Well its here, and undamaged!

While unpacking and checking it over I took the measurements needed to figure the servo size needed. The measurements I got are to follow:

Aileron
Length: 18.5in
Cord: 3
Assumed max airspeed: 120mph
Max control deflection: 15 degrees
Max servo deflection: 30 degrees

Elevator
Length: 15.25in
Cord: 3
Assumed max airspeed: 120mph
Max control deflection: 15 degrees
Max servo deflection: 30 degrees

Rudder
Length: 10.25in
Cord: 5.25
Assumed max airspeed: 120mph
Max control deflection: 20 degrees
Max servo deflection: 45 degrees

Flaps
Length: 13.25in
Cord: 3.5
Assumed max airspeed: 80mph
Max control deflection: 45 degrees
Max servo deflection: 90 degrees

While I have my own formula it si so similar to this one and it is easier to use. See the URL below:

the results are:
Aileron each = 40oz-in
Elevator each = 33oz-in
Rudder = 70.5oz-in
Flap each = 95 oz-in

Plug my numbers and see if you get the same numbers
