Absolutely love this servo. Have had one in a Blitz for almost a year now. Works great! No glitches. Ordering another one for my son's Blitz.

Great Servo. Ultra smooth, fast, and strong. Don't have any idea how they can sell it for $80. It's better then then the more expensive servo's ive used. It's basically a JR Z9100s. Uses same horn size as a JR servo. I recommend getting the Dynamite horns because they slide right on. Perfect fit.
This servo came in a FT RC10T4 roller I bought off eBay (no servo saver). I'm fairly new to the hobby, and this was my first RC. 6 months and many violent crashes later it is still going strong. You'll notice the noise, but it's not annoying. Considering this servo was ran for who knows how long before I bought it, then survived my slow, steep learning curve and is still going strong in my new T4.2 is testament to its durability, longevity, and performance.

Heard from local indoor clay track folks, that a lot of them were running this sevo. Most of them on Losi, but I purchased for a Slash 2WD VXL. I'm pleased with its performance, but have only ran it for one indoor practice. Seems really fast. Quality product, does not glitch.

It was either this or the Savox SC-1258TG, which has pretty much the exact same specifications and price. I decided since I would be running this paired with a castlecreations esc, I would go with the Spektrum since the Savox servos tend to be power hungry on the internal BEC's. Very fast and strong for the price. A little loud, but worth it for the price.

Just put one of these in my XXX-T MF2. Very fast servo. I can tell already I'm going to like it over the HS625MG pos I had in there. LOL I bought a second one to go in the buggy and I will buy a third for the SCTE too.

Best servo buy going! Have one in my FT SC10 2wd and it's fantastic. Very fast, smooth, powerful, and quiet. Not a single thing to complain about. Unless you NEED a servo with more power, you can't go wrong with this one.

I have one of these in my RC8Te and its been awesome. I know its not recommended for 1/8th scale applications but i have yet to have and issue with it and it really does move those big truggy wheels side to side wicked quick and with out an issue. I have also had plenty of big spills with my truggy and like i said am yet to break it. If you curious and want a quick as steering servo i highly recommend it.

This servo is very reliable for racing indoors. i haven't raced outside yet but i think it will do just as good. i have no idea how they could sell this good of a servo for $80. i have this on my traxxas slash vxl and it made it run a lot faster. i cant wait to use this on my sc10
