Futaba S9550 Servo

Hey guys, I know alot of you own this servo. I just got this servo and when I turn the servo by hand, the gears inside feel very gritty. I took it apart and nothing is binding but still feels very gritty. Is it suppose to be like that when you first got it?

I experienced the same problem, but it does not seem to affect performance... My newest one still feels gritty after 2 races (I have 3 of these so I'm sure it's normal...)

Does it also make a loud grinding noise of your newest servo? When I turn the servo by hand, not only is it gritty but it was loud. Not the buzzing sound tho...

i'd like to take the opportunity to ppost this question, here it goes, when i visited the futaba site there was a description of the servos, the 9450 and 9451 were described as "DIGITAL SERVOS", while the 9550 was described as a "DIGITAL WING SERVO"

what gives? whats the difference between digital and digital wing servos?

tanx guys in advance

The 9550 is a low profile servo so you can get more space to lay electronics flat in crouded sedan chassis'.

the 9550 is design for airplanes, so they could mount the servo on the wings of the airplane, hence "digital wing servo"

Default metal gears

If you have never had a metal gear servo before, this one will probably feel "gritty" All metal gears are like that, they will get a little better as the gears wear in, also they will be louder than a standard servo.

It is a great servo. I have never had a problem with mine.

The 9550 is a "high current drain" (at start up) servo. Have any of you noticed less run time or less motor performance in your electric touring car/buggy ? Do you run a reciever pack ?

the drain is high compare to other non digital entry level servos, but it's like nothing compare to the motors a glitch from crashing or hitting a pipe may lost more power than using the servo. also with the GP cells you should be able to make run time for 5 min mod race, and if you don't race run time doesn't really matter at all

i think receiver pack is more for assisting the power to the receiver and servo during hard acceleration, or make up for the voltage in 4 cells racing
