Attitude Control in RO+RP-0


Recommended Posts

So I have another problem with RO and I'm feeling a little stupid here ^^
I just built a probe that really needs attitude control, so naturally I stick on 4-way attitude control thrusters, configure them for nitrous oxide and add a small tank with nitrous oxide, thinking this will provide me with control. However no such luck, the thrusters seem to refuse to fire, and there is no use of NOx shown in the resource panel. Initially I thought it might be a problem with the avionics package I am using for the upper stage (the early 0.813m package) so I tested the whole thing sitting on the pad with the big A4 Guidance Unit, which provides full control for my first stage, but the thrusters still refuse to fire :/

Any help/pointers would be greatly appreciated :)

I went around and around with thrusters when I started with RO.  Usually the problem is the thruster isn't configured for the fuel you're using.  You seem to have checked that, though, so another thing you might check is that the parts between the thrusters and the tank allow cross-feed.  When I mounted my thrusters on a capsule it didn't work until I configured the capsule to allow cross-feed.

One thing I noticed in my install is that if the RCS is on something 'before' the fairing, then I jettison the fairing the RCS on the earlier stage stops working. I'm not sure if this is RO, RP-0 or something unique to my install, but I've had great success just 'building around it' by only putting my RCS on whatever is inside the fairing. Not sure if that helps you at all, but its worth looking at.

 

Also, is your RCS activated? Don't feel stupid if its not. I've literally thrown stuff at my wall out of frustration that my craft won't turn, only to realize I forgot to hit 'R'.

Oh lord, I don't think I have ever embarassed myself so badly on these forums T_T I had indeed not turned the RCS system on >.< I have been flying spin stabilized rockets so much that I completely forgot...

I humbly apologize to all of you for wasting your time
