Servo (9451/9351) for Fury Extreme

[Knud Pedersen DENMARK]

My +700 old Futaba S9252 in my Fury Extreme is starting to give up.
At center stick the one of the servo is not standing still…..

I am running a Fromeco Arizona regulator…(5-6volt)

I would have chosen the S9451, but I can see a lot uses the S9354 (at least on the synergy)
At 6V the 9451 is fastest – but the 9351 is stronger, and thereby maybe faster then the 9451 if load is at +3 kg pr. Servo……….

Which servo would you prefer for the Fury Extreme (6V)??

Futaba S9252
4.8V 91,60oz-in(2,6kg) 0,14sec/60°
----------------------------------------------------------
Futaba S9255
4,8V 112,0oz-in(3,18kg) 0,17sec/60°
6,0V ??oz-in ??sec/60°
(have read that Nigel Brown uses this servos on 6V in his Synergy)

Futaba S9451
4,8V 96,6oz-in (2,74kg) 0,13sec/60°
6,0V 120,8oz-in (3,42kg) 0,10sec/60°
----------------------------------------------------------
Futaba S9351
4,8V 153,0oz-in (4,34kg) 0,16sec/60°
6,0V 192,0oz-in (5,44kg) 0,13sec/60°

Hi Knud

Correct conversion is oz-in to kg-cm is to multiply oz-in by 0.072 to get kg-cm

That means:

----------------------------------------------------------
Futaba S9252
4.8V 91,60oz-in(6.5kg) 0,14sec/60°
----------------------------------------------------------
Futaba S9255
4,8V 112,0oz-in(8kg) 0,17sec/60°
6,0V ??oz-in ??sec/60°
(have read that Nigel Brown uses this servos on 6V in his Synergy)
Nigel does as do most of us down under. The Arizona reg gives you the option of running the machine between 5-6 volts.
----------------------------------------------------------
Futaba S9451
4,8V 96,6oz-in (6.95kg) 0,13sec/60°
6,0V 120,8oz-in (8.7kg) 0,10sec/60°
----------------------------------------------------------
Futaba S9351
4,8V 153,0oz-in (11kg) 0,16sec/60°
6,0V 192,0oz-in (13.8kg) 0,13sec/60°
----------------------------------------------------------

Given that you have been happy with the 9252 servos, I would suggest that any of these would be fine. A number of us are using 9252, 9451 and
9255 and they all work fine!

hope this helps
