Flying the Space Shutle in RSS+RO

[skoy21]

So, I’ve been playing KSP with RSS + RO + most recommended mods some time now, and I thought to give it a try to build and fly a space shuttle. I used MK3 parts, rescaled Big S Delta wings with the Elevons for control, RS-25D Engines, AJ10-190 for the OMS, ET and SRBs from RSB.

It has enough dV and TWR, and i managed to get in orbit but... I had no control over it when that happened (every time), and I couldn't see it...

Actually, after it gets a couple hundred dV after launch, it starts loosing focus on the screen, that is, the vehicle slowly goes away, and I need to zoom out to be able to see it (in every camera mode), and after a while, the craft is so far away from the center of the screen that it looks smaller than a coin on my screen. Finally, the moment it gets in orbit it starts spinning like crazy. The weird part is that it does a "spiral" around its orbit line, like a spring stretched around earth.

It spins away from my screen, in orbit, and there is no way to stop spinning or focus to it...

RCS did nothing, I added a reaction wheels just to check, nothing. I EVAed my pilot and the moment she was out the craft it disappeared into the dark (or blue when I was facing to earth). 

I removed the wings, the elevons, the tail, removed the gimbal of SRBs, nothing again. I even tried going straight up...

Everything else flies great. I have a relay of three geostationary communication satellites, I 've launched Apollo missions to the moon, I flew a custom Ariane, I've built my LV and testing it and it flies pretty good, so I cannot imagine the game is broken somehow.

What could possibly do this behavior?

Forgive me if I am in the wrong section here  

 

Since this is my first post, I would like to thank the Developers of the game, and all Modders out there, for making and contributing to such a great game, that actually makes you think and read and learn and have great fun!!

I think I've had what you describe, once. On a totally different vessel but I don't think that matters. In my case, the camera remained focused on CoM, but CoM started trailing the craft, distance increasing until I could hardly see it anymore. MJ+SAS started to oversteer like crazy, presumably because of the weird CoM. I didn't wait to see if I can make orbit.

The craft spiralling around the orbit sounds as if CoM remains stable while (the visible part of) your vessel is going in circles around it.

Shifting CoM in RO is a well-known side effect of Tweakscale. If you use it, try to make do without. If you don't use it and it still happens, there may be interest in a bug report.

hey,

I'm not a bug expert but I'm flying my shuttle a lot in RSS/RO.

Never had this problem though...

You could try to instal this mod:

If you focus your camera on a random part of the shuttle it should stay there, even when your CoM is flipping like a kerbal spaghetti...

Thanks guys for the suggestions, I'll try both when I get back home and let you know!

I'll try resizing the Wings, it's the only resized part on my space shuttle. Now that I remember, I removed the wings for a test, but it had the same reaction. I will check again if I had something else resized. My other rockets & Satellites are heavilly resized though, and don't have the same problem.

After almost completely disassembling the whole ship, rebuiding and removing everything from inside the cargo bay, I can only assume it was some part messing it all up. I stopped getting this weird CoM thing. Now I only need to manage flying it... It's unbelievably difficult.

Thanks guyz, time to fly!!!

Great job, yeah sometimes ksp has it flawes haha.
