Is S9257 good enough for tail servo?

[psilo]

I am just in the process of getting my 600ESP electronics installed. I have CC 85HC ESC along with Hercules 5A BEC running a Z-Power 600BL on 8S setup. Cyclic servos are Futaba S9451's and I have the Spartan DS760 gyro. I currently have a spare S9451 which has these specs...

Operating Speed (4.8V): 0.13sec/60 degrees at no load
Operating Speed (6.0V): 0.10sec/60 degrees at no load
Stall Torque (4.8V): 97 oz/in. (7kg.cm)
Stall Torque (6.0V): 121 oz/in. (8.7kg.cm)

or a spare S9257 with these specs....
Speed: 0.08 sec/60 at 4.8V
Torque: 2.0kg-cm at 4.8V

Would either of these be OK for sport and light 3D flying? Or would I be better getting something like the Align DS620? I will at some stage get the 8900 for the tail but until then was hoping to use one of my existing. Any comments?

9257 is ok for a 500 size bird or down, NOT a 600 size. A 9451 you could use if you had to but buying a nice tail servo is your best option. 9254, 9256, bls 251, 8900g are all very good tail servos and the spartan can run all of them.

I use the 9254 and the spartan in my 600 and it is fantastic i just upgraded from a 401

Should be acceptable at 6V, just try it before you buy something you don't need yet. By the time you will need its maybe there's one even better out that you'll want.

Thx all

I will run the 9451 @6v for the moment and see how it goes and upgrade to a better servo later. Am running the Spartan with a S9256 on my 600n and that runs awesome so may get another or the 8900G.
