I have a set of 4 Futaba S3003's and a set of 4 Futaba S148's. I looked them up on the Futaba website, and the specs are quite different, so I'm not sure which ones to use.

@4.8v:

S148:

Speed: 0.28s/60 deg
Torque: 33 oz-in
Weight: 1.6 oz

S3003:

Speed: 0.23s/60 deg
Torque: 44 oz-in
Weight: 1.3 oz

Do I want the speed or the torque? I'm using them in a 60" wingspan trainer, so do I really need speed? The website also calls the 148's "S148 Precision" so does that mean they are really more precise?
