Thanks guys! I really enjoy and appreciate all the feedback I get here.

I sanded away some if the composite around the servo slots to where the plywood supports start. The 9411 should drop right in. I am going to go with the 8411 on rudder, its a few grams lighter than the Futaba.

So it comes down to the stab. The Futabas are lighter there, and also a lot less expensive. I don't understand the draw to run one brand of servo, but it is there. But the money saved on those servos would afford a new wing tube. I honestly thought it was full of concrete when I took it out of the box, LOL. I guess that foam is pretty dense.
