[FTC]: Servo specifications?

Yes.

1) Take a simple postal scale and measure the force it takes to lift the scoop at some reasonable distance from the pivot point.

2) Multiply that force by the distance from the pivot to get torque. Use a consistent system of units.

3) Compare that required torque to the torque rating of the servo.

I dont work for servo city, but they have great info and FTC approved parts on thier website...

Here is the specs on the standard servo:

You might consider upgrading the servo to a quarter scale servo which is newly legal for 2013-2014 which will give you a significant increase in torque:

Another option is gearing the servo:

Also something that helps using servos are servo blocks that take the sideload off the servo horn (a common breaking point for servos):
