Thanks to all, and thanks for the servo analysis calculator phillybaby. I am still in a quandary in my servo selection for this 25% Edge. The best servo I have right now is an Airtronics 94158 servo which has 145 in/oz of torque and .10 sec per 60 degrees rotation according to Airtronics. The rest are standard servos. My thoughts then are to put this on the rudder. For the elevator I can't decide to go twin servos like a HS-225MG or a stronger single like a HS 545/605/or 625. I will play around with this servo analysis calculator and see what it offers.
