From the manual:

"Six servos with a minimum torque of 98 oz-in are required–
one for each aileron, one for each elevator and two for the
rudder. A standard servo may be used on the throttle. Futaba®
S3305 servos (FUTM0045) are shown on the model in this
manual because they are a suitable, relatively economical
solution to the high-torque requirements, but there are also
higher-precision servos available if this is your preference."

Now granted, they call for duals on the rudder, so a single 200 would be appropriate... but why do you suggest 140+
on the ailerons? Is this personal experience, or just safe over-engineering on your behalf?

I ask because I am about to drop the cash for this same setup, only I had planned to use the recommended 3305's (99 @ 4.8)
for economy's sake as well, and plan to use the ganged pull/pull for the rudder. I could easily hold out for the cash, and
wait to get, say, 9156's, but the cost differential is just overkill as far as I see it.

Please, correct me if I'm wrong. This is going to be the most substantial aircraft build I've done to date, and although
I feel comfortable ripping through most 3D maneuvers, the last thing I want is for a 1500-2000$ aircraft taking a
dirt nap because I skimped too much on servos.
