to ModuleCoreHeat being incomprehensible, and the NUK-3 ended up with a Max Cooling value lower than the Req'd Cooling value; another thing to fix next update. The efficiency issue took a bit more experimenting; apparently ModuleResourceConverter parts like the reactor now require an engineer on board to operate at something approaching full efficiency (When did this get implemented?); quick testing showed a drone core would get 5% reactor/ISRU output efficiency, a L0 engineer would get 25%, a L5 engineer would get 125%. I've figured out how to override this, so that will also get fixed next update.

Awesome news, thanks

Question:

When using Community Tech Tree, the J-58 "Afterburn" TurboRamJet engine is available at node "High Altitude Flight," while the stock JX-4 TurboRamJet engine is unlock at the next node, "Hypersonic Flight."  Why is this?  Feels a bit cheaty to have it available one node sooner. 

[MannaroThePatient]

Bug? Both variant of D-ZZY 'Banshee' Lift Fan now require Liquid Fuel, FanIntakeAir AND Oxydizer.

[SuicidalInsanity]

@JayPee: I honestly don't remember. By mistake, probably. I've reupped a fixed version of 1.7.35 that fixes this.

@MannaroThePatient; Banshee fans have always used LF/O by default. The Electric or LF/Air fuel modes for the Banshee are provided via MM patches found in the Extras folder.
