Nic hes tring to say what i did in short. But the idea is to place (one) servo say in the right boom. Now run your push wire/ or push rod to the right rudder stab.(normal rudder setup)
Now most likey you will have to place this on the trailing edge of the rudder to work right but attach a very short control horn, or something to attach a carbon push rod too. Then run that across to the left rudder stab and attach in the same way. So one servo will control both rudders

Jayz said it right but I worked so hard on the drawing I had to post it
Okay, this makes sense now. Thanks for taking the time to do that, Okie! I rather like your drawing, haha.
Hmm.
So, while it's practical, I don't like being able to see the exposed rod. For the servo I'll be putting all mine internal, I'm not a fan of having them pop out the sides. It's an easy and effective way to do it, the FT style, I just don't care for the visual.
So It looks like there is really two options here:
1.
Use two servos
+Using a Y cable will save on a RX port (same as 1 servo)
+Visually better
-Additional servo needed (cost)
-Added weight (9g, does that even count? haha)
2.
Use one servo
+Cheaper
+Lighter
-Rod is exposed
I think I will go for option 1 in my build. Option 2 will be available for anyone who wants it
