What plane, what servos?
I only ask because this must be a 40% because there is no reason to run more than one servo on a 35% or smaller plane with the 8611's, 5995's and 5955's out today. I would of hoped you would of figured out this stuff before buying a plane this big, but we would be more than willing to help out just in case.
If you do the math, a single 5995 at 7.4V is just a little less than three 8411's combined!
420oz compared to 465oz
A single Sekio is a sure bet for 40% planes also btw and removes the need for complicated trays.
1800oz of torque!
I think you are right about the torque of either of these servos being enough but i also think you might want to consider gear size in a standard size servo so maybe two of the 8611 5995 or 5955 servos is a bad idea in a 35% aircraft so he might have put some thought in it before he bought it
