Thanks! That was quick

Its really meant for Earth/Kerbin and for relatively low orbits below GEO lets say. Once the orbit starts getting too high that atmosphere factor matters less and less.

Just added this. Idk why I didn't together with the other variants, no changes to the model were needed, only the config . The top attach node is now moved to the same position as the bottom (but facing up).

Despite 2.5x KSRSS and JNSQ being roughly 1/4 the size of our solar system, the atmosphere height is roughly the same (90 and 85km respectively vs 100km Karman line on our Earth). The orbital altitudes on the other hand are scaled directly to system scale, GEO in these KSP systems is roughly 1/4 of the IRL GEO. So basically this formula will give you a decent approximation to scale IRL orbits to KSP (RealOrbit_km - 90km) * 0.25 + 90km = KSP equivalent orbit in terms of relative performance.

Drag issue on the jettison SLA has been fixed with a slightly modified custom cube and fixes to the B9 switcher that was preventing it from taking. Here a base engine config Saturn IB launching to equitorial 110x110 in KSRRS 2.5x with about 200m/s spare in the S4B With the upgraded 1973 engines can make 180x180 at 50 degrees launching from Kennedy in KSRSS (Skylab orbit scaled to KSRSS). 0.4 deg/s pitch rate and 100m/s pitch start is essential though.

I've made a commit which prevents drag cube (and FAR voxel) recalculation with the B9 switchers on the capsules and heatshield variants. Its likely the addition of the switchers late in the dev cycle is what introduced the problem. It survived without any abnormalities under similar circumstances as my earlier test which was a lunar return in JNSQ with a 35km periapsis with both regular and offset CoM. Please have a look and let me know if its working for you (or anyone else with similar problems). The potential fix is on both master and dev.

Sorry I got your earlier comment backwards. I've managed to reproduce the issue but Im not sure whats gone wrong as it was fine earlier. Will need to dig into this.

Only about 2 years late, here's some variants of the Delta IV fairing and standalone payload adapter. The fairing base can now switch their top nodes from 2.5m to 1.875m The structural adapter can now switch from 3.125->2.5, 3.125->1.875 and 2.5->1.875

We've updated the craft files with most of the key variants with the last release. If you feel there are interesting or important variants still missing happy to take a look at what you have Please do keep in mind craft files meant for inclusion must be made on an up to date KSP, on a clean install with just BDB and its dependencies (so there are no rogue modules, its generally harmless but it throws an error that alarms some people). Uh can you check on a more recent version of BDB?

Added a silver foil switch to the TRS core and prop kit

No clue at all. Its a simple hinge part with a single pivot. The only thing thats different to typical squad robotics is that it has a skinned mesh/armature for the pulley cable.

Its too bright

Orbital cannon/SIM ATM now on the dev branch. The instrument will track the sun upon deploy. (unfortunately the experiments cannot be coupled to deploy anim in this case) Available with and without the sim bay support structure.

If you are using the SLA (spacecraft adapter) that has jettison panels there is a drag issue that prevents saturn IB from getting to orbit. If you use the version with built in hinged panels Saturn IB can get into orbit although its challenging (the real rocket had thin margins too). BDB in general works with 2.5x without additional configs. Its balanced specifically for that.

I am testing with custom defined drag cubes that override generated ones. Please dont take this the wrong way, I know you're trying to help but I've spent ages making little progress on this and am quite tired and frustrated with this problem. I am not inclined to go on further wild goose chases unless someone has considerable knowledge on aero issues and can present me with solutions that are highly likely to work.

afaik in the stock aero system drag is calculated based on drag cubes only. The colliders only come into it for shielded parts and act as a bounds for the shielding radius. I believe in FAR the drag is calculated based on the visual mesh.

The Titan II GLV has been tested extensively with the standard Gemini spacecraft and configuration. If you're packing extra monoprop to get more performance from your Gemini, then you need an upgraded launch vehicle most likely. There seems to be some bugs with the rotation module, cause is uncertain (could be root part related) and solution even less so. In the long run remade IVAs with the correct orientation would be a permanent solution but thats not happening immediately. The problem with SAF is that the staging events for the fairing sides and the top node are not necessarily coupled together, and we have the problem of the second decoupler for the LM which is handled correctly by the current SLA module which hides it until after petal staging. Maybe something could be worked out but I dont want to add a 3rd SLA type and it would be better if the existing SLA could be fixed.

The B2 was only used on Delta III and IV so I wouldn't lose sleep over that.

Default SA-6 I think. They were added a little while back but got soon overwritten with old files while doing some texture fixes. This is probably the current dev or master branch (where it was fixed again a couple of days ago).

The added cargo bay modules should provide the appropriate shielding now and I've just increased the shielding radius on the standard jettison panel. That said the jettison SLA still underperforms the hinged one due to part drag. The jettison SLA still needs a custom drag cube and I've been experimenting but if someone can provide one that will deliver the exact same performance as the hinge one I would be very grateful. I get 350 m/s of drag loss with the Skylab 4 craft file (with original engine configs and in KSRSS 2.5x to 110km 0 degrees using Mechjeb PVG for a consistent ascent). But havent been able to reduce below 600 m/s drag loss with the jettison panel which eats up the margin to get to orbit. I'm kind of running out of patience with this one since engine upgrade or the alternate SLA can work and I've been bashing my head against this for a while. Im a little surprised by this since we've not had reports about reentry problems with the Apollo. The configs were fine tuned by JSO ages ago and should still be applicable to the new parts and the behavior seemed ok in our last round of testing. That said we can take another look but I'm curious if other people are having similar problems. I've fixed the science transfer issue and about control points can consider those, I dont see any harm.

Not just dev but in the master and release as well. This was added several weeks before release and I've verified that its working today even.

its just an issue not tied to any branch. It was always planned for after the initial Saturn/Apollo/Skylab revamp

Its planned. Im hoping to get started on it during this dev cycle https://github.com/CobaltWolf/Bluedog-Design-Bureau/issues/974

Thats a deprecated part deliberately hidden. Go to github, click on the button that says master and switch that to 1.11 development. The link in the OP is outdated as it used to point to apollo saturn dev which is deleted.

Alright the IVA is now fixed and we also now have Saturn IB decals again thanks to Viper.
