Looks like OPT updated to include FAR compatibility recently. Hopefully that will fix the issues I've been having with it. Thanks again for everyone's help and suggestions!

Ah, that would explain why the addition of the drag cube didn't do anything, lol. Is that .cfg a MM patch? Do I just dump it in my GameData folder, or do I have to cut and paste that code somewhere?

Yeah, that's why i tried implementing the drag cube myself as per this post in the OPT thread. It's possible I didn't paste the code in properly, so I'll go recheck that. Immediately aft of the cargo bay is another fuel tank. From fore to aft it goes capsule, adapter, science lab, cargo bay, fuel tank (empty), engine mount. On a side note, I finally remembered how to embed URLs in text! Go me! - - - Updated - - - Upon further scrutiny, it does seem like i had the drag cube code pasted in after the final bracket in the .cfg. However, moving it to the right place doesn't seem to have helped the cross-section at all.

Crzyrndm, 1) Ok, that's what I had suspected, but good to have the reassurance on it. 2) I didn't notice any asymmetrical voxel distribution on the B9 wings with 15.2, but I'm updated to the dev build now, so all should be kosher. I hadn't considered the posts per page issue, so I'll link to specific posts from now on, thanks for the tip. Sal, I'm not using FAR's flight assist on this. It seems to cause too many oscillations. Same can be said for MJ and standard SAS. It's all "manual/mechanical" trim for me! After adding the drag cube code as referenced in my last post, the cross-section curve still looks messed up, so I replaced it with a regular fuel tank, the results are below. Looks like the cross-section issue is isolated to OPT?

Just downloaded the dev release as recommended. Also updated B9 Proc wing. Haven't retested yet, as the cross-section curve sill looks like this: http://imgur.com/HkmmkE4 I think it might have something to do with the issue being discussed here: http://forum.kerbalspaceprogram.com/threads/97525-1-0-2-WIP-OPT-Space-Plane-v1-6-9/page65 I'll paste in the fix that they're suggesting and recheck the curve. On a related note, do you know if the stock physics.cfg has any bearing of FAR's calculations? I remember patching the 1.0.2 aero back to 1.0.0 after seeing several complaints here about the increased drag and whatnot. Just wondering if I should be reverting that .cfg back to its' 1.0.2 specs. Also, sorry about my link formatting. It's been a while since I was a forum user and the intricacies of text formatting have escaped me.

Thanks SAI, I'll have to remember that formatting for future use. Spacestation/MailletC, I placed the intakes individually to avoid the known asymmetric flame-out bug, but I'll add the build-aid to my mod list so I can be sure everything is paired up correctly. Capi, I have the newest version of FAR (0.15.2 "Ferri"), but I'll go download the new B9 Proc wings now and recheck. I know the derivatives at 0k/0.35 are red in some cases, but I usually don't rotate until ~120m/s. That most likely means there's not enough horizontal wing surface for the weight of the craft, so that's probably something I'll have to address in addition to the vertical stab/rudder area. As for the simulator tab, any help/advice is always welcome. I'm operating on the "green is good" principle, but a better understanding of WHY is never a bad thing. aj, I'll look into moving the intakes back as well. Not something I had considered before, but it certainly makes sense. As far as the craft discrepancy goes, the last few pictures in the album are of a different craft, but illustrating the same issue. The first half of the album is the craft that I built. Thanks again to everyone for your input thus far. I'll go make some tweaks and report back.

Hi all, As the title says, I'm having some issues with Yaw forces that I don't think should really be there (I could, of course, be wrong). I did some searching and didn't really seem to come up with anything. I'm using B9 Proc-wing, OPT, FAR and AJE (Many others as well, but these seem to be the relevant ones). I've placed the engines individually after placing their respective intakes and I don't seem to be getting any unequal thrust. I haven't even gotten high enough to see if the engines flame-out evenly or not. Please see the picture attached below and if you need any more info, let me know and I'll do my best to gather it. It's probably worth mentioning that I haven't spent much time with aircraft in KSP and this is my first solid attempt at an SSTO. I know it's lacking sufficient orbital engines on the design right now, but I wanted to try to get the high altitude/speed flight mechanics down before trying to work on the orbital bits. Aero Overlay (Not sure if this album will show up properly. I also put in some bonus pics of the same phenomenon occurring on an SR-71 model from the MK2 Expansion mod) Thanks in advance for your help, guys. This community has be a HUGE source of great info and mods. Keep being awesome!
