Default T/F Stinson Reliant Servo/Radio Questions

I posted this question on RC Groups but thought I would give it a whirl here as well:

<span class="Apple-style-span" style="font-family: verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif; font-size: 13px; ">
I'm slowly making my way thru the SR-9 build and it's going slowly. I'm in no rush at all as I have been out of the hobby for many years. This is more of a time-passing project that, when it is finally done, I may have the skills to fly.
I have bookmarked a few build threads that have helped but my specific question is what servos are recommended for this plane? The build threads I have followed are all a couple years old and the equipment used in them may be out of date.
I am planning on buying a new radio, either the Spektrum DX7 or the Futaba 7C. I can either get these radios as transmitter only or get a bundle including radio, receiver and servos.


Tower Hobbies suggests the following servos:

Servos: 6-8 (optional flaps)
3-Standard Torque (42 oz-in)
(1-Throttle, 2-Flaps Optional)
5-High Torque (at least 75 oz-in recommended)
(2-Ailerons, 1-Rudder)
(2-Elevator High Torque) or
**NOTE: per designer, one super torq HCAM0191 could be used)

The bundle servos from Spektrum and Futaba:

The Futaba S3152 Digital Standard High Torque Servo
SPECS:
Speed: .22 sec/60&deg; @ 4.8V/.18 sec/60&deg; @ 6V
Torque: 69 oz-in @ 4.8V/87 oz-in @ 6V
Weight: 1.5oz (42g)
Length: 1.6" (41mm)
Width: .8" (20mm)
Height: 1.5" (38mm)

The Spektrum DS821Sport Digital Servos:
SPECS:
Torque: 72 oz/in @ 4.8v, 88 oz/in @ 6.0v
Speed: .19 sec/60 deg @ 4.8V, .15 sec/60 deg @ 6.0V
Size: 1.50 x .94 x 1.47 in
Weight: 1.5 oz
Ball-Bearing: Single
Motor: Cored

If you were me, would you start with one of the bundles or just get a transmitter, receiver, and servos separately. If buying separately, which servos would work the best and keep the price down?
Also, if you have used both the Futaba 7Candthe Spektrum DX7, which do you prefer and why?
Thanks in advance</span>

To be honest with you, I'd go with the DX7. Reason being, it is a good 2.4 radio with plenty of features. The DS821 servos are more than enough power, as thats what I puting in my 102" Meister FW-190. The AR7000 is a tried and true receiver. The price is right in line with the latestest and greatest 2.4 ghz. It really boils down to preference, but I think you'll be very satisfied with the DX7. The only thing I would change is going with a larger MA battery than the one supplied with the radio.

The only thing I use is the Hitec HS-645MG. I know that it is overkill for some things but at $24.00 bucks a piece, that is less than the 821's and it will cover any future need. Just my thoughts.

I'm with you on this one.

These are great servos at a reasonable price. The TF Stinson does not require this much servo, but the price makes it hard to resist.
