newbe in search of.......
First I would like to say I am impressed with the knowledge and the great advice you give to others. Question one, fuel tank placement, is behind the engine the only place. Also I have not seen a good picture how rudder linkage works. (from servo too rudder)

RE: newbe in search of.......
I agree, we have a good group of guys here.
As far as gas tank placement..... Behind the engine seems to be the norm and easiest to start. Mine is located in the middle of the hull below the engine and is harder to start. You also need a pressurized fuel system to run this set up. I like having the tank as low as possible to help with stability. Depending on your set up, the gas tank can be located almost anywhere as long as the lines are pressurized and you don't mind choking the engine to keep the fuel up while starting.
As far as rudder linkage, I am not sure. I just run a push rod directly from the servo to the rudder control horn. Others have better set ups, and it also depends on weather it is a single rudder or duals.
Hope I was some help...

Here are some to give you ideas.
This is a smaller airboat. It uses a solid 1/16" music wire pushrod. Very simplistic. You will also notice that the servo sticks out above the deck. The radio compartment is covered by a cowl which allows this type of setup.

This is my Dumas Swamp Buggy. It is set up so I can use either an air rudder or a water rudder by loosening the control arm, remove the rudder, insert the air rudder with control arm attached, then placing a collar between the bracket lugs to keep the rudder post secure and tightening the set screw for the control arm.
Also an interior shot of the radio gear.

For my boat I use two fuel tanks... a small "header" tank behind the engine ( 2 oz) with a larger tank (20 oz) sitting about six inches below the engine however this tank is now being moved to the front of the boat (to move some of the weight off the transom), the total distance will be about 3 foot and yes I am using a Cline fuel pressure system ( supplies 2-12 psi pressure for the tanks) which works like a dream.
As for the rudder this is a diagram of how the dual rudders are currently set up on my boat.

If you are running gas (2 stroke weedeater motor) you can use an IV bag from medical supply houses or used ones from your local animal vet. Only one line from bag to carb, thats it. No water to get in bag and on foaming for air to get in carb. Works great. John

Thanks for the info guys. Just yesterday I went to the local hobby shop and bought what I needed to get started with my first project.
