I've been using 2 ACE 1015s on my Revo all year with no issues and plan on running a pair of them on my truggy next year!

JR 9100S 180oz/in @ .06 second transit time

JR 9100T 370oz/in @ .15 second transit time

So far I havent found any servo that compares to the JR 9000 or 9100 series servos. It also depends on application of course, for buggy these will be perfect, maybe overkill, so you may want to get a higher MAH RX pack.

I am going to be trying the Futaba brushless servos out for my touring car, as I feel that any faster than .10 second transit speed in that application will hurt my driving, whereas in the 8th scale buggy, I love the JR, but find that .10 second transit speed is a good sacrifice for twitchiness and control.

I've been recommended Ace servo's so i'd suggest them. I'll be getting them next because the figures look good and are very reasonably priced compared to others

Chaz

Are those digitals? If not, don't believe the speed ratings.

Also, while a .10 DIGITAL might be too fast for some it's a minimum for more seasoned drivers. A .15 analog is like driving on qualudes for me.

Wow - Great responses! Thank you!

Xray Eddy - I have a 9000s in my '007 and it IS FAST!!! Hang on Dude!:

The JR's are digital, and from bench tests only, the numbers seem legit.

Wow. No talk about Airtronics. I know they've been changing in the last few years but I expected at least one person to recommend them. It's good to see all the specs also. I'd like to try Hitecs someday but that means I have to buy aluminum horns. Is there a reason hitec uses a 24 spline output?

I assume the companies go with smaller spline counts so the horns can have more range for adjustment. Like a claim to Fame. They say 25spline is stronger. But the other company says there is more adjustment with 23 spline. IDK. Like I said "I assume" this is what the deal is.

Airtronics quality has slipped a lot the last two years on servos. They just do not last anymore unless they are servos that are over two years old.

Jr specs are usually very conservative on their servos meaning they are usually faster and stronger than the specs suggest. I would say Ko and Futaba are about the same as Jr so you can compare specs across the brands. Hitec's 5955 is a great servo and seems as fast as a Futaba 9351 but their older 5925/45 servos were trouble sometimes.

Currently I run Hitec 5955 on steering and Futaba 9350 (most bombproof servo ever but a little weak at 139 oz of torque) on throttle. I had a 9351 go bad after two races and another wear out the metal gears after a year. I'm not sure why they do not last like the 9350.

The JR 8711 407oz at .15 sec.. the BEST for steering...

.15 seems slow for steering. I stick with .10 or faster for steering.

Yeah, .15 will get you by. But if you want to have that little edge, you will appreciate .10 speed. I liked dropping from .15 to .10 Vehicles drove much more in tune with what I was expecting from them.

i like the torque.. it helps me hold the line better.. but im also running it in a truggy..i could see .10 being better in a buggy.. not as much torque needed..

From low end to high end :

Futaba 9351
Ace Hobby DS-1015
Sanwa ERG VX or VZ*
KO Propo PDS-2368*
KO Propo PDS-2386 ---> stronger than 2368 but slower
Hitec HS-5955TG*
JR 9100T
JR DS8711*

*I'm using those servos for throttle & steering in my cars.

jr Z series servos are Great. a bit pricey at just over 100.00 each. but worth it imo. plus JRs 3 yr warrenty is nice.

The 8711 is sick.. not that many people run it, i let them drive my truck and everytime thier reaction is always..."i gotta get one"
