Please help out a newbie...this is the first time I'm putting together an ARF (or pull pull or any RC related stuff for that matter). I've read a bunch of posts on here about pull pull systems but they are beyond me and don't answer some basic questions I have. This is for a 3D Mayhem with a OS .91 2 stroke engine and 5625mg Hitechs. Here they are:

- how do I accurately figure out the exit holes of the cables
- how low/high do I place the control horns on the rudder (i know about the hinge line and ackerman)
- does the cable need to be parallel to the fuse or can it go from the servo arm to the bottom of the rudder
- does the servo have to go with the output arm closer to the rudder
- will the stock arm do (2" arm, seems very solid)
- what holes do I need to put the cables in (at the servo and at the horn)
- how do I test the tension of the cables inside the fuse once they are all installed?

I know these are a bunch of questions. Thx in advance
