>> The tubing does not reach the servo bays in fact they are about 4 inches back into the fuselage. I am not sure if I should try to secure them or not?

You should always install a cross brace to anchor the rudder cable tubing. Here's my build thread on the Altair 200, towards the middle of the page shows the cross brace for the rudder cable - http://www.rcuniverse.com/forum/m_86..._2/key_/tm.htm. You should also install a short plastic tubing between the two rudder tubing to support the elevator push rod as well.


>> should I also get a digital servo for the elevator? Any suggestion on the servos?

Digitals are definitely better than analogs, much more precise, especially on centering. Use servos with good torques on both ele & rud, it makes snapping a lot more easier.


>> It looks like the largest tank that will fit into the bay is an 11oz Hayes which I think will be okay?

I think the 11 oz should be ok, as long as it will give you at least ten minutes of flying time.
