DS1015 vs. JR 9100s
 

the only servo i have ever used on all my setups for both steering and brake is the JR 9100s. it provides plenty of torque and blazing speed and i have always been happy. however, i am looking at the DS1015 from Associated or Ace RC now cuz i like the style of them better. i am wondering if anyone has used them before and how have they been. are they as good as the JR 9100s? specs are very similar on both.

JR 9100S:
Specifications:
Type: Digital Ultra-Speed Metal Gear Servo
Torque: 150 oz/in @ 4.8V, 180 oz/in @ 6V
Speed: .08 sec / 60 degrees @ 4.8V, .06 sec / 60 degrees @ 6V
Dimensions (WxLxH): 0.827"x1.59"x1.569"
Weight: 2.3 oz
Bearing: Dual Wide Spaced Bearing
Motor Type: Coreless
Gears: Metal


DS1015 specs:
Transit time: 0.108 sec/deg @ 6V
Torque: 14.5 kg/cm (201.4 oz/in) @ 6V
Weight: 66g (2.328 oz)
Length: 41.8mm
Width: 20.6mm
Height: 39.6mm

couple DS servos I seen developed quite a slop after few races all been replaced by JR servos. On the other hand i know many people happy with the DS servos. Now choose :)

I got JR9000T in my maxx for steering, 9100T in mugen for steering, 9100S for throttle in mugen and never had any issues.

but with the price increase of JR servos i got the new brushless Futaba servos for my D8.

BLS452
SPECS:
Torque: 156 oz-in (11.2 kg-cm) @ 4.8V 194 oz-in (14 kg-cm) @ 6.0V
Speed: .18 sec/60° @ 4.8V .14 sec/60° @ 6.0V
Size: 1.6 x .8 x 1.4" (40 x 20 x 36.8mm)
Weight: 58g (2.0oz)

BLS451 is meant fot throttle/brake as it's 147oz/.10 at 6V

I really like JR servos, but they used to cost $110.

The DS1015 serovs I have used all got sloppy after only a short while. Replaceing the upper case on the servo fixes it but it got sloppy again quickly. I have heard that they have addressed it by adding a bushing into the case now though and I havent tried it yet. I actually found the 9100S to be too fast for me. I drive better with a servo in the .10 to .15 range speed wise. Thats just me. I might be too oldand slow for the super fast servos.

This is just my findings. I Prefer the 9100T servo better for steering.
