Default Pull-pull systems and bellcranks...

I'm having trouble trying to layout the fuse servos (thottle, rudder, and elevator). Here are the basic problems:

1. Becasue the engine is mounted inverted the trottle control rod has to enter the fuse just about a 1/4" off the floor.

2. I'd like the cables for the rudder pull-pull system to run close to the floorboard (under the pilots seat)

2a. Is it OK to use the servo arm instead of a bellcrank (the large Airtronics arm is a perfect size match for the rudder control horn)?

3. Ideally, I'd like to have the elevator pull-pull cables attached to a mock-joystick which would be moved by the servo via a short control rod. But where to put the servo?

The real problem is thinking of a way to install the servos so that I can get at them for adjustments. I'd appreciate any photos of the "guts" of your planes that might jog my mind into finding a solution. Thanks.
