Worth the money or just plain overkill???

S9155 Digital High-Torque Airplane
Volts Torque Speed
4.8V 152 oz-in. 0.16 sec/60°
6.0V 192 oz-in. 0.13 sec/60°
VS.
S9451 High Torque/High Speed
Volts Torque Speed
4.8V 96.6 oz-in. 0.13 sec/60°
6.0V 120.8 oz-in. 0.10 sec/60°
I'm wondering if (as the title says) should I close my eyes and go for these ones or the S 9451's are plenty servo for a Raptor 90?
Should I focus more on the speed? I guess 0.03 sec is not noticeable.
Although thinking about it twice is the time it takes me to go from flying to left overs :mrgreen:
Thanks for any input.

9255 is a superb servo also. Centers very well and does the job nicely . Designed for helicopters.

Well, I meant to order the 9155's I by mistake I ordered the 9255's so I guess they'll have to do now. :arggg: :arggg: :arggg:
Is it worth the trouble to change the order???
The 9255's don't seem rated for use with 6V (which I might upghrade in the future)
Anyone using them with 6V???
I knw some people use some 4.8V servos with 6V but I'm not sure if these ones would survive.
Any suggestions are welcome, thanks

Well, someone recomended now to use the S9351's, which they seem to be the same (or pretty close to) the 9155's.
This person pretty much discarded the 9155's (don't know why). Basically he said 9255's or 9351's :dontknow

I just wrote an email to Futaba to see if they can explain me the differece between them (9155 vs. 9351) since I don't seem able to see it, appart from the fact that one is a "car/boat" servo and the other is an "airplane" servo :dontknow :arggg: :dontknow :arggg:
Hopefully this time I get lucky and I get a reply from them :roll:
If anyone happen to know the answer here don't hesitate to post it since I don't have much faith on getting any feedback from them.
