Default Servo Brands: The Good, The Bad.

It's that time to upgrade my servo, been searching a lot on the forums and can't find a thread that talks about servos in particular. Can you all tell me more about them in general, different types, what brands to stay away from, What brands are a bit better. You know, general stuff. Mine (Hpi SF-1) is making constant chattering noises and no power when I'm on the throttle. I have the hated HPI S2F. The old school with the 57k warp motor and receiver. Not sure if the year. But it must be old to be discontinued and replaced with the motiv.

I have a Savox 1251mg which is about a year old now. Still running very strong and precise. The only issue with Savox servos is that they tend to be power hungry, you want a esc with at least 2.0A BEC. I recommend it to anyone looking for a budget servo.

I purchased a Futaba S9551 Servo last month but haven't received it yet so I can't comment on it. But everyone says its a very good servo.

What car are you putting this servo in? Are you racing? I prefer Low Profile servos as modern 1/10 onroad chassis don't have alot of room for electronics. But they do cost more compared their similar spec, standard size servo counterparts.

I have been lucky with all my servo's as well,

I havnt had any issues with my Futaba S9551 after 2 and a half years of use and the Savox 1252mg in my F1 is great as well.

In my 21.5/VTA car I picked up a cheap PowerHD DS-1207TG servo from Rcmart and really like it for the price, seems to take a pounding and is quick enough, and doesn't have any centring issues..

I don't seem to have any power draw issues other people seem to have??

In my buggy my 15 year old Futaba S9402 is still going strong I will replace it one day if I could be bothered.

I run a savox 1251 and a Futaba BLS551

On paper they have pretty much identical specs.

I was happy with the savox, but the Futaba is another level again. Despite being the same speed on paper, it is definitely faster. Also quieter and smoother. Apparently less power too.

But it does cost double!

I would recommend both for 1/10th TC pending your budget.

Sold both my Savox 1251 servos. And yes, my Futaba brushless servos were on another level.

Sanwa/Airtronics servos all the way for me. In both nitro and electric. I have never had one fail on me. I use savox servos in some of my bashers but all my race cars have sanwa's.

I'm using both the Sanwa SDX801 and the Savx 1251 / 1252.
The Sanwa feels definately faster and more precise.

Sanwa SDX801 is the main servo of choice for most of the top TC racers...

The best: Hitec Ultra Premium, KO Propo

Good: Futaba, Hitec. But it depends on model.

It's rare I run anything else.

The good : KO, Futaba, Sanwa/Airtronics, JR

The not-good-enough : anything else

Once you've tried Sanwa you never go back IMHO.

Futaba. I have a S9550 that has been in at least 6-7 different cars. Always fast, smooth, quiet. I have a Savox in my other ride and I will probably sell it for something else. Nothing special about their stuff at all to me, and power-hungry as some say.... it came with the roller I bought and that is why I have it. Not bad but not my first pic, ever.

i have all savox servos for 4 years now and not a single problem with them. ive always run futaba or airtronics so never had the "Glitch" problem either.

I recently switched to 1252mg for my touring cars as they were on sale and i was curious about the 07 speed. used to run 1251 which was very good already. those are now in my nitro car.
i dont just recomend them as good servos for a price, they are simply good servos at any price. they could probably charge more for them and people would still buy them in droves heh.

I use JR, KO, Futaba. I rate Futaba (BLS 551 which is a modern version of 9551) the lowest of the three with JR and KO equal. The JR though had the speed and twice the torque of the KO (RSX one 10) about 7 years ago when nothing else came even close. They don't make low profile in these high torque/hi speed servos though (the KO is low profile). Savox is a cheap chinese copy of the old JR 8911 which has morphed into the 9511 I have had for this time. There are now (about 4 years old) hi-voltage JR servos which are down into the .05s reaction time and zero play. Pricey but again you get quality. None of mine failed ever, but they cost close to the price of a top end TC kit.
