Yaw does not function on my large vessel

[ebix]

So I have a large craft http://imgur.com/KNSfNkX (Not sure if there's a better way to upload crafts, sorry for my noobness). If you look at the image you can see I have two large reaction wheels at the top, and some linear RCS ports at 3 different locations on the craft (near the top, somewhere in between and CoM). My RCS ports have 8x radial symmetry and I have check and visually they are all functioning.

Now the weird part. No matter how much I lean on D or A, there is no movement in that direction. None at all. Not even a little. The craft eventually starts to pitch and roll as if I'm pressing against an invisible wall. Similarly if I try to roll and then stop all my motion and then pitch forward (like a 3 point turn in order to do some yaw), instead I just roll back to my original location when I pitch. This only started happening in 1.1+ However I never had a vessel quite this large before, although it doesn't seem like that should effect things given my vessel design. 

Has anyone seen this before? It's driving me crazy.

Seems more like a tech support question, moving over to Support for modded installs.

Try putting mono prop on the ship, if there isn't. If there is, put reaction wheels on the other end of the rocket.

There is monoprop on the ship.

I would say this is the solution if there was minimal movement in Yaw, and that minimal movement was duplicated by pitch and roll. But there is NO movement in Yaw. Additionally, since reaction wheels have equal power along all the axis I can't see any reason why pitch would work but yaw would not. 

Also, to clarify the behavior I'm seeing, If I pitch forward the ship also starts rolling and if I pitch the other direction it starts rolling in the opposite direction, this effective confines me to about a 3rd of my navball, so it's a very destructive problem

Sometimes I find it doesn't work correctly when you have a reaction wheel on one side (radial) but not the other. But yes, this is unusual in behaviour. I notice that the COM may be off, can you try with another craft with a. A COM in line with reaction wheels and control module and b. A craft with pretty offset COM compared to reaction wheels and control modules. If this does not help at all, I assume it is a bug that you'll need to try to find in which mod. Also try this in stock.

 

EDIT via merge: try bigger reaction wheels too
