SAS question (mod related)

[Guest]

Somehow I seem to be missing my nice, smooth, controllable 0.22 SAS and have reverted to the stiff, wobbly, uncontrollable 0.20 SAS (at least it's not the sloppy 0.21 SAS, but anyway...) I suspect this is mod related, perhaps because of an engine gimballing mod, and was wondering if someone had an idea about how to correct this travesty?

Here is the list of mods I'm running:

I'll be honest here, I can't notice any difference at all between all 3 SASs.

Before 0.21 it was stiff and wobbly, overusing control authority.

In 0.21we received the better SAS that allowed us to control the craft while it was turned on and wasn't so harsh on the control authority. Unfortunately it was so loose that your craft essentially needed to be perfectly mass-symetrical in order for it to make a burn.

In 0.22 the 0.21 SAS was tightened up to better support unbalanced craft and pretty much worked great.

For some reason my SAS is acting like the 0.20 SAS; I can't control the craft while it's on and it is very stiff. This means that having a high gimbal range on an engine will shake the craft quite a bit.

Sorry, I got nuthin. Do a binary search on your mods?

Are you using the SAS modules from AIES? They do that. Just realized yesterday when my rocket refused to turn...

If not, then I have no clue.

Now that ... that makes sense because the next rocket I built flew exactly like I expected, even with the high-gimbal engine. How in the hell are they still using that old system, I thought it was long disabled? Time to dig into the parts...

Thanks!

I think that anything with the old PID parameters (ki, kp, kd) will still function as an old-style SAS. You just have to get rid of those.

The stock hex probe core actually still has some of those values in its .cfg file, though they don't seem to do anything in that case, maybe it requires all three values.

I only found those in one probe, the AIES UAE 'Cubeplate', which I was not using on the craft in question. The SAS module I was using was the AIES DV4 - Advanced S.A.S which only differs from most everything else in that the ModuleSAS declaration comes before the ModuleReactionWheel declaration. Everything else usually does that in reverse order.
