Why is it that the

Why is it that the Russian's never put a top Rudder on the kilo?

Look at the newer variant

Look at the newer variant Lada class. They have added one.
But, they went many years with this very successful design. It apparently turns fine without the upper.

They didn't put a top

They didn't put a top rudder because that would cause a nasty sound effect with the six bladed propellor. With the current seven bladed skewed propellor it wouldn't be so much of a problem and they can probably add a top rudder now to improve steering. With the previous engine and without the skewing technique, the six blade propellor was the better option for them, the rudder had to follow that.
Of course they solved the manoeuvrability issue by enlarging the lower rudder and adding the horizontal end plates on both sides of that rudder.
Of course that also means an improvement in steering on the surface, something more important for a conventional submarine and probably an advantage for the Kilo over any other conventional sub.

Wayne, what is the appendage

Wayne, what is the appendage back of the sail on the last Kilo-picture where she is morred to the buoys?

Damn, that pumpjetsection is big. Must be real heavy, and with the dive-planes placed on it, weird.. I guess they did some work before trimming her correct. Do we know how effective the Alrosa pumpjet is? What about her max speed, is it stated the same as other Kilo's? I always beleived a pumpjet needed alot of power to be effective, and this thing is running on batteries
I have seen a closeup of the Alrosa pumpjetsection somewhere, will post when I find it.

Anyone built a model of the Alrosa?

Pumpjet Kilo

Lociz,
Check out Big Dave's dockyard section. He converted his Kilo to a pump jet variant.

I have a Manley 1/96

I have a Manley 1/96 Kilo I will be building to Alorosa specs soon. Right now I am on another project. Big Dave did some great work on converting his.
In book two, I will cover the Kilo. I plan on including the Alorosa. It has been a favorite of mine since I saw it in Sevastopol, Ukriane in 2005, even though the performance has been less than expected from the Russians. It is still a milstone boat. First known Russian pumpjet put into operation.
The pictures of the pumpjet itself (the ones you are talking about), I will put in the book for sure.
At the moment, I have someone in Sevastopol who is trying to get me better pictures.
