XER987: Up until this coming season, I have always used standard servos. But starting this year I will be using a KOPropo 2173. The specs on it are: Metal Gears, Analog, and speed of 114oz/in @.09sec.

The reason I'm going with this unit is because I have never heard a single bad thing about KO servo's and I have seen this particular servo in action and like it.

If you have the extra $20 or so more it takes to move up to their digital unit 2143, and you want digital, you cant go wrong with KO.

Manufacturer: Futaba
Model: 9450
Torque: 111 oz/inch
Speed @60: 0.10 sec
Digital servo.

Pros: Full metal gears, ball bearings.
Cons: Incompatible with some older radios. Not my case (then no cons).

I have some servos on all my models, varying from a Futaba 9101 on my Pro10 car to a KO 2001 Fet servo, passing thru several 9450 units. If I need another servo in the future, the 9450 unit is a straight buy for me.

I also use the Futaba S9450 servo. Characteristics are off course the same as above.
Prime reasons I use one: metal gears, digital, Futaba is first class brand.
I had a Hitec servo and also a cheaper Futaba with plastic gears.
The Hitec servo always lost its middle point and the Futaba stripped the plastic gears three times.
If I had to buy one the S9450 would be my choice: fast and strong. Until now (about seven months of racing) not one problem with it.

KO PS713, 6kg/cm(?), 0.1s/60deg - this is KO's non-digital "classic" 7.2v FET servo - half the price of the newest digital models.

futaba s9402 - 111oz-in torque, .10sec/60, non-digital. i plan to upgrade to a 9450 (digital) and put the 9402 in my monster truck. the 9402 is a tough and reliable servo, i've had it in my tc3 for over a year with no problems. my previous servo was a futaba 3003 that gave up after a couple of months.

question: how are the high torque hitec servos? if they are reliable enough, maybe i'll stay with the 9402 on my touring car and just get the less expensive hitec servos for my truck. thanks for any info

MANUFACTURER: Futaba

MODEL: FP-S148

TORQUE OZ/IN. : 41

SPEED 60DEGREE/SEC: .22

DIGITAL OR STANDARD: standard

WHY: BECUASE IM CHEAP, LOL!! and also because my car handles great with it and everyone else that drives my car thinks that i have a high speed high torque servo. plastic gears = ghey ...a hit at the perfect "death" angle will render the servo USELESS because the gears will strip, thats the only problem i have with it

Futaba S9402

My dad has a HiTec 925MG, it works good, but I've heard a few people say they have centering problems. I dunno about that. :P

What are the pros of digital anyway? They center better? A good analog servo doesn't have any noticable centering problems... I also read that digital servos suck power..

Did you not see my link at the top. You'll need Adobe Acrobat to read it though. If you don't have Adobe Acrobat you can download it from their site free of charge. A digital servo will give a greater response along with 6X more holding power.
